Core Bits & Non-core Bits by Weha
Weha Puma T-Segment Core Bit Side Diamonds
- The Weha Puma T-Segment has a full drilling depth of 2 ¾” when the segment is worn completely down. This gives plenty of drilling depth for all countertop applications but is short enough to offer solid control when drilling
- The Puma T-Seg Core bit has vacuum brazed diamonds on the outside core to help with the drilling process by hand. It also helps if you need to make the hole just a little bigger and clean up the hole as well.
- The 4 turbo-style diamond segments act like a typical turbo diamond blade by allowing air and water(when run wet) to get in the segment while drilling as well as channel the dust out to help cut and core faster.
- The Puma T-seg diamond core bit is a very affordable core bit that offers outstanding performance. Dollar for dollar, the Puma core bit is the best for granite, quartz, quartzite, marble, and other stone.
