Hardwood (mahogany, oak, laminate)
Engineering plastics (nylon, polycarbonate)
Composite materials (carbon fiber, fiberglass)

QUESTION: Why is the 4-flute design more efficient than traditional drills?
Four-flute staggered cutting: simultaneous force from 4 cutting points, feed resistance reduced by 60%.
Serrated chip removal design: chips are automatically separated to avoid clogging.
Self-sharpening alloy: the more you use it, the sharper it gets, and the life expectancy is increased by 5 times.
Measured drilling speed on 12mm steel plate is 3 times faster than ordinary drills!
QUESTION: How to use the eccentric positioning function correctly?
Operating Principles:
When starting the drill, first lightly touch the material surface at an angle of 30°.
Gradually press down vertically after feeling the automatic correction of the eccentric mechanism.
No additional lateral force is required.
The magnetic grip is really strong! Screws stay in place without slipping, which makes assembling furniture and repairs so much easier. No more dropping tiny screws!
Super durable and well-made. I’ve used them for multiple projects, and the anti-slip design really helps prevent stripping. Even with heavy use, they still work like new!
Great variety of sizes! Whether I’m working on electronics, furniture, or home repairs, I always have the right bit. Fits perfectly with my drill and holds up well over time.
