Frequently Asked Questions

What materials are Zenesis CNC Finger Bits designed for?

They are engineered for granite, engineered stone, quartz, and other hard countertop materials commonly processed on CNC machines.

What is Patterned Diamond Technology?

Patterned Diamond Technology strategically positions diamonds throughout the tool to promote aggressive cutting, consistent performance, and longer service life as fresh diamonds are continually exposed.

What is the difference between the 4-segment and 7-segment versions?

The 4-segment version provides fast, aggressive cutting for general fabrication, while the 7-segment version is optimized for hard stone materials and delivers exceptional longevity. It can also be used on softer stone for even faster cutting.

What RPM should these finger bits be operated at?

Recommended operating speeds range from 4,200 RPM for harder materials to 5,500 RPM for softer materials.

Should these finger bits be used wet or dry?

Zenesis CNC Finger Bits are designed for wet use only to maximize cutting performance, improve finish quality, and extend tool life.
