Tru-maxx RESIN-30 Diamond Grinding Wheel 180 Grit Type 11V9

Product Description

The TRU-MAXX RESIN-30 is a Type 11V9 diamond grinding wheel designed for precision grinding applications requiring a very fine surface finish. Built with synthetic diamond (SD) abrasive and a resinoid bond at 100 concentration, this wheel delivers consistent material removal on hard or brittle workpieces. The cup-style Type 11V9 profile features a 70-degree face angle and a 1/8-inch superabrasive depth, making it well-suited for contour and surface grinding tasks. At 180 grit, it falls in the very fine grade range, ideal for finishing passes rather than aggressive stock removal. Licensed tradespeople and skilled machinists install and operate this wheel on compatible bench or pedestal grinders.

This wheel is commonly used in tool and cutter grinding, carbide tooling reconditioning, ceramic component finishing, and precision surface work in machine shops and industrial maintenance environments. Its wet and dry operation capability adds flexibility across different machine setups. The 3.75-inch diameter and 1.25-inch arbor hole fit standard tool and cutter grinder spindle configurations. Applications span both production grinding and one-off precision finishing work where surface quality is the priority over removal rate.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with abrasive wheel mounting procedures. Power down and lockout the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 guidelines. Never exceed the wheel's rated maximum operating speed, and always use the appropriate flanges and blotters during mounting.
