 Customized Service for Rock Hard Felt Wheel:

The normal size for this item is 250mm diameter X 45mm thickness X 12mm arbor hole, and the density is 0.65g/cm³. Other sizes and densities can be customized. If you have special demands on this item, please feel free to contact us. The general lead time is 20 days for the customized felt wheels.

The density of The Rock Hard Felt Wheel:

To get the best results, the density of the felt wheel must be rock hard or flint hard. If the density just “soft”, “medium”, and “hard”, it will round the knife edges and reduce the knife sharpness. The normal density we supply is 0.65g/cm³, rock hard. If you want the higher density rock hard felt wheel, please email us and let us know your requirements. The max density is 0.80g/cm³.

How to Use The Rock Hard Felt Wheel:

For best results, the rock hard felt wheel needs to use with the diamond spray together. The diamond spray must be alcohol-based or oil-based, the alcohol-based is the best. Please don’t use the water-based diamond spray on the felt wheels. Due to the special production process and the material of the felt wheel, the felt wheel might be expanded or deformed after us with water-based diamond spray.

The recommended grit of the diamond sprays is 0.5μm, 1μm, 3μm, and 6μm.

To change to use of a fine grit diamond spray, you will have to remove a 0.1mm thickness from the felt wheel. Since after using one diamond spray, some abrasive and steel powder will keep on the felt wheel and will affect the next finer grit operating. Experience told us, that the grit 80# sandpaper is a fine choice for grinding the outside surface of the felt wheel.

Maintenance of The Rock Hard Felt Wheel:

During the sharpening process, if you find the felt wheel turns black and the sharpening effectiveness goes down. Please use the 80# grit sandpaper to clean your felt wheel.

Please take down your rock hard felt wheel from your Tormek machine for a long time unused. And keep the wheel in a non-humid environment to avoid dampness.

Always tighten the wheel and keep the careful operation during the sharpening process.

We also supply rock hard double-taper felt knife sharpening wheels.
