Norton 66243494107 Surface Grinding Wheel 46 Grit 7in

Product Description

The NORTON 66243494107 is a Type 1 surface grinding wheel built for aggressive stock removal on a wide range of metals. It measures 7 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. The abrasive is aluminum oxide bonded with a vitrified bond system, rated at 46 grit coarse grade with an H hardness code, placing it in the soft-to-medium hardness range. Rated to a maximum of 3600 RPM, this wheel suits production grinding environments where consistent cut rate and wheel life must be balanced. The series designation is 32A46-HVS3. It weighs 1.3 pounds and the wheel color is gray.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in shop and production settings. Typical applications include flat surface finishing and stock removal on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46-grit cut makes it best suited for rough passes where material removal rate takes priority over final finish. It is a non-tapered, non-recessed straight wheel appropriate for standard surface grinding setups.

Key Features

• Aluminum oxide abrasive for broad metal compatibility including stainless, carbon steels, and cast iron
• Vitrified bond construction for rigidity and consistent grain exposure during grinding
• 46 grit coarse grade for high material removal rates on rough passes
• H hardness code, soft-to-medium rating, allows wheel to self-dress effectively on harder workpieces
• 3600 RPM maximum speed rating for standard surface grinder spindle use
• Porous wheel structure promotes coolant flow and reduces heat buildup at the grind zone

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machine operator or toolroom technician familiar with ANSI B11.9 and OSHA 1910.215 requirements. 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 for this wheel.
