FAQ

Do I need coolant when drilling glass or ceramic?
Yes—steady water flow preserves tungsten steel edges and prevents cracks.

Can these bits handle hammer action?
They’re engineered for rotary work; light tapping on masonry is acceptable.

Are the tips resharpenable?
The tungsten-steel edge can be touched up with a diamond wheel, though replacing is often faster and cost-effective.
