7" X 1/8" X 5/8"-11 T27 Pipeline Wheel - 10 Pack

Benchmark Abrasives 7" x 1/8" x 5/8"-11 T27 pipeline wheels are built for demanding fabrication and pipe work where operators need both cutting and light grinding from the same wheel. The larger 7" diameter provides greater reach and cutting depth for pipe, structural steel, weldments, fabricated assemblies, and field repair applications where smaller wheels may not provide enough access.

Made with aluminum oxide abrasive grain, the 1/8" Type 27 depressed-center construction gives the wheel enough body for combination-duty work without moving into a full 1/4" grinding-wheel profile. It is designed for steel, stainless steel, and other approved metals, allowing operators to cut through the workpiece and then perform light edge cleanup, bevel work, or weld refinement without immediately changing abrasives.

The 5/8"-11 threaded hub mounts directly onto compatible 7" angle grinders using a 5/8"-11 spindle. With a maximum speed of 8,600 RPM, this wheel provides a convenient hubbed option for cutting and light grinding when the machine is specifically approved for 7" bonded abrasive wheels and the proper guard is used for the operation.

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 cutting and light-grinding applications.

Compatible examples include:

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

Do not use this 7" wheel on 4-1/2" or 5" grinders simply because they also use a 5/8"-11 spindle. The grinder must be specifically approved for a 7" wheel diameter.

Match the 7" diameter and 5/8"-11 spindle thread. Follow the hubbed-wheel mounting instructions, check full thread engagement and guard clearance, and use the guard specified for cutting or light grinding. Other models may also be compatible when they meet the same wheel and setup requirements.

Cutting & Grinding Performance

The 1/8" pipeline profile is specifically designed for cutting and light grinding, giving fabricators more versatility than a thin cutting-only wheel. Operators can make the cut and then perform light edge, bevel, or weld cleanup with the same wheel.

The 7" diameter provides additional reach for larger pipe and structural applications, while the threaded hub simplifies wheel installation compared with a plain-arbor mounting setup.

For aggressive or sustained stock removal, use a dedicated Type 27 grinding wheel rather than treating this pipeline wheel as a heavy-grinding wheel.

Safety Tips

• This wheel is approved for cutting and light grinding.
• Do not use it as a substitute for a dedicated heavy-grinding wheel.
• Never exceed the wheel's 8,600 RPM maximum speed.
• Use only on machines specifically approved for 7" bonded abrasive wheels.
• Confirm the grinder uses a compatible 5/8"-11 spindle.
• Always use the proper guard for the wheel shape and operation.
• Make sure the threaded hub is fully and correctly engaged before use.
• Inspect the wheel before use and do not operate cracked, chipped, damaged, or improperly stored wheels.
• Maintain control during cutting and avoid excessive twisting or side loading.
• Wear appropriate eye and face protection, hearing protection, gloves, and other PPE required for the application.
