Sanding Disc Selection
Use sanding discs and accessories that are:
• correct size as written on tool's nameplate.
• rated at or above the RPM listed on the tool's name-
plate.
• correct accessory, wheel type and grit for the job.
Select the correct type of sanding disc for your job.
Generally, use 24 or 36 grit for heavy stock removal;
50, 60, or 80 grit for medium stock removal and 120
grit for finishing. Always begin with a coarse grit, us-
ing successively finer grits to obtain the desired finish.
•Aluminum Oxide: For fast cutting, general purpose
discs for most metal jobs. Best for cold-rolled steel,
stainless steel or metals requiring tough, fast cutting,
long lasting abrasives.
•Aluminum Zirconia Bi-Cut: Unique grit pattern is
arranged in clusters for faster stock removal and
cleaning. Ideal for removing paint from cars, boats,
etc. without clogging.
•Ceramic: Lasts up to 3 times longer than Aluminum
Oxide Discs. For general metal working. Ideal for
tough jobs.
