Norton 66253149572 Surface Grinding Wheel 80 Grit

Product Description

The NORTON 66253149572 is a Type 1 surface grinding wheel engineered for precision material removal on a range of ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and profile retention across extended grinding cycles. It measures 10 inches in diameter, 1/4 inches thick, and accepts a 3-inch arbor hole. The 80-grit, K-hardness (medium grade) specification targets applications where controlled surface finish and dimensional accuracy are required. The semi-friable aluminum oxide grain self-sharpens under load, reducing heat buildup at the workpiece surface. Rated at a maximum of 2,485 RPM, this wheel is well-suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.

This grinding wheel is designed for use on soft carbon steels, tool steels, and super alloys. Its medium hardness and 80-grit structure make it appropriate for general surface grinding where moderate material removal and reasonable surface finish are both priorities. The 3-inch center hole fits standard surface grinder spindles, and the Type 1 straight-wheel profile suits flat surface and cylindrical OD grinding operations in production and tool room environments alike. The white aluminum oxide wheel color indicates a friability level suited to heat-sensitive workpieces.

Key Features

• Aluminum oxide abrasive with semi-friable grain for self-sharpening under load
• Vitrified bond provides rigidity and consistent form-holding during grinding
• 80 grit, K hardness (medium grade) balances stock removal with surface finish quality
• Type 1 straight-wheel profile fits surface grinders, cylindrical grinders, and CNC tool machines
• Non-tapered, no-recess design for straightforward mounting on standard 3-inch arbors
• Series 38A Type 1 specification (38A80-KVBE) for consistent grade-to-grade repeatability

Compatibility

Rated 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 with a 3-inch arbor bore.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding specialist in accordance with ANSI B11.9 and applicable shop safety standards. Always power down and de-energize the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips before each installation using the ring test, and never exceed the rated maximum of 2,485 RPM. Use proper flanges and blotters as recommended by the machine manufacturer.
