Diamond grinding heads are used primarily by individuals and companies manufacturing glass leadlights.

The grinding heads are used to produce glass shapes that cannot be easily produced by other glass cutting methods.  Grinding expensive stained glass is also cost effective, as the risk of breakage is reduced.

We apply a high concentration of evenly distributed diamond.

Following computer aided machining of the solid brass body our grinding heads are hand made.

Our manufacturing processes ensure excellent bond strength between the diamond, the matrix material and the brass body.

The locking screw is stainless steel (so it won't rust), we also supply a hexagonal locking key.

We use only top quality virgin industrial diamond.  IDP grinding heads will suit all commonly available machines that have a 5/16" diameter spindle.

The 6mm (1/4") and 3mm (1/8") diameter tools are manufactured complete so there is no need of an adaptor.

IDP grinding heads are well made diamond tools that will almost certainly cut better, last longer and cost less than what you're currently using.

Our prices are wholesale ex factory.  Whether you purchase one or two tools for your own use, or larger quantities and on-sell them, our prices remain the same.

We have supplied thousands of grinding heads to customers in Australia and New Zealand since the start of volume manufacturing well over 10 years ago.

The only complaint in all that time was one tool that was a tight fit on the machine spindle!

Finally, have you had problems with new tools that just don't cut very well, or had the diamond layer lift away after little use?  You may have taken them back to the shop and complained only to be told that it's your fault or that they are all like that!  We've heard the stories time and again.

So far as we are concerned, if the Diamond layer comes away from the brass or steel body in pieces, while the tool is being used in a proper manner, it's almost certainly a manufacturing problem, and the tool would be replaced!

The long term solution is easy, buy one of our Grinding Heads (we don't mind if you buy one at a time) try it, and then let us know what you think.
