Norton 66253043353 Surface Grinding Wheel 8in 80 Grit

Product Description

The NORTON 66253043353 is a Type 1 surface grinding wheel engineered for aggressive stock removal on hard ferrous metals and high-performance alloys. Built on a vitrified bond with a semi-friable ceramic abrasive grain, it carries an 80 grit medium grade for efficient cutting action with consistent surface finish. The wheel measures 8 inches in diameter, 1/4 inch thick, and features a 1-1/4 inch arbor hole. Rated to 3600 RPM, it is designed for use in production and maintenance grinding applications performed by machinists and tool room technicians.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications across both job shop and production environments. Material applications include 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Its ceramic grain construction handles the elevated cutting temperatures common when working heat-sensitive alloys and hardened tool steels without excessive grain breakdown.

Key Features

• Ceramic abrasive grain with semi-friable structure for sharp, cool cutting on hard alloys
• Vitrified bond provides rigidity and dimensional stability during high-precision surface grinding
• 80 grit medium grade balances stock removal rate with acceptable surface finish
• K hardness code with medium wheel hardness rating resists glazing on harder workpiece materials
• Porous wheel structure promotes coolant flow and chip clearance
• Type 1 straight wheel profile with no recess, compatible with standard surface and cylindrical grinder spindles

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron workpieces. Series designation is 5SG Type 1 with internal specification code 5SG80-KVS.

Installation Notes

Installation should be performed by a qualified machinist or tool room technician following the grinder manufacturer's mounting procedures and ANSI B11.9 safety standards for abrasive wheels. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and perform a ring test per ANSI standards. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
