Frequently Asked Questions

What material is the drill made from?

The drill is forged from a 5% cobalt alloyed high‑speed steel (HSS‑Co), providing superior heat resistance and wear resistance.

Can I use this drill for aluminum?

Yes. With the optional TiN coating, the drill performs exceptionally well on aluminum, offering higher cutting speeds and reduced built‑up edge.

Is the shank compatible with a 5‑mm collet?

The straight shank conforms to standard dimensions and fits 5‑mm, 6‑mm, and 8‑mm collets as well as standard chucks.

How do I maximize tool life?

Use proper cutting speeds, apply adequate coolant, and avoid excessive feed rates. Periodically inspect the cutting edge for wear and re‑sharpen when necessary.
