Each bit is cut from shock-resistant tool steel and features an advanced hardening process that greatly reduces wear. Its snub-nose design fits perfectly into hex-socket adapters and the tips are precision ground to seat firmly into the screw head. The magnetic drive guide holds 1 inch screwdriver bits to drive screws in a variety of materials. The self-retracting guide sleeve protects fingers and holds screws in place while eliminating wobbling and slipping.
