The grey coloured spectrum wheels are essentially one step down from the red range of wheels. Offering increased flexibility which allows them to access the more difficult lines of the tubular fillet welds on hand rails and pipe work.
Designed primarily for Stainless Steel (Inox) fillet welds they can also be used to refine the scratches left after using a coated abrasive product such as a fibre disc or flap disc. This makes them perfect for finishing stainless steels used in the food and medical industries.
If there is a size of spectrum wheel you require for your fillet weld grinder that you cannot see online, just give us a call.
