Thank you for viewing this listing.

With regular steel drills, titanium coating provides temporary heat resistance, but the bit wears out and becomes dull before the tip gets too hot, leading to increased friction and burnt edges.
By applying a nitriding surface treatment, we've enhanced rust and wear resistance, resulting in smoother friction, reduced heat generation, and improved sharpness and durability.

The spiral grooves quickly discharge chips during cutting, reducing processing resistance.
Although not shown in the images, the hole dimensions are marked on the body.

Affordable enough to use without worry, supporting professional work!
