SHREDDER ceramic flap discs with a 4-1/2-inch diameter, 5/8-11 threaded hub and Type 29 angled profile. Choose 36, 40, 60, 80 or 120 grit for stock removal, weld grinding, deburring and blending in compatible metalworking applications.
Check the hub before choosing a disc
The 5/8-11 designation describes the mounting thread. It is different from a plain 7/8-inch arbor hole. Confirm the grinder’s approved thread, disc diameter, guard and mounting arrangement, and compare the disc’s marked maximum speed with the tool’s speed. Follow the disc and tool instructions.
Which grit should I choose?
Use 36 or 40 grit when the job calls for coarser material removal. Compare 60 or 80 grit for blending and refinement, and 120 grit for finer scratch refinement. Test on the same material and start with the least aggressive grit that completes the work. A grit number does not guarantee a final finish.
What does Type 29 mean?
Type 29 describes an angled flap-disc profile. Type 27 has a flat profile. Choose the profile and working angle specified for your task and tool; neither type is universally better for every surface.
Is this the same as a hook-and-loop sanding disc?
No. This flap disc mounts to a compatible angle grinder through its threaded hub. A hook-and-loop or PSA sanding disc attaches to a matching backing pad on a compatible sander. The mounting systems are not interchangeable.

Compare the exact options before ordering
This is the 5/8-11 threaded-hub SHREDDER disc. The hub specification is a mounting thread, not a 5/8-inch plain arbor hole. Confirm the grinder’s approved mounting system before ordering.

Which SHREDDER mounting style do you need?
A 7/8-inch arbor hole and a 5/8-11 threaded hub are different mounting systems. Use the disc, guard and mounting hardware specified for your grinder. The disc’s marked maximum speed must meet or exceed the tool’s speed; do not infer an RPM rating from diameter alone.
Ceramic sanding disc or ceramic flap disc?
SAVAGE discs attach to a matching sander backing pad with hook-and-loop or PSA. SHREDDER flap discs have overlapping abrasive flaps and a Type 29 profile for compatible angle-grinder work such as weld grinding and blending. Choose by the tool’s mounting system and the job, not by ceramic grain alone.
