Diamond Hole Saws – Usage Instructions for Guidance only

Cooling and Lubrication

When cutting hard materials it is important to ensure the cutter is kept cool to avoid damage to the material being drilled and premature wear of the cutter

Water is an ideal coolant and a constant supply will need to be applied to the tool during use

This can be achieved by running water over the hole during use or by using a small hose

The harder the material the more lubrication/coolant will be needed

Usage

Ideally the cutter should be used in a drill stand or purpose made drilling machine however it is also possible to produce good results using the technique below – especially for smaller drill sizes.

The workpiece should be firmly clamped to avoid movement

Holding the drill firmly drilling should start at an angle of 45 degrees until the hole has started and then the drilling should continue at 90 degrees to the surface

We recommend that you practice on a piece of waste material

An alternative method especially useful for larger holes is to clamp a template to the work

The template can be used to start the hole and avoid the drill moving around

Templates can be made using the drill itself on a piece of scrap plywood or similar.

Please ensure that safety precautions are taken during use - especially eye protection.
