Drill Bits is efficient and versatile drilling.Impact-resistant screwdriver head - for high impact and high strength screwdriver, suitable for screwdrivers, especially the impact screwdriver screw deep bite effectively reduce the head slip, greatly improve the work efficiency hardness ≥62hrc - high precision optimized material. The hardness of the drill head is as high as 62HRC, more robust and durable mechanical principle design - strong torque, high torque after contact with the screw head, the collision reaction force is partially absorbed by the torque, effectively preventing the tool head from breaking shock-proof - fast through the metal shock-proof, no rupture, easy to penetrate the metal plate with dovetail nails.Anti-impact screw head -- suitable for high impact, high strength screw head, suitable for impact screw head, especially impact screw head deep bite, effectively reduce head slip, greatly improve work efficiency hardness ≥62hrc -- high-precision optimization material. Drill hardness up to 1326HRC, more durable mechanical principle design - strong torque, high torque after contact with the screw head, collision reaction force part is absorbed by torque, effectively prevent the head from breaking shock-proof - fast through the metal shock-proof, no rupture, easy to penetrate the metal plate with the tenon nail.
