Norton 66252841913 Type 27 Depressed Center Wheel 46 Grit

Product Description

The NORTON 66252841913 is a Type 27 depressed center grinding and cutting wheel designed for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive and a resinoid bond, this wheel delivers consistent cut rates across ferrous metals. At 4.5 inches in diameter and 0.045 inches thick, it falls into the thin cutoff category, suited for tight clearance cuts and precise scoring passes. The medium-grade, 46-grit construction balances cut speed with surface control. Licensed tradespeople and metalworkers use this wheel with angle grinders equipped with a 5/8-11 threaded spindle for tasks ranging from structural steel cutting to pipe notching.

This wheel is a standard fit for 4.5-inch angle grinders used in industrial, commercial, and light fabrication settings. The Type 27 raised-hub profile allows improved clearance at lower grinding angles, making it practical for flat and flush-cut applications. It is commonly used by pipefitters, ironworkers, welders, and maintenance mechanics who need a reliable consumable cutoff wheel for daily production work. The minimum order quantity is 10 units, sold individually by package.

Key Features

Compatibility

Designed as an OEM-style replacement consumable for 4.5-inch Type 27 angle grinders with a 5/8-11 threaded spindle arbor.

Installation Notes

Installation of grinding and cutoff wheels must be performed by qualified personnel following ANSI B7.1 safety standards. Inspect the wheel for cracks or chips before mounting and never exceed the wheel's rated maximum RPM. Power down and disconnect the grinder from its power source before changing wheels. Use the correct flange and locking nut for a Type 27 wheel and ensure the guard is in place before operation.
