Tru-maxx RESIN-7 Cbn Grinding Wheel 120 Grit Type 11V9

Product Description

The TRU-MAXX RESIN-7 is a cubic boron nitride (CBN) grinding wheel designed for precision tool grinding and sharpening applications. Built to Type 11V9 geometry, this resinoid-bonded wheel operates at 120 grit with a fine grade, making it well-suited for finishing and reconditioning high-speed steel and carbide cutting tools. The wheel measures 3.75 inches in diameter and 1.5 inches in overall thickness with a 1.25-inch bore. A superabrasive depth of 0.0625 inches and 100 concentration rating indicate a dense, consistent abrasive layer capable of sustained material removal under controlled conditions. It supports both wet and dry operation, giving the operator flexibility based on machine setup and coolant availability.

This wheel is used in tool rooms, production grinding environments, and maintenance shops where cutting tools require accurate edge restoration. Typical applications include grinding drill bits, end mills, reamers, and similar high-speed steel or hardened tool steel cutters. The Type 11V9 cup-wheel profile is specifically engineered for clearance-angle grinding on fluted tools. Both wet and dry operation modes make it adaptable to bench grinders and dedicated tool-and-cutter grinder setups found in industrial and trade environments.

Key Features

• Cubic Boron Nitride (CBN) superabrasive for high hardness and long wheel life on ferrous tool steels
• Type 11V9 cup-wheel geometry suited for clearance and face grinding of cutting tools
• Resinoid bond provides controlled cut and consistent finish at 120 grit fine grade
• Supports both wet and dry operation for compatibility with a range of grinder setups
• 100 concentration superabrasive layer for uniform stock removal across the wheel face
• 1.25-inch bore fits standard tool-and-cutter grinder spindle configurations

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for tool-and-cutter grinders accepting a Type 11V9 cup wheel with a 3.75-inch diameter and 1.25-inch bore.

Installation Notes

Mounting and dressing of CBN grinding wheels should be performed by a qualified machinist or tool-room technician familiar with abrasive wheel safety. Before mounting, power down and lock out the grinder per OSHA and machine manufacturer lockout-tagout procedures. Inspect the wheel for cracks or chips before installation and never exceed the rated maximum operating speed marked on the wheel. Use appropriate flanges and a proper arbor fit to the 1.25-inch bore; do not force the wheel onto an undersized or oversized spindle.
