Bristle Disc for Right-Angle Grinders
The Scotch-Brite 24243 is a 4.5 inch bristle disc built for right-angle grinders with a 5/8 inch -11 threaded hole. It suits metalworkers and fabricators who need consistent surface preparation on aluminium, brass, bronze, cast iron, stainless steel and steel.
12,000 RPM Maximum Operating Speed
The disc is rated for a maximum of 12,000 RPM, so it must only be used on grinders that do not exceed this speed. Exceeding the limit risks bristle failure and unsafe operation, making the speed rating the primary constraint for tool selection.
P120 Grit with 3/4 Inch Trim for Surface Blending
The P120 ceramic bristles and 3/4 inch trim length provide aggressive cutting action for blending, deburring and finishing on the listed metals. The fixed grit and trim mean the disc cannot reach finer finishes or tighter profiles without changing to a different specification.

Questions about this item
Should I choose the 120 grit or a different grade for cleaning aluminium and stainless steel?
The 120 grit ceramic bristles are designed for aluminium, brass, bronze, cast iron, stainless steel and steel, giving a consistent finish on those metals.
What does the 12,000 RPM maximum speed mean when the disc is mounted on my right-angle grinder?
It is the highest safe operating speed; running the disc faster can cause bristle failure, so keep the grinder at or below 12,000 RPM.
Will the 5/8-11 threaded hole fit my grinder's spindle?
Yes, the 5/8 In.-11 threaded hole matches the standard spindle on most right-angle grinders for direct mounting.
