Cgw 54270 Ceramic Grinding Wheel 4.5x0.25x0.875 in T27 25/box

Product Description

The CGW 54270 is a Type 27 ceramic grain grinding wheel designed for aggressive stock removal on steel, stainless steel, and high-tensile metals. Measuring 4-1/2 x 1/4 x 7/8 inches with a 7/8-inch arbor bore, this wheel uses a high-density, uniform ceramic grain structure that is self-sharpening, delivering a cooler cut and extending wheel life compared to conventional abrasive wheels. The advanced bonding system features a dual-layer construction: an aggressive coarse ceramic grinding layer and a supporting layer that promotes surface finish consistency and smoother operation throughout the wheel's service life. Sold in boxes of 25.

This wheel is suited for heavy material removal in fabrication shops, structural steel work, pipe fitting, and general metalworking applications. Its high-performance ceramic grain excels on high-power angle grinders and is particularly effective where throughput and labor efficiency matter. Typical users include ironworkers, pipefitters, welders, and metal fabricators who need to maximize grind rate while reducing wheel changeover frequency. The 4-1/2-inch diameter fits standard 4-1/2-inch angle grinders widely used in the trade.

Key Features

• Ceramic grain construction delivers faster stock removal than conventional aluminum oxide wheels
• Self-sharpening, high-density grain structure produces a cooler cut and reduces workpiece heat buildup
• Dual-layer design: aggressive coarse grinding layer plus a supporting layer for improved surface finish
• Advanced bonding system engineered for longer wheel life and sustained fast grinding
• Compatible with steel, stainless steel, and high-tensile metals
• Optimized for use on high-power angle grinders and heavy material removal applications

Compatibility

Designed for use on standard 4-1/2-inch angle grinders with a 7/8-inch arbor. Suitable for grinding steel, stainless steel, and high-tensile metals. Type 27 depressed-center profile for flat and surface grinding applications.

Installation Notes

Mounting and use should be performed by qualified personnel following ANSI B7.1 safe use standards for abrasive wheels. Always inspect the wheel for cracks or damage before mounting, and never exceed the maximum RPM rating marked on the wheel. Ensure the grinder guard is in place before operation and wear appropriate PPE including face shield and gloves. Do not use a damaged or out-of-round wheel.
