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 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.

Our coating will not separate from 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 30 years ago, and have many satisfied customers.
