Frequently asked questions
Is a 0.045 inch wheel a thin 1mm cutting disc?
Close to it. 0.045 inch works out to about 1.1 mm, the thinnest wheel in this collection, so it is the one to pick if you want a thin 1mm cutting disc. The 0.045 inch wheels come in 4, 4-1/2, 5 and 6 inch diameters.
When should I use a 1/16 inch thick cut-off wheel?
Pick 1/16 inch (1.6 mm) when you want the thicker, stiffer wheel. Here it comes in 6 and 7 inch and is listed for mild and structural steel, stainless steel, cast iron, pipe, angle iron and sheet metal.
What size thin cutting disc fits my grinder?
Match the wheel diameter to your grinder, then match the centre hole to the spindle. Most wheels here have a 7/8 inch (22 mm) arbor, and the 4 inch wheels come with a 5/8 inch (16 mm) or 3/8 inch (10 mm) hole. Check the maximum RPM marked on the wheel and never exceed it.
Can a 1mm grinder disc be used for grinding?
No. Every wheel in this collection is listed for cutting only. For grinding, switch to a grinding wheel or a flap disc.
