The 50 mm depressed-centre metal grinding wheel A80 is an abrasive wheel designed for light to medium-duty metal grinding, deburring and weld preparation. It is a 50 mm diameter, depressed-centre (dep.centre) wheel made from aluminium oxide abrasive with an A80 grit size. The depressed-centre head profile allows secure clamping between flanges and gives improved access to edges and contours compared with a straight wheel.

Technically, the wheel is a resin-bonded aluminium oxide (A) abrasive, grit 80, offering a balance between stock removal and surface finish when working on carbon steel, alloy steel and stainless steel. It is manufactured to the bonded abrasives safety requirements of EN 12413. Thread type is not applicable to this accessory; head type is depressed-centre and drive type is dependent on the host tool (fits grinders using the correct flange and guard configuration). Always check that the wheel bore and flange arrangement match your grinder and that you do not exceed the tool’s rated speed.

Typical applications include weld beveling and seam grinding, removal of surface weld spatter, edge blending, general-purpose metal shaping and finishing in small workshops or on-site maintenance work. Common users are metal fabricators, welding contractors, automotive repair shops, maintenance engineers and hobbyists working with hand-held or bench grinders. The A80 grit is particularly useful where a finer finish is needed after coarse grit passes or where moderate material removal is required without aggressive scratching.

Key benefits of this wheel are the abrasion properties of aluminium oxide for ferrous metals, a resin bond that resists glazing and wheel loading, and the depressed-centre profile which improves operator control and access. The wheel provides consistent cutting performance on steel types and good life in typical grinding tasks, while compliance with EN 12413 ensures safety expectations for bonded abrasives are met. For safe use, always employ appropriate guards, flanges and personal protective equipment.
