High speed hole saw with built in arbor. Used in applications such as cutting wood, plastic, or any machinable metal, including tool steel and stainless steel. Pilot drill must be used.
Reinforced to cut stronger, last longer and resists tooth strippage. High speed steel teeth resist breaking and offer extended life. Thick backing plate with holes for drive pins resists damage due to high torque.
Thin wall hole saw gives professionals a hole making solution with impact drivers. 1/4" quick change hex shank. Utilizing a thin wall, 8 TPI design, delivers a burr-free cut faster than standard bi-metal hole saws. The included ejection spring removes the frustration of manually removing slugs by automatically ejecting the material. A stop shoulder design prevents over-drilling into material and potentially damaging inner components of electrical and junction boxes. For use in plastics and thin gauge metals up to 1/8" thick. 2.5" length.
Fast metal drilling speeds for double tooth design. Easy plug removal for ejection spring. Raised shoulder helps to prevent the drill from breaking through the material when hole is complete. Thin-walled design optimum metal drilling efficiency. Sharper tooth geometry. Thick, hardened backing plate. Deep-cut style. Increased high speed steel height
