Feature
✔ Titanium-Coated HSS Construction – Hardened and precision-honed for exceptional sharpness, extended lifespan, and 3× faster drilling vs. uncoated bits. Double U-flute design ensures efficient chip removal.
✔ Optimized Flute & Split Point – Fully ground spiral flutes reduce friction and heat for cooler operation. 135° split point prevents walking—no center punch required—ensuring precise, clean holes in wood, plastic, aluminum, copper, and low-carbon steel (<5mm).
✔ Quick-Change Ready – Effortless bit replacement without re-chucking—ideal for corded/cordless drills and drill presses.
✔ Complete 19-Piece Kit – Sizes 1–10mm stored in a compact, organized case—no more lost bits.
⚠ For soft metals, wood, plastic & aluminum alloy only. NOT suitable for concrete, masonry, glass, or ceramics.
💡 Pro Tips
Keep Vertical
- Keep the drill bit vertical with the stuff's surface to be drilled.
- A tilted bit is prone to break during drilling.
- Be sure to make both the bit and the workpiece stable.
Stay Cool
- Friction between bit and metal will accumulate an amount of heat.
- It's necessary to use cooling liquid during drilling to keep the bit cool. Otherwise, the bit may fry(melt) or only last a short time.
- It's both fine to use lubricant oil and to pour water.
Clean and Smooth Output
- No cracking
- Clean and smooth.
Precise & Fast Drilling
135 degree split point with straight shank prevents drill bits walking and makes drilling precise. No center punch is needed.
Quick Discharging & Cool Drilling
Fully ground spiral groove design aims to discharge scrapes as soon as possible and also to decrease friction and heat for a faster and cooler drilling performance.
Few Efforts & Higher Efficiency
Round Shank as the most usual shank style is rather accurate in centering, close-up lock, and ideal for a quick change.
