Frequently Asked Questions

What is this and how do I use it?

A coated abrasive disc or wheel.

Refer to the product name for the specific type and attachment method.

What grit do I need?

Match the grit to the job: 40 to 60 grit for ultra-coarse rapid stock removal; 80 to 120 grit for general work; 150 to 240 grit for fine finishing.

Lower grit numbers cut faster but leave a rougher finish; higher grit numbers cut slower but finish smoother. For paint removal, start coarse (40 to 60). For surface preparation before painting or coating, finish at 120 to 180. For polishing metal, work up through several grits.

What material does this work on?

Designed for steel and stainless steel as standard. Aluminium, brass and timber can also be worked but use a dedicated wood-grit disc on timber for the best finish.

Stainless requires zirconia or ceramic-grain coated abrasives (most BNA SKUs) to avoid loading and overheating. Aluminium and brass work with the same disc but with light pressure to avoid clogging the abrasive.

Where are these typically used?

Refer to the product description for the typical application.

How to Measure

Measurements Accurate to the relevant standard and should be used as a guide only. They are either hand-measured or taken from suppliers' catalogues. Stock is sourced from various suppliers, so differences may exist between batches in markings, appearance or finish.
