Quick-Change Disc for Aggressive Material Removal

The 3M 22396 361F disc uses a TR quick-change system to fit compatible sanders. Each brown disc is 1-1/2 inches in diameter and rated for 20,000 RPM maximum speed. The pack contains 50 coated abrasive discs.

Suited for Heavy Stock Removal on Metal

These extra-coarse 36 grit aluminum oxide discs handle rapid material removal on ferrous and non-ferrous metals. The polyester YF-weight backing resists heat during sustained grinding. They are not suited for fine finishing, wood sanding, or applications requiring a smoother surface profile.

36 Grit Capacity with 50-Disc Supply

The closed-coat aluminum oxide grain cuts aggressively through welds, scale, and heavy corrosion. The YF polyester backing provides durability for high-pressure grinding. The 50-piece pack supports extended production runs before reordering. Discs wear quickly on hardened steels or when used beyond the rated speed limit.

Questions about this item

Do I need a TR quick-change back-up pad for the 1-1/2 in disc?

Yes, the disc uses a TR quick-change system and must be mounted on a compatible 1-1/2 in back-up pad before use.

Will the 20,000 RPM maximum speed work with my older rotary sander?

Only if the sander's no-load speed is 20,000 RPM or lower; exceeding that limit can cause the disc to fail.

How can I confirm the 361F disc is cutting correctly after fitting it?

The aluminum-oxide grit should produce a consistent scratch pattern and remove material evenly without glazing or excessive heat buildup.
