Frequently Asked Questions
Q: What materials can these HSS hex shank drill taps be used on?
A: These High-Speed Steel drill taps are designed to work on a wide range of materials including aluminum, iron, steel, wood, and plastic. The hardened HSS construction handles soft to medium-hard materials with ease for both drilling and tapping in a single pass.
Q: Do these bits fit standard power drills and drill drivers?
A: Yes! The 1/4" (6.35mm) hex shank is the industry-standard quick-change size, making these bits compatible with virtually all cordless drills, electric screwdrivers, and drill presses that accept 1/4" hex shank accessories. No adapter needed.
Q: Why are there 12 pieces for 6 thread sizes?
A: The set includes 2 drill taps per thread size (M3, M4, M5, M6, M8, M10), giving you a backup for each size. This is especially handy on longer jobs or in case of wear, so your work is never interrupted by a missing bit.
Q: What is the benefit of the wide spiral groove design?
A: The wide spiral flutes are engineered to pull chips and debris up and out of the hole as you drill and tap. This prevents chip buildup in the cutting zone, reduces binding, extends bit life, and produces cleaner, more accurate threads.
