CBN, PCD, MCD & CVD CUSTOM TOOLS

Tools designed from new, modified or made to your specification!

Tools Designed From New, Modified or Made to Your Specification

Special CBN, PCD, CVD & MCD cutting tools for drilling, milling, reaming, turning, grooving and forming.

Our German partner JBO are one of Europe’s leading manufacturers of special cutting tools with brazed CBN, PCD, CVD or MCD cutting edges. From design planning with customers and selection of optimal cutting materials for specific applications, to the production using the latest generatio laser grinding machines, JBO produce special cutting tools with the hardest, most accurate and razor sharp cutting edge which is characterised by minimal micro chipping and cutting edge wear.

We also work with a UK manufacturer who can offer PCD and CBN special tools at excellent prices and fast delivery for applications that have a smaller budget.

Superhard Cutting Materials

We know that speed of delivery is so important to customers, we will ensure your enquiry is sent to our most trusted manufacturers to ensure we can achieve the best delivery time for you.

PCD - Polycrystalline Diamond

Best for Aluminium, Abrasive Plastics and Carbon Fibre.

PCD is an artificially manufactured industrial diamond. However, PCD differs significantly from MKD in its crystal structure, because this is not monocrystalline (single-grained) but polycrystalline (multi-grained).

Special PCD cutting tools can be produced for drilling, milling, reaming, turning, grooving and forming.

CVD - Chemical Vapour Deposition Diamond

Best for the most Abrasive materials including, Glass Filled Plastics, Aramid and Carbon Fibre where tool life and maintaining a sharp cutting edge is the main priority.


CVD Diamonds (CVD-D) are diamonds which are produced by the chemical vapor deposition process (i.e. they are grown from a ‘seed’). The advantage compared to PCD is higher diamond purity (99% diamond content) & vastly increased wear resistance. It is ideal for applications with the most abrasive materials such as glass filled re-enforced plastics. Special CVD cutting tools can be produced for drilling, milling, reaming, turning, grooving and forming.

MCD - Monocrystalline Diamond

Ideal for machining non-ferrous metals or plastics such as acrylic where a mirror glass finish is required and polishing can be eliminated.


MCD is an artificially manufactured industrial (single-grained) diamond. It’s single grain structure enables the machining of materials to produce the highest quality mirror finish possible with any cutting tool. Special MCD cutting tools can be produced for routing, drilling, milling, reaming, turning, grooving and forming.

CBN - Cubic Boron Nitride

Ideal for machining the hardest of materials and cast iron.


Cubic boron nitride (CBN) is a synthetically produced composite cutting material and has around half the hardness of a diamond. It is particularly suitable for machining high hardened steels above HRc60 where extreme tool life and perfect surface roughness is required. Special CBN cutting tools can be produced for drilling, milling, reaming, turning, grooving and forming
