DoALL Band Saw Blades US 2023

Pitch Selector for Solid Material The pitch indicates the tooth spacing. The correct pitch choice ensures proper tooth pressure and adequate gullet capacity for chips. In most applications, a blade should engage no less than 3 teeth and no more than 25 teeth in the cut. SINGLE PITCH • Single pitch blades have uniform tooth spacing and shape. • Pitch (teeth per inch) is the number of gullets in a 1" (25.4 mm) span. • Use primarily for solids on rigid machines. MULTI PITCH • Multi pitch blades have a varying tooth spacing to reduce vibrations.

• Pitch designation hyphenates single pitches of coarsest and finest teeth. • Use for most sawing applications. • Best for structural materials or any vibration-prone application

Helpful Hints When Choosing Blades: • For fast, accurate sawing, choose the widest blade that fits the machine • For contour sawing, choose the widest blade that will cut the smallest part radius

• Consider a single pitch blade for fast cutting materials as single pitch blades have consistent tooth spacing • Use a multi pitch blade for most metal sawing applications where harmonics need to be controlled Better Results Will Come from Following DoALL Blade Expert Advice:

• Thinner blade option for longer flex life over small band wheels • Thicker blade option for straighter cuts under heavy feed force • Standard set for most applications • Wider (heavier) set to avoid pinching in highly stressed metals • Raker set for sawing ferrous and tough metals • Straight set for easily machined metals and non-metals • Straight raker set is used for all multi pitch blades

• Precision tooth shape for most sawing applications • Claw/hook tooth shape to increase beam strength and penetration • Buttress/skip tooth shape for woodworking applications • Neutral rake blade for most work narrower than two inches • Positive rake blade for wider, tougher-to-penetrate work
