Description

Diamond coated hole saws are perfect for drilling holes in glass, marble, tile, granite and other very hard materials. These are good for bathroom projects where you have to mount mirrors and the like on top of tiles.

Each holesaw has a 3.2mm shank (1/8"), meaning they can be used in all rotary tools including Dremel, Ryobi, Fuller, Ozito, GMC and other generic brands that have a 3.2mm collet (which is 99% of rotary tools).

CONTENTS OF SET

DRILLING TIPS
1. Wet cutting is best. It reduces the amount of dust, flushes out the slurry so cuts a lot quicker and greatly extends the tool life by cooling the cutting edge. Use a spray bottle to keep them wet or drill the item slightly submerged in a large container. If that's not possible then use plasticine or Blu-tac to make a well around the hole and fill with water.
2. If you MUST dry cut then drill 5 seconds and rest 10 seconds to avoid overheating.
3. Never use hammer action it is less effective and the holesaw may be damaged.
4. Use a plywood template for cutting. You can secure the template to whatever you are cutting to ensure that it doesn't move from side to side. This is a very safe way to cut tiles or glass.
