The Dewalt metal drill bit is of the Extreme 2 type.

The tip of the cutter/guide starts drilling upon the first contact with the material, eliminating slipping for clean and precise holes (only for diameters 4.8mm and above).

The innovative conical web structure significantly reduces the risk of breakage.

Anti-slip shank with 3 flat surfaces prevents slipping in the chuck (only for diameters 5.0mm and above).

Permanently marked size indicators above the shank's contact point with the chuck for greater visibility and ease (only for diameters 3.0mm and above).

The Extreme 2 metal drill bit is designed to maximize drilling performance and offers:

• Faster drilling – up to 4 times faster than standard HSS-R drill bits.
• Increased durability – up to 50% stronger than standard HSS-R drill bits.
• Clean and more precise holes without burrs due to the countersunk cutting wings.
