Robert Sorby ProEdge Zirconium Belt – 120 grit
Our ProEdge zirconium belt 120 grit is the belt to reach for when you want a working edge back without reshaping the tool. Zirconium fractures as it wears, exposing fresh cutting grain instead of glazing over, so it keeps working long after aluminium oxide has given up.
What the zirconium belt 120 grit is for
Everyday sharpening for high speed steel turning tools. It takes enough steel to bring a tired gouge or scraper straight back to a cutting edge, but not so much that you lose the profile you have spent time getting right. For most turners this is the belt that lives on the machine. Robert Sorby make these in Sheffield to the same 775mm x 50mm size as every other belt in the range.
Where it sits in the range
- Zirconium belt 60 grit — reprofiling, damage repair and reshaping a bevel from scratch.
- Zirconium belt 120 grit — the everyday sharpening belt for high speed steel turning tools.
- Aluminium oxide 240 grit — refining the bevel on carbon steel chisels and plane irons.
- Trizact 600 and finer — honing to a polished edge.
Fitting the zirconium belt 120 grit
775mm x 50mm, the standard ProEdge size, so it fits every ProEdge and ProEdge Deluxe machine. Run it dry. The belt speed carries the heat away from the tool, which is the whole point of a linisher over a dry grinder, though a light hand still gives the cleanest result. Abrasive belts are consumables and are not covered by the Sorby lifetime guarantee.
Shipping and pickup
Belts ship Australia-wide via Australia Post. Pickup is welcome from our Mulgrave NSW store, Monday to Friday 9am to 4pm and Saturday 9am to 12pm.
