GENERAL INFORMATION Safety Basics
Improper use of abrasive products might cause grinding wheel breakage and serious injury. Comply with ANSI B7.1, OSHA and Safety Guide furnished with package. Don't overspeed, abuse, or drop wheel. Always use a guard, personal protective equipment and proper mounting procedures.
WARNING
Properly matched flanges
Mis-matched flanges – do not use
Safety Gloves Grinding applications are conducted in harsh environments. The use of proper fitting gloves is recommended.
Flanges When mounting most grinding wheels, use flanges of equal diameter and bearing surface. For exceptions, see ANSI B7.1.
Speeds Check machine spindle speed and speed listed on machine against safe maximum operating speed marked on the grinding wheel. Do not overspeed the wheel.
Hearing Protection Use of abrasive products can create elevated sound levels. Hearing protection must be worn where required.
Eye/Face Protection Always wear government- approved face and eye protection when using abrasive products.
Wheel Guard Always use the wheel guard as supplied by the machine manufacturer, in the proper position.
Do Not Use Damaged Wheel
Always check each wheel for cracks or damage before use. Never use a damaged wheel.
Dust Protection Exposure to dust generated from workpiece and/or abrasive materials can result in lung damage and/or other physical injury. Use dust capture or local exhaust as stated in the SDS. Wear government-approved respiratory protection and eye and skin protection. Failure to follow this warning can result in serious lung damage and/or physical injury. This is a general dust warning and does not cover specific situations. For more information, refer to the SDS dust warning provided with your products, and workpiece.
Safety Guides, SDS and Wheel Warning Messages Before using any abrasive materials, READ: • The Safety Guides
• Wheel Warning Messages • Safety Data Sheets (SDS)
All Norton products provide information pertaining to safe use. Please take the time to read it carefully. Contact suppliers of the workpiece and abrasive materials for copies of the SDS if one is not readily available. Norton abrasives SDS can be obtained on www.nortonabrasives.com

METAL FAB GRINDING AND CUTTING Depressed Center Wheels
Depressed center wheels may also be referred to as raised hub wheels or by their shape designation of “Type”, with Type 27 being the most popular. The depressed center design allows the flange/lock nut to recess within the wheel so that it can be used for various grinding and cutting applications. Depressed center wheels are designed to handle the most severe right angle grinding applications from heavy stock removal to rough blending. More recently, depressed center wheels have been designed to increase the utility of the tool for cut-off applications. While large right angle grinders (7" & 9") have been around for many years, small or mini grinders that handle 4", 4-1/2", 5", and 6" wheels have made this machine, and wheel category, the most popular in power tools. Applications: Grinding, stock removal, edge chamfering, beveling, weld blending, and cutting-off Size Range: 2" – 9" Thickness Range: .040" – 1/4" Grit Range: 24 – 46 grits for stock removal; 60, 80 grits for blending and finishing Abrasive Grain: Ceramic Alumina, Diamond, Zirconia Alumina, Aluminum Oxide, Silicon Carbide Mounting Options: Plain hole (3/8", 5/8" and 7/8") and discard mount (5/8"-11) Shape: Type 27, Type 28, Type 29 Machine Used: RIGHT ANGLE GRINDER The complete product category is described above. See Norton Full Line Catalog #7362 for entire offering.
How to Pick the Right Mount
Most wheel sizes come with a plain hole or a discard mount option. While the plain hole has a small, initial cost advantage, the discard mount can provide a labor cost advantage with the quicker wheel change. Mini-Mount Hub
Our unique, patented mini-mount hub used on 4-1/2" and 5" depressed center wheels provides up to 30% more wheel life because the hub covers just a small surface area, providing maximum grinding area exposure and usage.
Standard throw-away hub size
Why Choose Depressed Center Wheels?
Depressed Center Wheels vs. Flap Discs or Fiber Discs • Up to 5X life over flap discs, less downtime and inventory • Up to 100X life over fiber discs, less downtime and inventory • Rigidity for severe operations and high power grinders • 1/8" wheels can be used for cutting and grinding • Can be used to grind inside corners at outer edge of wheel

Coated and Non-Woven Abrasives

COATED AND NON-WOVEN ABRASIVES Coated Abrasive Basics
Coated Abrasives A coated abrasive product is made up of three basic raw materials: an abrasive grain, the backing onto which the abrasive is applied, and an adhesive bond.
Abrasive Types Emery (6) Emery is a dark gray, round-shaped grain which tends to polish rather than abrade a work surface. • For polishing and cleaning metal only Garnet (5) Garnet is reddish brown in color. This natural abrasive is medium hard and relatively sharp, but not as durable as synthetic abrasives. • For use on wood only • Particularly good for soft woods such as pine
Heat-treated Aluminum Oxide (2) Heat-treated aluminum oxide is a tough but cool cutting abrasive which gives both long life and freeness of cut on a wide range of materials.
• Ferrous metals • Wood sanding Zirconia Alumina (8)
Zirconia alumina is an ultra-tough, synthetic abrasive which provides a free, cool cut for high stock removal applications. It is tougher and sharper than aluminum oxide. It has a micro-crystalline structure which
allows for controlled breakdown and self-sharpening. • Heavy-duty snagging and grinding of all ferrous and non-ferrous metals • Abrasive planing of wood, plywood and particleboard • Grinding fiberglass, rubber and plastics Ceramic Alumina (9)
• Produces an excellent finish Silicon Carbide (4)
Silicon carbide is the hardest and sharpest of the manufactured abrasives. Because of its extreme sharpness, this bluish-black abrasive grain permits fast stock removal and cool cut. • Cast iron • Non-ferrous metals, i.e. brass, aluminum and bronze • Non-metallics, i.e. glass, rubber, plastic and stone • Final finish on wood and stainless steel • Abrasive planing particleboard Light Brown Aluminum Oxide (2) Light brown aluminum oxide is a tough, yet sharp synthetic abrasive characterized by cool cut, long life and the ability to break down under pressure, producing new cutting edges.
The sub-micron structure of ceramic alumina allows each grain to continually expose sharp cutting points, resulting in a cooler cutting action and an extended life. • All ferrous/non-ferrous metals, carbon steel and exotic alloys Engineered Shaped Ceramic (9) Engineered shaped ceramic grain features a consistent shape from grain to grain along with razor-sharp cutting points. The unique patented geometry and tough micro-structure enable the grain to stay sharp, as new cutting points are exposed when the
grain fractures. • Carbon steel • Aluminum • Stainless steel • Hard-to-grind metals
• Production wood sanding • Non-ferrous metal finishing Brown Aluminum Oxide (2, 7)
Brown aluminum oxide is a tough, durable, synthetic abrasive characterized by the long life and wear resistance of its cutting edges. It offers enormous penetrating strength, even at high speeds. • Ferrous metals
• Aluminum • Hardwood

COATED AND NON-WOVEN ABRASIVES Coated Abrasive Basics
Backing Types Backings are the base for the abrasive minerals and, combined with the adhesive bond, support and anchor the abrasive mineral. The backings used in the manufacture of coated abrasives are: Paper Due to the fine surface of paper, a consistent finish is produced. Paper weights include A, B, C, D, E and F weights with A being the lightest and most flexible and F being the heaviest and least flexible. A, B, C and D weight papers are used for hand sanding and light mechanical operations in the form of sheets, PSA (pressure sensitive adhesive) and hook and loop discs and sheet rolls. E and F weight papers are primarily used for more aggressive mechanical operations in the form of belts and discs. Cloth Cloth backings used for coated abrasives are identified by weight. Cloth backings are filled or “finished” with a variety of materials (glues or resins) to create various backing characteristics, most notably flexibility. Several cloth types are used: cotton, polyester, polyester/nylon and polyester/cotton blends, and rayon. There are three basic weights of cloth: J-weight or “jeans” is the lightest and most flexible. X-weight or “drills” is a heavier cloth that ranges in flexibility, strength and durability and is used on the broadest range of applications. Y-weight is a heavyweight drills cloth used on heavy-duty, high stock removal operations. Fiber Vulcanized fiber (cotton fibers which are chemically treated and then pressed under temperature and pressure to form a very durable backing) is used exclusively as the backing for resin fiber discs. Film Polyester film backing comes in 3 mil. and 5 mil. thicknesses, which have high strength and surface smoothness. They are used primarily in disc and roll applications requiring consistent surface finish, including powertrain applications. Foam Primarily used as backing for sponges, finer grit finishing discs, and buffing and polishing pads for cleaning and moist finishing applications. Mesh Mesh matrix backing comprised of thousands of tiny holes allowing for maximum dust extraction.
Coating Types There are two types of abrasive coatings used in the manufacturing of coated abrasives: open coat and closed coat. Glue, urea resin , and phenolic resin are the three basic bonding agents most commonly used. There are many size coat and make coat combinations, such as glue over glu e, urea over glue , and resin over resin . Glue over glue is the most flexible bond while resin over resin bond is moisture-resistant, harder, less flexible, heat-resistant and has superior grain retention. Bond Types An adhesive bond system is required to secure the abrasive mineral to the backing. All coated abrasive products are made with a two stage bonding process, the make coat and the size coat. The make coat is the first layer of bond applied to the backing. The make coat provides the adhesive base between the abrasive mineral and the backing. The size coat is the second coat , which is applied over the abrasive mineral and make coat to anchor the abrasive mineral and provide the desired physical strength of the finished product.
Open Coat With an open coat, 50% to 75% of the surface is covered by abrasive grain. There are evenly spaced voids between the particles of grain, helping reduce the effect of loading caused by wood dust or metal particles.
Closed Coat With a closed coat, the entire surface is covered with abrasive grain, with no voids between the particles. This is the most typical coating, permitting the greatest degree of stock removal and longest product life.
OPEN COAT (1/3 LESS GRAIN THAN CLOSED)
CLOSED COAT
Super Size Coating The Super Size coat is an optional final coat and grinding aid applied over the size coat to help maintain low grinding temperatures and prevent loading.
How to Read a Coated Abrasive Specification The Norton coated abrasive marking system includes both a generic and a technical marking, which identifies the actual components which make up the product. The markings identify the tradename, abrasive type, bond, backing, and any special features. An example would be: Norton Blaze R980P.

COATED AND NON-WOVEN ABRASIVES Coated Abrasive Basics Coated Abrasive Storage Stored under proper conditions, coated abrasives will retain their efficiency and usefulness over long periods. Improper or inadequate storage can introduce problems of weakened bond, curl, brittleness, and breakage. Temperature and humidity are the two most important climatic factors influencing coated abrasive performance. Backings and adhesives are sensitive to climatic changes and will gain or lose moisture according to the relative humidity of their surroundings. Excessive humidity may cause a softening of some types of adhesive bonds so that the product quickly fills and clogs, or loses its grain during use. Excessive dryness may cause brittleness, reduced flexibility, and distortion of product shapes. As moisture in the coated abrasive product increases or decreases, dimensional changes can occur. When the backing changes more than the adhesive bond, it causes cupping. High and low humidity can cause concave and convex cupping respectively. The newer synthetic-backed belts are not affected by moisture. Broad temperature swings will not permanently harm these products either, but cold temperatures will cause a “cold set” condition. Consequently, these products should be allowed to come to room temperature before use.

Storage Facilities The ideal storage (stock) room for coated abrasives would be one in which all the walls are inside partitions, rather than the outside walls of the building. • Constant levels of humidity and temperature should be maintained. Stockroom temperature should be 60-degrees to 80-degrees F and relative humidity between 35 and 50%. • Cartons should be kept away from damp or cold walls and floors, where they might absorb moisture. • Store coated abrasives away from heat sources – steam heated radiators, steam pipes, hot air inlets, heat ducts, or rooms near furnaces or ovens. • Keep products in original packages. These packages facilitate handling and can be stacked in the most practical and convenient manner. • Bulk rolls should not be allowed to stand on edge after they have been unpacked. Store flat on shelves or pallets. • Narrow belts which have been removed from the carton should be rolled up and stored on edge on a clean shelf. Belts may be draped over a large cylinder, such as a gallon can, brake drum, or flanged hanger of the type used for a garden hose. Never hang a belt from a nail – the backing will crease and the abrasive belt might crack. Wide belts should be hung over a tube of at least 4" diameter. Center the belt joint over the tube and add a light weight (such as old packaging tubes) to the bottom loop of the belt to aid in removing set. Condition for 24 hours prior to use. • For maximum product efficiency, precondition coated abrasive products in a chamber of controlled temperature and humidity before use.

COATED AND NON-WOVEN ABRASIVES
Non-Woven Basics
Introduction Most Norton Bear-Tex products consist of a non-woven web of nylon fibers impregnated throughout with abrasive grain and bonded with synthetic resins. This design produces a cushioned, three-dimensional material that is extremely pliable and long lasting. The uniform dispersion of abrasive throughout the web provides a continuous supply of new grain as the old grain and fibers wear away during use. Norton Bear-Tex products, with their open mesh construction, are waterproof, washable, resilient, conformable, non-loading, non-conductive, non-metallic and non-rusting. Non-woven wheels are easily pre-formed to conform to special-shaped work pieces. Since non-woven products are designed for use where stock removal is not required, they begin where other abrasives leave off. The relatively non‑aggressive nature of nylon and grit inherent in the material makes it ideal as a finishing tool. While 60 to 80 grits are considered intermediate sizes in other products, they are considered coarse for non-woven items. Used wet or dry, Norton Bear-Tex non-woven products offer the following advantages: controlled cut (with little or no stock removal) allows for increased productivity, consistent, uniform finish, ability to automate operations, minimized smearing and reduced operator training. These advantages make our non-woven products an excellent alternative to bristle brushes, set-up wheels, greaseless compounds and steel wool.
Abrasives Ceramic alumina, silicon carbide and aluminum oxide abrasives are offered. Ceramic alumina cuts the fastest and is the most cost effective on large-volume applications. Silicon carbide is sharper, cuts faster than aluminum oxide, and produces finer scratch patterns on most surfaces. Aluminum oxide is more durable and tends to last longer. It causes less discoloration on aluminum, and is more aggressive on certain applications such as hardened steel parts. Norton Bear-Tex hand pads are also available in a non-abrasive material. Grits Grit refers to the size of the abrasive grain impregnated into the nylon web. The coarser the grit, the more aggressive the cut, the rougher the finish. The finer the grit, the less aggressive the cut and the resulting surface finish will be finer, if all other conditions are equal. GRIT DESIGNATIONS GRIT SIZE Extra Coarse (XC) 50 Coarse (C) 60 – 80 Medium (M) 100 – 150 Fine (F) 180 – 220 Very Fine (VF) 240 – 360 Super Fine (SF) 400 Ultra Fine (UF) 600 Micro Fine (MF) 800 – 1200 Densities The product “density”refers to the number of fibers which have been compressed into the nylon web material. Under identical conditions, harder density wheels cut faster, last longer and produce finer finishes than softer density wheels. Softer density wheels offer greater conformability and have less tendency to load or burn the work piece. Fiber Sizing Several nylon fiber sizes are used in the manufacture of Norton Bear‑Tex and Merit web material because the fiber size is a significant factor in the coating process, as each produces distinct cutting characteristics. Bonding Agents Waterproof resins are used in the manufacture of Norton Bear-Tex and Merit web material to bond the nylon fibers together and to firmly anchor the abrasive grains throughout the web.
