Norton 66252906092 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66252906092 is a Type 1 straight surface grinding wheel designed for precision stock removal on hard carbon steels, soft carbon steels, and tool steels. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond, rated at a coarse grade with a grit size of 46 and an H hardness code. Rated for a maximum of 3600 RPM, this wheel suits surface grinders and cylindrical grinders in both production and tool-room environments. The specification code is 32AA46-HVTRP.

This wheel is suited for surface grinding operations on hard and soft carbon steels and tool steels. It is commonly used in tool rooms, maintenance shops, and production grinding cells. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse 46-grit cut rate makes it effective for aggressive material removal passes where surface finish is secondary to stock removal rate.

Key Features

• Type 1 straight wheel profile — no recess, no taper
• 46-grit aluminum oxide abrasive for coarse, fast material removal
• Vitrified bond provides rigidity and consistent cut characteristics
• H hardness (soft rating) allows the wheel to release dull grains and resist loading on hard steels
• 3600 RPM maximum speed rating
• Blue wheel color consistent with NORTON 32A series identification

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for material applications including hard carbon steels, soft carbon steels, and tool steels as specified by the manufacturer.

Installation Notes

Wheel mounting and dressing should be performed by a qualified grinding machine operator or machinist following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
