Stock Removal


The Norton Vulcan R842 was featured in our video ‘How to make a patio heater’.  It was used during the stock removal process to remove the burrs and to quickly tidy up the sharp edges on steel using grit 60. (The disc is a versatile product for rough grinding and de-burring on steel and stainless steel). It was also used in the scale and rust removal step before welding to avoid contamination and for a neat weld seam.
