Norton 66252835361 Surface Grinding Wheel 80 Grit 6 in

Product Description

The NORTON 66252835361 is a Type 1 straight surface grinding wheel designed for precision material removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal and controlled surface finishes across a range of workpiece materials. The wheel measures 6 inches in diameter by 1/8 inches thick with a 1-1/4 inches arbor hole, rated to a maximum of 4140 RPM. At 80 grit and K hardness (medium grade), it is suited for moderate material removal where a balance of cut rate and surface quality is required. Licensed trades and precision grinding shops rely on this wheel for reliable performance on surface and cylindrical grinding machines.

This wheel is appropriate for surface grinding applications on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is compatible with CNC cutting tool machines, cylindrical grinders, and surface grinders. The 1/8 inches thickness makes it a narrow-profile wheel suited for slotting, form grinding, or fine stock removal passes where a full-width wheel would be excessive.

Key Features

• Aluminum oxide abrasive for broad material compatibility across ferrous and non-ferrous workpieces
• Vitrified bond provides rigidity, porosity, and consistent wheel breakdown during grinding
• 80 grit, K hardness (medium grade) balances cut rate with surface finish quality
• Porous wheel structure aids coolant retention and chip clearance during wet or dry grinding
• Type 1 straight wheel profile fits standard surface grinder and cylindrical grinder spindles
• 4140 RPM maximum speed rating for safe operation on compatible machines

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 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 maintenance technician familiar with ANSI B11.9 grinding machine safety standards. Always power down and lock out the grinder before mounting or changing wheels. Inspect the wheel for cracks or chips before installation and perform a ring test per manufacturer guidelines. Never exceed the wheel's rated maximum RPM as marked on the blotter or wheel itself.
