Keeping the drill bit on target

Most of the diamond-coated drill bits – hole saws are manufactured without a pilot drill bit.  People who are used the pilot drill bits from wood – plastic hole saws, may think of this as a missing component but it is actually done on purpose. Because pilot drill bits will crack glass – tile – granite, etc.

 

We specifically do not have the pilots because a) pilots get dull before the hole saw b) pilots have a tendency to crack some materials like glass

To help to start the hole, we have a guide. Click to read reviews on Amazon.

You have to have a way to keep the drill bit on target. Here are some methods:

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.

 If you have one of our sets that come with the PU case and insert, the inserts can also serve as a guide to start the hole.

Here is what one of customers said about our guide:

I was anxious about drilling into my granite countertop. The Drilax guide was easy to size to my 1 1/2" diamond hole saw. I located the hole position & locked the guide into place. Once I began drilling, I felt totally at ease that the hole saw would not skip about. Huge success, remarkable value. My confidence in accurately cutting through granite, marble or tile is very high using this guide.”
