First to our loyal business to business customers:

Due to the current situation, Coventry Grinders have decided to take Government advice and close down our business for a 3-4 week period as from today.

We will of course be able to work from home quoting and liaising with yourselves as normal – please feel free to keep in contact and ask any question you may need answers to

Unfortunately we will not be able to work on your orders right now, however the situation is fluid and will assess things as the days and weeks progress and supply customers as and when possible – please bear with us


Secondly, our online/website customers:

You will be able to purchase through the webshop but we cannot guarantee at present when these will be shipped as they may not be shipped until we return.

***Please bear this in mind before you purchase ***


Thank you all for your custom and stay safe.

Coventry Grinders CG3 Ceramic Grinding Wheel * VIDEO*

In the below video we show the performance of our own brand of ceramic grinding wheel made with Norton ceramic grain on a hard material. Test piece is hardened D2 tool steel (1.2379) hardened to 62 deg Rockwell C. Wheel specification is a 46 grit K hardness. Ceramic likes pressure to perform at its optimum.

We demonstrate on a Jones & Shipman 540 Surface grinder, We used this machine as its the most popular machine found in toolrooms in the UK. We show a 0.002″, 0.003″ and then a 0.005″ feed rate. Used a single point diamond with a rough dress.

The wheel performs extremely well, cool cutting on dry grinding. We stock a comprehensive range of Ceramic wheels from internal, external, Surface and cylindrical in various grit sizes.
