Cratex 40062 Surface Grinding Wheel 54 Grit Aluminum Oxide

Product Description

The CRATEX 40062 is a Type 1 surface grinding wheel designed for material removal and surface finishing on metalworking and industrial applications. It measures 2 inches in diameter and 1/4 inches thick, with a 1/4 inches arbor hole for secure mounting on compatible spindles and grinders. The abrasive grain is aluminum oxide at a coarse 54 grit, suited for aggressive stock removal on ferrous metals and similar hard materials. Rated at a maximum of 27,120 RPM, this wheel is sized for use on die grinders, rotary tools, and small bench grinders. It carries a hard hardness rating for extended wheel life under consistent pressure.

This wheel fits typical light-duty precision and bench grinding applications where a small-diameter, straight-profile wheel is required. It is well suited for deburring, sharpening, and surface conditioning tasks in machine shops, maintenance facilities, and fabrication environments. The compact 2-inch diameter makes it appropriate for tight-clearance work or use in handheld rotary tools. It is sold individually and is intended for professional tradespeople and machinists who require a reliable, spec-consistent abrasive wheel.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive wheel safety standards, including ANSI B7.1 guidelines. Always inspect the wheel for cracks or chips before mounting and perform a ring test where applicable. Ensure the spindle speed does not exceed the wheel maximum RPM rating of 27,120 before operation. Power down and disconnect the tool from its energy source before mounting or removing the wheel.
