Frequently Asked Questions

What is a blind hole CNC bit?

A blind hole CNC bit is designed to drill holes that do not pass completely through the material. Diamut's design also prevents the stone core from remaining inside the bit, helping speed up production.

What is the advantage of not leaving the stone core behind?

By eliminating trapped stone cores, fabricators spend less time clearing tooling between drilling operations, improving productivity and reducing machine downtime.

What materials are these bits designed for?

Diamut Blind Hole CNC Bits are designed primarily for natural stone countertop fabrication, including materials such as granite, marble, and quartzite.

What thread connection do these bits use?

These bits feature a standard ½ Gas thread, making them compatible with CNC machines designed for this connection.

What sizes are available?

Diamut Blind Hole CNC Bits are available in diameters ranging from ¼ inch to over ½ inch, providing options for a variety of drilling applications.

Why do professional fabricators choose Diamut Blind Hole CNC Bits?

They are valued for their fast cutting speed, long service life, and innovative design that eliminates leftover stone cores, helping fabrication shops improve efficiency and maintain consistent production.
