What it is
The DeWalt DT43908-QZ OSA cutting disc is a high-performance consumable for large-diameter angle grinders, measuring 180 mm with a thickness of 1.6 mm. The larger size makes it suited to work requiring greater depth and cutting capacity than smaller-diameter discs.
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.
