Weha 1-3/8" Wet/Dry Core Bit

Weha 1 3/8" High Speed Diamond Core bit for granite, marble, quartzite, quarts, engineered stone, concrete counter tops, and all natural stone. The Weha 1 3/8" High Speed Diamond Core Bits are built to be the best dry diamond core bit for granite and engineered stone counter top faucet hole drilling. With diamonds both inside and outside the barrel to reduce drag, heat, and friction, along with high diamond content segments, the Weha dry diamond core bits will drill holes in 3cm granite in less than 30 seconds.

Features:

• Fast drilling segments
• Two sided core protection
• Use it Dry:These granite and stone core bits can be used dry for job site counter top applications. Which include: faucets, sink corners, creating radius holes, grommets, and other on site fabrication work. Just screw them onto a grinder, turn up the rpms and get it drilled fast!
• Use it Wet:For in shop use, were granite counter top fabrication is primarily done wet, attache the Weha Blitz Diamond Core Bit to any air polisher, or electric wet polisher and run at least 4,000 rpm. It will drill just as fast, if not faster, than wet core bits.
• Bites Fast:When starting to drill the most important thing is getting the diamond core bit to "bite" into the stone as fast as possible to prevent walking. The Weha Blitz High Speed Diamond Core bit diamonds are fully exposed from the get go. This allows the bit to suck down into the stone the millisecond it touches the stone to prevent any chance of walking.
• Drill Many Holes:Just because the Blitz Diamond Core Bits are fast doesn't mean they won't last long. Depending on use,thickness of the material, hardness of the stone, and the abrasiveness, one can fully expect between 60-150 holes per bit.
