Norton 66253044184 Surface Grinding Wheel 60 Grit 8 in

Product Description

The NORTON 66253044184 is a Type 1 surface grinding wheel engineered for precision stock removal on soft carbon steels, tool steels, and super alloys. It measures 8 inches in diameter and 3/4 inches thick with a 1-1/4 inch arbor hole. The abrasive is white aluminum oxide bonded with a vitrified bond, producing a medium-grade, semi-friable wheel rated to a maximum of 3600 RPM. The wheel carries a hardness code of I and the manufacturer specification 38A60-IVBE. Machinists and grinding technicians rely on this construction for consistent surface finish and controlled wheel breakdown during heavy-duty surface grinding operations.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. Its aluminum oxide abrasive and vitrified bond make it a dependable choice for applications requiring a balance of cut rate and wheel life when working soft carbon steels, tool steels, and super alloys. The non-tapered, non-recessed flat wheel profile fits standard surface grinder spindle setups.

Key Features

• Type 1 flat wheel profile — no recess, no taper — fits standard spindle arbors
• White aluminum oxide abrasive for controlled, semi-friable cutting action on ferrous and alloy materials
• Vitrified bond provides rigidity and consistent grain exposure throughout wheel life
• 60 grit, medium grade (hardness code I) balances stock removal with surface finish quality
• 3600 RPM maximum rated speed for safe operation on compatible machines
• Specification 38A60-IVBE identifies this wheel within the Norton 38A Type 1 series

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. Fits spindles accepting a 1-1/4 inch arbor hole.

Installation Notes

Grinding wheel installation must be performed by a qualified machinist or grinding technician following ANSI B11.9 and manufacturer safe-handling guidelines. Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum speed of 3600 RPM. Use proper flanges and blotters as required by the grinder manufacturer.
