Weha Blitz High Speed Dry Diamond Core Bits are premium grade for super fast cutting.

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.

The Weha 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.
But they can also be used wet with Air Polishers in shop applications.

What makes the Weha High Speed Diamond Core Bit different from others and the best Diamond Core Bit on the Market?

Speed of drilling: The Weha Blitz Diamond Core Bits will drill a hole through 3cm Uba Tuba Granite in less than 30 seconds at 10,000 rpm.

Interior and Exterior Diamonds on the Barrel: A lot of Diamond Core Bits have diamonds on the outside of the barrel. But the Weha Blitz High Speed Diamond Core Bits have double Vacuum Brazed diamonds on both the outside AND the inside of the barrel. The vacuum brazed diamonds on the inside and outside promote faster drilling when the bit is being "rounded" during the drilling process. The vacuum brazed diamonds on the outside also allow you to enlarge the hole. So if you need to make the hole a little bigger, just run the Weha Diamond Core Bit like a Vacuum Brazed Zero Tolerance wheel and make the hole bigger. This also works excellent when you are doing inside and outside radius holes or making grommets fits nice and smooth. The diamonds on the inside barrel also enhance speed drilling and helps promotes the stone core to drop out much easier.

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 makita, metabo, hitachi, or any other 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.
