A metal cutting disc is a thin reinforced-resin abrasive disc that cuts steel, stainless steel, aluminium, rebar and sections with an angle grinder or cut-off saw.
What it is for
Used for cutting metal sections, sheet and tube.
How to use it
Check that the diameter, bore and maximum speed match the machine, and fit it with the correct flanges and the guard in position. Cut with the disc perpendicular to the workpiece, which is clamped in a vice, without bending the disc or using its side for grinding. Use a dedicated stainless steel or aluminium disc where required, and discard any disc that is chipped or past its printed expiry date.
