Norton 66253364342 Surface Grinding Wheel 14in 60 Grit

Product Description

The NORTON 66253364342 is a Type 1 straight surface grinding wheel designed for precision material removal on ferrous and non-ferrous workpieces. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and a controlled finish across a wide range of metalworking applications. The 60 grit rating and K hardness code place it in the medium grade category, balancing cut rate with surface finish. At 14 inches in diameter, 1.5 inches thick, and 5 inches bore, it is sized for production surface grinding operations. Maximum rated speed is 1800 RPM. The wheel weighs 17.5 pounds and carries the specification designation 32A60-KVBE.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in industrial and tool room environments. Material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a standard production grinding wheel commonly installed by machinists and grinding machine operators in job shops and manufacturing facilities requiring consistent, repeatable material removal.

Key Features

• Aluminum oxide abrasive for broad metal compatibility including stainless, carbon steel, and cast iron
• Vitrified bond construction for rigidity and consistent wheel breakdown during use
• 60 grit, K hardness (medium grade) balances cut rate and finish quality
• Porous wheel structure promotes coolant retention and chip clearance
• Type 1 straight profile with no recess and non-tapered form for standard surface grinding setups
• Specification designation 32A60-KVBE for direct cross-reference and replacement sourcing

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped to accept a 14-inch diameter, 5-inch bore Type 1 grinding wheel rated at 1800 RPM or lower.

Installation Notes

Grinding wheel installation must be performed by a qualified machinist or grinding machine operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always power down and lock out the machine before mounting or dismounting the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the 1800 RPM maximum rated speed marked on the wheel.
