Set de burghie pentru metal DeWALT - Extreme DT4921-QZ, 10 buc.

Descriere

The metal drill bit set DT4921-QZ from DeWALT is designed for precise and efficient drilling of hard metal surfaces. The tools are made of high-speed steel with 5% cobalt content (HSS-Co), which provides high wear resistance and protects the drill bits from overheating under heavy loads. Thanks to the special No-Walk tip, the drill bits start drilling easily and accurately without pre-centering, including on surfaces thicker than 5 mm. The tri-flat shank ensures a stable grip in the chuck and eliminates the risk of slipping during operation, guaranteeing clean and concentric holes without burrs.
