Norton 66252842204 Type 29 Grinding Wheel 4.5in 36 Grit

Product Description

The NORTON 66252842204 is a Type 29 depressed center grinding wheel designed for aggressive material removal on metals and weld grinding applications. At 4.5 inches in diameter and 0.125 inches thick, this wheel uses an aluminum oxide abrasive bonded with a resinoid bond for durability under load. The 36-grit medium grade delivers fast, coarse stock removal suitable for fabrication shops, weld dressing, and surface conditioning tasks. It mounts via a 7/8-inch arbor hole and is installed by welders, fabricators, and metalworkers using standard right-angle grinders.

This wheel is suited for use on ferrous metals, structural steel, and weld beads in both shop and field environments. The Type 29 conical profile increases the contact angle with flat and contoured surfaces compared to a flat Type 27 wheel, making it effective for blending and feathering in addition to heavy grinding. Typical applications include weld removal, deburring, and surface preparation prior to coating or inspection. It is sold individually but carries a minimum order quantity of 25 units, making it appropriate for shop stocking and fleet-scale tool supply.

Key Features

• Type 29 depressed center profile for aggressive contact angle on flat and contoured surfaces
• Aluminum oxide abrasive for consistent performance on ferrous metals and steel
• 36-grit medium grade for fast, coarse stock removal and weld grinding
• Resinoid bond for durability and resistance to fracture under grinding pressure
• 7/8-inch arbor hole fits standard right-angle grinder spindles
• Lightweight at 0.1 pounds per wheel for reduced operator fatigue during extended use

Compatibility

Designed as an OEM-style replacement and standard consumable for right-angle grinders accepting a 7/8-inch arbor and 4.5-inch diameter Type 29 depressed center wheels.

Installation Notes

This wheel is installed by fabricators and metalworkers on right-angle grinders rated for the wheel diameter and RPM. Always confirm the grinder's maximum RPM rating meets or exceeds the wheel's rated speed before mounting. Power down and unplug or lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before each use and discard any damaged wheel immediately.
