The diamond particle coating on Drilax hole saws gives superior performance and lifetime. Please note our tools do not need center pilot holes. Center pilot hole drills are mostly for wood, metal, etc.

The electroplated diamond coating will wear off if the tool gets too hot. Never let your drill bit run dry.

Shank size is 3/8 inch – suitable for standard drills. Maximum depth of cut is 1-1/8 inch

Please see our instructions page for more information.

Here is how you could use water to keep the tool cool:
a- You can build a mini water dam around the hole with plumbers putty.
b- You can choose to spray water on the drill bit.
c- Or you can use running water to cool the drill bit.
Center pilot drill bits are for wood, metal, etc.; Here is how you can keep the drill bit on target:
a- You can make your own guide out of plywood – plastic or even cardboard. All you need is to keep the drill bit in place until it makes the initial marks.
b- You can start drilling at an angle, with the edge of the drill bit making a C slot and then getting the drill bit up to vertical.
c- You can manually guide the drill bit with a wet sponge.

We thank our customers for their support and great reviews. Here is one of the reviews on Amazon Product Page.

“This 4 inch diamond hole saw was amazing. Cut better and faster with a cleaner cut than several of my expensive bits. Keep the cutting area wet and lift often to let freshwater in to cut and cool bit off with drill weight only, and it will cut thru 3/8″ ceramic tile like a hot knife in butter. Strongly recommend these hole saws by this manufacturer. These bits even look identically like several of my expensive ones from a supply house and the depot.”
