DoAL~s Dart : The carbon-alloy steel blade with spring tempered back for all contour
and cutoff band machines. The Dart is available in three tooth forms (Precision~ But- tress® and Claw Tooth®) and in three set patterns (raker, wave or straight set). Compared with ordinary hard-edge, flex-back carbon blades, the Dart will- • Cut harder, more abrasive materials with its hardened and tempered teeth ■ Provide up to 50 percent more sawing life cutting dry and up to 300 percent greater life cutting wet
■ Withstand band tensions up to 50 percent greater than those that can be applied to standard carbon blade while resisting stretching and twisting ■ Allow heavier feed forces to be applied, permitting faster cutting ■ Produce straighter, more accurate cuts ■ Better resist "mushrooming" or scoring of the back edge and sides The spring-tempered back of the Dart band has 50% more tensile strength than ordinary carbon steel saw blades. This increased tensile strength allows the use of high band tension, which in turn gives more accurate cuts at
The Dart handles your hardest, toughest cutting jobs, and lasts longer than ordinary carbon alloy blades. heavier feeding pressures. The increased hardness of the band back (44 Re) better resists "mushrooming" of the back edge and provides greater resistance to scoring than does the standard carbon blade. Choose the right Dart for your needs from the chart below. Caution: The Dart is not suitable for speeds in excess of 4000 sfpm.
