GAGE l
Blade Set Set describes the total amount the teeth are offset to pro- vide side clearance for the back of the band.
Blade Gage Blade gage refers to the thickness of the blade stock. Heavier gage blades provide greater beam strength ... Where blade width is limited by machine capacity or radius cutting requirements, beam strength can be in- creased by using the same width blade in a heavier gage. Tooth Form Tooth form refers to the shape and profile of the tooth and gullet. Three types of tooth forms are offered by DoALL, each of which was originally developed for a specific pur- pose. These include:
Raker Set teeth have a pattern in which one tooth is offset to the right, the next to the left, and the third straight. It is recommended for general purpose work, especially con- touring.

Precision~ The Precision tooth form is the most versatile. Because of its smoothly radiused gullet, it is recommend- ed for both the most intricate contour work and straight cut-off work. It should be selected for finest edge finishes, thin workpieces and extremely small radii. Precision tooth form is available in the greatest selection of blade types.
Wave set teeth are set in a gradually offset pattern from one side of the blade to the other, to provide a smooth cut- ting action on tubing, angles and structurals; or on any work where the cross section of the workpiece is not con- sistent.
Straight set teeth alternate left-to-right, tooth-to-tooth. These blades are recommended for free cutting work- pieces in softer non-ferrous metals, plastics and wood. Available only in carbon alloy-type sa·., blades.
Buttress~ Buttress tooth forms are similar to Precision, except that the gullet has been lengthened to handle lar- ger chip loads. It is recommended for accelerated cutting of non-ferrous metals, wood and plastics.
Claw Tooth~ The Claw Tooth form has a 10-degree posi- tive rake angle and a lengthened gullet similar to the But- tress tooth form. The Claw Tooth provides faster cutting of all metals, wo~ds and plasti?s, and is particularly recom- mended for thick work sections. The positive-rake teeth li_terall~ pull themselves into the work. This great penetra- ting ~b1l1ty allows lower feed pressures, thereby extending tool life.
