Frequently Asked Questions
Do I need coolant when drilling glass or ceramic?
Yes, using coolant helps preserve the tungsten steel edges and prevents cracks.
Can these bits handle hammer action?
Our bits are designed for rotary work, but light tapping on masonry is acceptable.
Are the tips resharpenable?
The tungsten-steel edge can be touched up with a diamond wheel, although replacing it is often faster and more cost-effective.
