Steel cutting discs for angle grinders and chop saws, mainly Bosch Professional, with Makita and DeWalt wheels for specific machines. These are the abrasive discs that fabricators, welders, fencers and plumbers buy by the box: 115 mm and 125 mm thin discs for the small grinder, 230 mm discs for the big one, and 355 mm wheels for the cut-off saw.
Choosing a steel cutting disc
- 115 mm or 125 mm: the everyday sizes for 4.5" and 5" grinders. Both run a 22.23 mm bore.
- 230 mm cutting disc: for 9" grinders cutting angle iron, rebar and heavy tube. Stocked in 2.5 mm and 3 mm thicknesses.
- Thickness: 1 mm and 1.6 mm discs cut quickly with a narrow kerf and little heat; 2.5 mm and 3 mm discs are slower but tougher on thick section and last longer.
- Inox discs: made without iron, sulphur or chlorine fillers so they do not leave contamination on stainless steel. Use them on anything you will weld or that needs to stay rust-free.
- Chop saw wheels: 355 mm Bosch Expert Metal and Makita wheels, plus a 405 mm Makita wheel, for bench cut-off saws.
Metal cutting disc prices and which to buy
A cutting disc price is driven by thickness and the grade of abrasive. The Bosch Standard for Metal discs are the value option for everyday steel; the Expert line costs more per disc but cuts more metres before it is used up. The Multi-Construction discs cut steel, brick and tile when you are changing materials on site. The small 76 mm discs are for the DeWalt DCS438 and Bosch GWS 12V-76 cordless cut-off tools.
