Cratex 74-2 M Surface Grinding Wheel Rubber Bond Medium

Product Description

The CRATEX 74-2 M is a small-diameter surface grinding wheel designed for precision material removal on fine, close-tolerance workpieces. It measures 0.875 inches in diameter, 0.125 inches thick, with a 0.125-inch arbor hole, and is built on a rubber bond with a medium grade abrasive structure. The rubber bond provides a degree of flex and vibration dampening not found in vitrified wheels, making it well suited for finish grinding on delicate or intricate parts. Rated at 25,000 RPM, this wheel is intended for high-speed rotary tools and spindle-driven precision equipment. Installation and operation are typically handled by machinists, tool and die makers, jewelers, and electronics technicians.

This wheel is sized for fine, detail-oriented grinding applications across a wide range of industries. Common use cases include deburring, blending, and surface finishing on aerospace components, electronic parts, instruments, jewelry, dies, molds, light castings, plastic articles, and super sensitive scientific devices. Its compact diameter and rubber bond construction make it a practical choice where conventional abrasive wheels would be too aggressive or too rigid for the workpiece geometry involved.

Key Features

• Compact 0.875-inch diameter with 0.125-inch arbor hole fits standard precision tool spindles
• Brown wheel color consistent with CRATEX rubber-bonded abrasive product line
• Suited for non-ferrous, ferrous, and engineered material workpieces in precision trades

Compatibility

Designed for use with aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super sensitive scientific devices. Fits rotary tools and precision spindles accepting a 0.125-inch arbor.

Installation Notes

This wheel is installed by machinists and precision tooling technicians using rotary tools or spindle-driven grinding equipment. Always verify that the tool spindle speed does not exceed the 25,000 RPM maximum rating before mounting. Power down and de-energize all equipment before changing or seating the wheel. Inspect the wheel for cracks or chips prior to each use and never force the wheel onto an arbor that does not match the 0.125-inch hole size.
