2-inch Type 27 Flap Disc
This Norton BlueFire R884P flap disc measures 2 inches in diameter and carries a P80 coarse grit. It is built for metalworkers who need aggressive stock removal on a right-angle grinder. The zirconia alumina grain cuts fast on steel and stainless steel. The semi-open cotton backing resists loading during extended grinding sessions.
TR Quick-Change Mounting
The disc uses a TR threaded-hole quick-change system that locks onto a compatible backing pad in seconds. No tools are required beyond the grinder spindle. A common error is overtightening the disc, which can distort the plastic backing plate and cause vibration. Always confirm the grinder runs at or below 30,000 RPM before starting.
Sustained Grinding Performance
Under continuous load the zirconia alumina grain fractures to expose fresh cutting edges, keeping material removal steady. The semi-open coating and Y-weight cotton backing shed swarf to reduce heat buildup on the workpiece. The disc maintains consistent cut rate until the flaps wear to the backing plate.

Questions about this item
How do I confirm the disc runs safely at its rated speed after mounting?
Check that the angle grinder spindle reaches no more than 30,000 RPM and that the disc sits flat on the Type 27 backing plate without wobble during a brief test run.
What comes in the package and what must I supply separately?
The box contains the 2 in BlueFire R884P flap disc with TR threaded hole; you must provide a compatible angle grinder or quick-change holder that accepts the TR system.
Which grit and diameter should I choose for coarse stock removal on metal?
Select the 2 in diameter with P80 grit — this combination matches the listed BlueFire R884P specification for aggressive material removal.
