Description

Keyhole saw HSS bimetal Design: Bimetal construction for maximum safety, wear resistance and precision. No breaking even under increased load. Combi toothing 4/6 teeth per inch for a low-vibration run in material from 2 mm. With solid base plate for more threads, thus increased concentricity and lateral runout accuracy. The slots at the side make core removal easier. Cutting depth 38 mm. Supplied without mount shaft and without drills. Application: For use in connection with drills or cordless drill, allows large-calibre, exact drilling e.g. for pipe conduits in airconditioning, automobile or systems engineering. Can be used on drilling machines and powerful cordless screwdrivers. HSS. For universal application and steels up to 850 N/mm².
