Frequently Asked Questions

Q: What type of screwdrivers and drills are these bits compatible with?

A: These bits feature a standard 1/4" (6.35mm) hex shank, making them compatible with electric screwdrivers, cordless drills, air drills, and manual screwdrivers equipped with a 1/4" hex chuck or bit holder.

Q: Are these Torx bits magnetic, and why does that matter?

A: Yes, each bit tip is magnetic, which allows screws to cling to the bit during installation and removal. This is especially helpful when working in tight spaces, overhead, or anywhere dropping a screw would be a problem.

Q: What material are these drill bits made from?

A: The bits are crafted from S2 alloy steel — a high-hardness, impact-resistant material widely used in professional-grade screwdriver bits. This ensures long-lasting performance and resistance to wear and cam-out under heavy torque.

Q: What is the difference between the 75mm and 100mm lengths?

A: The 75mm bits are ideal for standard, everyday fastening tasks, while the 100mm bits provide extra reach for deep recesses, cavities, or hard-to-access fastener locations commonly found in appliances and vehicles.
