Cratex 40028 Surface Grinding Wheel 80 Grit Type 1

Product Description

The CRATEX 40028 is a Type 1 surface grinding wheel designed for precision material removal on a range of metallic and non-metallic workpieces. Measuring 2 inches in diameter and 1/4 inch thick with a 1/4 inch arbor hole, this wheel is built around an aluminum oxide abrasive grain rated at 80 grit, placing it in the medium grade range. It carries a maximum operating speed of 18,145 RPM. The compact form factor suits bench grinders, die grinders, and similar tooling used in fabrication shops, maintenance facilities, and light industrial applications. Licensed tradespeople and skilled technicians working on deburring, surface prep, or material blending operations will find this wheel straightforward to mount and run.

This wheel is suited for surface grinding tasks that require a controlled, medium-grit cut on ferrous metals, castings, and similar substrates. Its small diameter and standard Type 1 straight-wheel profile make it compatible with handheld grinder setups and bench-mounted units with a 1/4 inch spindle. Typical use cases include weld dressing, edge cleanup, and general-purpose stock removal in shop environments. No recess geometry means the wheel mounts flush against standard arbor flanges without requiring specialty hardware.

Installation Notes

Grinding wheel installation should be performed by a qualified technician following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always disconnect or de-energize the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test on vitrified wheels. Never exceed the marked maximum RPM of the wheel or the rated speed of the machine, whichever is lower.
