7" x 1/4" x 5/8"-11 T27 Hub Depressed Center Grinding Wheel - 5 pack

7" X 1/4" X 5/8"-11 T27 HUB DEPRESSED CENTER GRINDING WHEEL - 5 PACK

Benchmark Abrasives 7" x 1/4" x 5/8"-11 T27 hub depressed center grinding wheels are built for aggressive stock removal, weld grinding, beveling, edge cleanup, and heavy fabrication work where a larger grinding surface and additional reach are valuable. The full 1/4" wheel thickness provides the wheel body needed for sustained grinding, while the 7" diameter gives operators more coverage on larger weldments, structural sections, and fabricated assemblies.

Made with aluminum oxide abrasive grain, these Type 27 wheels are designed for grinding steel, stainless steel, and other approved metals. The depressed-center profile provides practical working clearance for weld removal, surface cleanup, edge preparation, and material reduction across fabrication, maintenance, repair, and industrial applications.

The 5/8"-11 threaded hub mounts directly onto compatible 7" angle grinders with a 5/8"-11 spindle. With a maximum rating of 8,600 RPM, this wheel provides a convenient hubbed option for demanding grinding applications when the proper Type 27 guard and operating setup are used.

Bottom line, these cut off wheels offer LESS cutting resistance for fast work, LESS work piece waste, LESS vibration, LESS burrs and sparks and LESS dust than the competition.

Machine Compatibility

Designed for compatible 7" angle grinders with a 5/8"-11 spindle that are approved for Type 27 grinding wheels.

Compatible examples include:

• Makita® GA7031Y (8,500 RPM)
• Makita® GA7060 (8,500 RPM)
• Makita® GA7021 (6,600 RPM)
• Milwaukee® 2785-20 (6,600 RPM)

Use the proper Type 27 grinding guard and the manufacturer's 5/8"-11 hubbed-wheel mounting instructions. Check full thread engagement and guard coverage; do not clamp the threaded hub between plain-arbor wheel flanges. The grinder's maximum rated speed must not exceed 8,600 RPM. Other models may also be compatible when they meet the same wheel and setup requirements.

Do not install this wheel on a smaller grinder simply because the spindle thread matches.

Grinding Performance

The 7" diameter provides additional grinding surface and reach compared with smaller wheels, while the 1/4" profile gives the wheel the body needed for sustained material removal and weld grinding.

The 5/8"-11 threaded hub simplifies wheel installation and changes compared with a plain-arbor grinding wheel, making it a practical option for demanding shop and field applications.

This is a dedicated grinding wheel designed for weld removal, beveling, edge preparation, and stock reduction. Use it within the grinding angle and operating setup specified for the wheel and grinder.

Safety Tips

• Use this wheel for grinding applications.
• Never exceed the wheel's 8,600 RPM maximum speed.
• Use only on machines specifically approved for 7" Type 27 grinding wheels.
• Confirm the grinder uses a compatible 5/8"-11 spindle.
• Always use the proper Type 27 grinding guard specified for the grinder and wheel configuration.
• Make sure the threaded hub is fully and correctly engaged before operation.
• Use the grinder's side handle for control during grinding.
• Inspect the wheel before use and do not operate cracked, chipped, damaged, or improperly stored wheels.
• Avoid excessive pressure and allow the abrasive to perform the work.
• Wear appropriate eye and face protection, hearing protection, gloves, and other PPE required for the application.
