6" X 7/8" T27 HIGH DENSITY ZIRCONIA FLAP DISC - 1 PIECE
Built for demanding grinding jobs that benefit from a larger working surface and more abrasive capacity, this 6" T27 high density zirconia flap disc uses a true Jumbo construction with more flaps and a thicker profile than a regular-density flap disc. The added abrasive volume provides more usable grinding material, while the self-sharpening zirconia grain continually exposes fresh cutting edges under the heat and pressure of heavy metalworking.
The flat T27 profile is especially well suited for shaped and non-flat workpieces such as posts, gates, risers, tubing, edges, and larger fabricated assemblies. Its overlapping flaps provide the flexibility and surface control needed to grind, blend, deburr, and progressively refine irregular surfaces while the larger 6" diameter covers more area with each pass.
Benchmark Abrasives high density flap discs are built for users who need more abrasive capacity for repeated or higher-volume grinding work. The combination of true High Density/Jumbo construction, durable zirconia grain, X-weight polycotton cloth backing, and a larger 6" working diameter makes this disc a strong choice for fabrication shops, maintenance departments, and industrial metalworking applications.

Materials & Applications
Best For:
Carbon steel
Structural steel
Stainless steel
Cast iron
Additional Materials:
Titanium
Nickel
Wrought iron
Copper
Fiberglass
Plastic
Hard rubber
Wood
Stone
Common Applications:
Grinding and blending welds on shaped or non-flat surfaces
Posts, gates, risers, tubing, and larger fabricated assemblies
Heavy stock removal
Deburring and edge cleanup
Removing surface imperfections
Surface preparation
Larger-area fabrication work
Repeated maintenance and repair grinding
Machine Compatibility
Designed for compatible 6" angle grinders using a 7/8" mounting system.
Because High Density/Jumbo flap discs are thicker than regular-density discs, always verify sufficient guard and mounting clearance before operation. The grinder's operating speed must not exceed the flap disc's 10,200 RPM maximum.
Safety Tips
Inspect the flap disc before use and do not use a damaged disc.
Never exceed the maximum rated speed of 10,200 RPM.
Use only on a grinder approved for 6" accessories.
Confirm proper guard, flange, and mounting-hardware clearance for the thicker High Density construction.

Frequently Asked Questions
High Density and Jumbo refer to the same heavier flap-disc construction. This disc uses more flaps and has a thicker overall profile than a regular-density flap disc, providing more usable abrasive material.
The larger 6" diameter provides more working surface than smaller flap discs, making it useful for larger fabrication jobs and applications where covering more area with each pass is beneficial.
T27 flap discs have a flat face and are preferred by many users when grinding shaped or non-flat surfaces such as posts, gates, risers, tubing, edges, and similar fabricated components.
A T27 flap disc has a flat face and is generally preferred for shaped and non-flat surfaces. A T29 flap disc has an angled face that ergonomically approaches flat surfaces better, making T29 the preferred choice for flat grinding applications such as grinding down bead welds.
High Density flap discs are a strong choice for repeated or heavier grinding work where having more abrasive material in each disc is beneficial. Regular-density discs remain a good option for general grinding and blending where the thicker Jumbo construction is not necessary.
Zirconia is a durable, self-sharpening abrasive that performs well under the heat and pressure generated during demanding metal grinding. It is especially useful for heavier stock removal and fabrication work.
No. This is a 6" flap disc and should only be used on a grinder specifically approved for 6" accessories with the proper guard and mounting system. Examples include the Makita GA6020 and 9566CV and the Bosch GWS13-60P/GWS13-60PD. Use the correct 7/8" flange and 6" guard, and verify the grinder nameplate speed does not exceed 10,200 RPM.
Dry use only.
