Cratex 74 F Surface Grinding Wheel Silicon Carbide Fine

Product Description

The CRATEX 74 F is a small-diameter surface grinding wheel engineered for precision material removal on delicate and fine-tolerance workpieces. It measures 7/8 inches in diameter, 1/8 inches thick, and accepts a 1/16 inch arbor. The abrasive matrix combines silicon carbide grit with a rubber bond at a fine grade, producing a controlled, smooth cut that minimizes surface damage on sensitive substrates. Rated to 25,000 RPM, this wheel is suited for high-speed rotary tools and precision spindles. It ships in a package quantity of 100 units and is appropriate for machinists, toolmakers, jewelers, and electronic assembly technicians.

This grinding wheel is designed for fine finishing and deburring applications across a broad range of industries. Its small form factor and rubber bond construction make it particularly well-suited for work on aerospace components, dies, molds, electronic parts, instruments, jewelry, light castings, plastic articles, and super sensitive scientific devices. The silicon carbide abrasive cuts efficiently on non-ferrous metals and non-metallic materials, while the rubber bond provides cushioning that reduces the risk of workpiece damage in precision or close-tolerance finishing operations.

Key Features

• Silicon carbide abrasive for effective cutting on non-ferrous metals and non-metallic materials
• Rubber bond construction delivers cushioned, controlled material removal
• Fine grade abrasive minimizes surface roughness on precision workpieces
• 25,000 RPM maximum speed rating compatible with high-speed rotary and spindle tools
• No-recess design for straightforward mounting on standard arbors
• Compact 7/8 inch diameter allows access to tight geometries and small features

Compatibility

Intended for use with aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super sensitive scientific devices. Accepts a 1/16 inch arbor and fits rotary tools and precision spindles rated to accommodate a 25,000 RPM wheel.

Installation Notes

Mounting and operation should be performed by a qualified machinist or toolroom technician familiar with abrasive wheel safety. Ensure the tool or spindle is fully powered down and secured before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the 25,000 RPM maximum of this wheel before use, and inspect the wheel for cracks or chips before each session. Follow ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels.
