11V9C 125mm Flared Cup Wheel

This is our recommended wheel for HSS and carbide end mill ends and flutes. The wheel is flared, compared to the CMS-30 and 31, allowing for more complex operations such as end gash.

CBN versus Diamond

Choose CBN for high speed steel (HSS) tools and diamond for carbide tools.  CBN and diamond have similar hardness.  A key difference is that diamond grit media is composed of carbon which can interact chemically with the carbon in your steel tool when grinding at high speeds and temperatures.

Grit

The lower grits are recommended for most end mill end and flute grinding. If a finer finish is desired choose a higher grit

Diameter

We recommend the 4″ Flared Cup Wheel for basic tool grinders like the old CUTTERMASTERS (FCG-30, MG-30, CM-01) and our modern basic tool grinders (CM-01DC, JX). The smaller diameter gives better clearance in tight areas.

The 5″ cup wheel is recommended when position isn’t limited by the basic tool grinders. So if you are using the CM-Riser or have a tool grinder with height adjustment the 5″ Flared cup is preferable.

This braked wheel truer is all you need to keep your resin bond wheels shaped and ready for precision grinding. All of our wheels come equipped with a dressing stick to keep the grit media proud and sharp, as well. This production support package consists of two wheels and a wheel truing device. This kit will have you set up for HSS and carbide end mill ends, flutes and rads.
