Norton 66252941330 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 66252941330 is a Type 1 surface grinding wheel engineered for precision material removal on soft carbon steels, tool steels, and super alloys. Built from aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent stock removal and a predictable wear pattern across surface and cylindrical grinding operations. It measures 7 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. The 60-grit, medium-grade construction balances cut rate with surface finish, and the H hardness code keeps the wheel from loading prematurely on softer work materials. Rated at 3600 RPM maximum, it suits both wet grinding setups and standard production cycles.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production or job-shop environments. The 38A Type 1 series is a standard configuration commonly found in tool rooms and metalworking shops handling a range of ferrous materials. Its porous, semi-friable structure promotes cool cutting, which is particularly relevant when working with heat-sensitive tool steels and super alloys. Licensed machinists, tool and die makers, and grinding machine operators are the primary installers and operators of this wheel.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled cut on ferrous metals
• 60-grit medium grade balances material removal rate with surface finish quality
• H hardness code and semi-friable grain resist loading on soft carbon steels
• Porous wheel structure promotes cool cutting and reduces thermal damage to workpiece
• Type 1 flat wheel profile fits standard surface and cylindrical grinder arbors
• Rated for wet grinding operations, compatible with coolant-fed machine setups

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Recommended material applications include soft carbon steels, tool steels, and super alloys. Specification code 38A60-HVBEP identifies this wheel within the NORTON 38A Type 1 series.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machine operator or toolroom technician following applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and lock out the machine before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips before installation and perform a ring test prior to use. Never exceed the maximum rated RPM of 3600 under any operating condition.
