Norton 66252940095 Type 28 7in 24 Grit Grinding Wheel

Product Description

The NORTON 66252940095 is a Type 28 depressed center grinding wheel designed for aggressive material removal on angle grinders. Built with aluminum oxide abrasive in a very coarse 24 grit rating, this wheel cuts through weld beads, scale, and base metal quickly. The resinoid bond holds the abrasive securely at operating speeds up to 8,600 RPM. At 7 inches in diameter and 1/4 inch thick, it fits standard angle grinders with a 7/8 inch arbor. Licensed tradespeople in fabrication, pipefitting, ironwork, and general metalworking rely on this wheel for heavy stock removal and surface prep. The unit weighs 0.9 pounds.

This wheel is suited for use on ferrous metals where rapid material removal is the priority. The Type 28 profile provides a flatter grinding angle compared to a Type 27, improving surface contact and control during aggressive passes on flat or mildly contoured workpieces. Typical applications include weld removal, deburring, and surface conditioning in industrial, construction, and fabrication environments. The 24 grit aluminum oxide construction is rated for very coarse stock removal and is not intended for finishing passes.

Key Features

• Type 28 depressed center profile for improved surface contact at low grinding angles
• 24 grit aluminum oxide abrasive rated Very Coarse for fast stock removal
• Resinoid bond construction for durability at high operating speeds
• Maximum rated speed of 8,600 RPM for safe use on compatible angle grinders
• 7/8 inch arbor hole with arbor connector type fits standard angle grinder spindles
• Weighs 0.9 pounds for a balance of mass and maneuverability

Compatibility

Designed for use with angle grinders equipped with a 7/8 inch arbor. Confirm that the grinder's rated no-load RPM does not exceed the wheel's 8,600 RPM maximum before mounting.

Installation Notes

Always power down and unplug or lock out the angle grinder before mounting or removing a grinding wheel. Inspect the wheel for cracks or chips before each use and discard any damaged wheel immediately. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation. Follow ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels.
