Frequently Asked Questions
Q: What is a square screwdriver bit and how is it different from Phillips?
A: A square (Robertson) screwdriver bit has a square-shaped socket that fits into a corresponding square screw head recess. Unlike Phillips bits, square bits are far less prone to cam-out (slipping), providing a more controlled and powerful drive — ideal for woodworking, cabinetry, and construction fastening tasks.
Q: Are these bits compatible with my cordless drill or impact driver?
A: Yes! These bits feature a standard 1/4-inch (6.35mm) hex shank, which is universally compatible with virtually all cordless drills, electric screwdrivers, impact drivers, and quick-change bit holders.
Q: What is the difference between the 50mm and 65mm bits in this set?
A: The 50mm bits are ideal for standard, everyday fastening tasks in normal-depth screw holes. The 65mm bits offer extra reach for driving screws into deeper recesses, tight corners, or areas where added length provides better control and access.
Q: Is S2 Steel a good material for screwdriver bits?
A: Absolutely. S2 steel is a shock-resistant, high-hardness tool steel specifically engineered for screwdriver bits and other high-torque applications. It delivers excellent durability, resists breakage under stress, and outlasts standard chrome vanadium bits in demanding conditions.
