Viper T-Seg Granite & Engineered Stone Wet/Dry Core Bits

Drill fast, clean holes in granite, quartz, and engineered stone with premium T-segment core bits built for maximum durability and long life.

Looking for a Core Bit That Delivers Faster Cutting and Longer Life?

The Viper T-Seg Granite & Engineered Stone Core Bits are engineered for professional fabricators who need clean, accurate holes in granite, engineered stone, marble, and quartzite. Featuring an advanced T-segment weld design and a high diamond concentration, these premium core bits provide aggressive cutting performance while significantly reducing the risk of segment loss on even the hardest materials.

Diamond brazing on both the inside and outside of the bit helps produce cleaner holes while making core removal easier. Large side slots improve debris evacuation and cooling, allowing the bit to cut efficiently and extend tool life in demanding fabrication environments.

Designed for both wet and dry drilling, Viper T-Seg Core Bits offer outstanding versatility for fabrication shops and field installers alike. For maximum performance and when drilling difficult materials such as quartzite, wet drilling is recommended.
