Feature:

Shock Resistant Screwdriver Bits- Built for high-impact high_strength screwdriving,Suitable for screwdrivers, especially impact drivers

Non-slip serrated blade- Saygooibye to screwslippage Screw deep bite effectively reduces head slippage Greatly improve work efficiency

Hardness≥62HRC-High precision optimization Material. The hardness of bit head is as high as 62HRC stronger and mofe durable

Mechanics Principle Design- Strong torque,high torque After touching the screw head Impact screwdriver The resulXting collision reaction force partly absorbed by torsion Effectively prevent the cutter head from breaking

Shock Proof-Qufckthrough metal Shock reststantand notcracked Easily penetrate metal plates with dovetail nails
