4-1/2" X 7/8" T27 FLAP DISC FOR ALUMINUM WITH STEARATE COATING - 1 PIECE
Built specifically for aluminum and other soft non-ferrous metals, this 4-1/2" T27 flap disc combines aggressive aluminum oxide abrasive with a specialized stearate coating that helps resist loading and gumming during grinding. Instead of allowing soft metal to pack between the abrasive grains and reduce cutting performance, the anti-loading coating helps keep the abrasive surface working more effectively as heat builds during use.
The flat T27 profile is especially well suited for shaped and non-flat workpieces such as aluminum tubing, frames, rails, posts, fabricated assemblies, edges, and similar components. Available in coarse 36 and 60 grit, this disc is designed for fast stock removal, weld cleanup, blending, deburring, and surface preparation on materials that can quickly load a conventional flap disc.
High Density/Jumbo construction adds more flaps and a thicker abrasive profile than a regular-density flap disc, giving the user more usable abrasive material for demanding fabrication work. Combined with an X-weight polycotton cloth backing and aluminum-specific anti-loading treatment, this disc is a strong choice for shops that regularly grind aluminum, copper, zinc, tin, and other soft non-ferrous metals.

Machine Compatibility
Designed for compatible 4-1/2" to 5" angle grinders using a 7/8" mounting system.
For a Benchmark option, use the Benchmark Abrasives 4-1/2" corded angle grinder, which supports compatible 7/8" bore accessories.
Because this is a High Density/Jumbo flap disc, always confirm sufficient guard, flange, and mounting-hardware clearance before operation. The grinder's operating speed must not exceed the flap disc's 13,300 RPM maximum.
Safety Tips
- Inspect the flap disc before use and do not use a damaged disc.
- Never exceed the maximum rated speed of 13,300 RPM.
- Use the proper grinder guard and compatible mounting hardware.
- Confirm adequate clearance for the thicker High Density/Jumbo construction.
-
- Secure the workpiece and maintain control of the grinder throughout use.
- Use only on grinders approved for the disc diameter and mounting configuration.
- Dry use only.
