High quality and long lasting drill bits

by Mark -

Outstanding quality and very long lasting, I've used it many times and cuts keep going clean and smooth as the first day. It was a great investment.

worth the price

by Pete -

I have been going through the normal diamond bits way too fast so I tried these out and they seem to cut through porcelain much better. So far so good!

These bits are a bit more than others but you get what you pay for. They definitely out cut any other bit on the market. We drill a lot of porcelain and they go through. Not fast but we aren't supposed to drill fast. They get through and are not burned out after a few holes. I have purchased almost every size available and I highly recommend them.
