What it is
The DeWalt DT43942-QZ Extreme bonded cutting disc is an abrasive for angle grinders, 180 mm in diameter with a depressed-centre profile, as indicated by the designation 180x3,0x22,23mm. The larger size combined with the depressed-centre geometry makes it suited to cuts through substantial sections. The pack contains a single piece.
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.
