Tool Accessories

Check two things: the disc diameter and the bore size in the centre. Both must match your grinder and its guard. Also check the maximum speed on the disc is higher than your grinder's no-load speed. The listing gives these specs.

Wood bits have a sharp centre point, metal bits are usually HSS steel with a plain point, and masonry bits have a carbide tip for brick and concrete. Use hammer mode only with masonry bits. The listing says which materials each bit or set is made for.

Replacement batteries are listed with the model numbers and tool range they are made to fit, such as 18V lithium packs. Match the voltage and slide-on fitting to your tools and charger. If your tool or charger model is not listed, check with the manufacturer before ordering.

Electric tool sharpeners in the range are designed for drill bits, knives, scissors, chisels and planer blades, using different guides and slots for each. Check the listing for the drill bit sizes and blade types it handles, and take light passes so you do not overheat the edge.

Use coarse grit, around 40 to 80, to strip paint or shape timber, medium grit, around 100 to 150, to smooth, and fine grit, 180 and above, before painting or oiling. Work through the grits in order. Make sure the disc or sheet size and fitting suit your sander.

It varies by set. Each listing gives the number of pieces and the sizes included. Larger sets cover more sizes and sometimes mix wood, metal and masonry bits. Choose a set that covers the sizes you use most rather than the biggest piece count.
