Tru-maxx RESIN-42 Type 11V9 Diamond Grinding Wheel 5 in 120G

Product Description

The TRU-MAXX RESIN-42 is a Type 11V9 superabrasive grinding wheel engineered for precision material removal on hard and difficult-to-grind workpieces. It uses Armored Synthetic Diamond (ASD) abrasive bonded in a resinoid matrix, delivering consistent stock removal with a fine 120-grit finish. The wheel measures 5 inches in diameter and 1.75 inches overall thickness with a 0.125-inch superabrasive depth and an abrasive concentration rating of 75. It is rated for both wet and dry operation, giving tool-room machinists and grinding technicians flexibility in coolant use. The 70-degree face angle suits profile and cup-wheel grinding applications where controlled contact geometry is required.

This wheel is suited for tool and cutter grinding, carbide tooling reconditioning, and precision surface work in both production and tool-room environments. The resinoid bond provides a degree of compliance that helps reduce heat buildup and surface burn on heat-sensitive materials. Its fine 120-grit rating makes it appropriate for finish-grinding passes rather than aggressive stock removal. The wheel accepts a 1.25-inch arbor hole, fitting a wide range of bench, pedestal, and dedicated tool-and-cutter grinding machines. Both wet and dry operating modes are supported, making it adaptable to shops with or without coolant delivery systems.

Key Features

• Armored Synthetic Diamond (ASD) superabrasive rated at 75 concentration for consistent cutting action
• Resinoid bond provides compliance and helps manage heat at the grinding interface
• 120-grit fine grade suited for finish and light stock-removal passes
• Dual wet and dry operation compatibility
• 0.125-inch superabrasive depth delivers extended usable wheel life

Compatibility

Designed as an OEM-style replacement or direct-fit superabrasive grinding wheel for tool-and-cutter grinders accepting a 1.25-inch arbor hole and a 5-inch diameter Type 11V9 cup wheel.

Installation Notes

Installation and dressing of superabrasive wheels should be performed by qualified tool-room machinists or grinding technicians familiar with ANSI B11.9 grinding machine safety standards. Always de-energize and lock out the grinder before mounting or removing the wheel. Inspect the wheel for visible damage or cracks before each use and never exceed the rated operating speed marked on the wheel. When switching between wet and dry operation, verify that coolant lines are fully purged or shut off as applicable before starting the spindle.
