Starrett Cordless Smooth Cutting Hole Saw 40mm

TOP-QUALITY: CSC Cordless extra cobalt hole saw is made with hardened and abrasion-resistant high-speed steel teeth and an alloy body and cap for exceptional performance and toughness. EXCELLENT DESIGN: CSC hole saw has a constant pitch of 8 teeth per 25mm/inch for super smooth cuts. The side grooves speed up the chip evacuation. Flared safety stop cap at the base of the hole saw prevents drilling beyond the maximum cutting depth of 13mm (1/2") to avoid accidents and damage. EFFICIENT: Our hole cutter is designed for use with battery-operated power tools, CSC hole saws will cut twice as many holes as the equivalent standard hole saw per battery charge. EASY TO USE: Insert the pilot drill until the hole saw wears the materials surface. When the saw starts to cut, slowly cut it into the material without pushing. After the hole saw passes through the other side of the material, stop the drill. COMPLETE ASSEMBLY: Comes as a complete hole saw assembly, including an arbor, pilot drill, and ejector spring to meet your professional needs. Therefore, no need to purchase a separate arbor and pilot drill kit.
