Norton 66253160163 Surface Grinding Wheel 60 Grit

Product Description

The NORTON 66253160163 is a Type 1 vitrified surface grinding wheel engineered for precision stock removal on a range of ferrous workpiece materials. The wheel measures 10 inches in diameter and 0.75 inches thick, with a 3-inch arbor hole. Constructed from semi-friable aluminum oxide abrasive, it carries a 60-grit rating and an I hardness code, placing it in the medium grade range. The vitrified bond provides rigid grain support and consistent cutting action, making this wheel a reliable choice for surface, cylindrical, and CNC tool-machine grinding operations.

This grinding wheel is suited for use on soft carbon steels, tool steels, and super alloys. It is designed for installation on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production shop and maintenance environments. The 38A Type 1 series designation indicates the specific abrasive formulation and wheel geometry. Non-porous construction and a non-tapered, flat profile support accurate, repeatable stock removal across a variety of industrial grinding applications.

Key Features

• 60-grit, I hardness (medium grade) aluminum oxide abrasive for controlled material removal
• Semi-friable grain structure promotes self-sharpening action during use
• Vitrified bond delivers rigid support and consistent cut rate
• Type 1 flat wheel profile with no recess and no taper
• Maximum rated speed of 2,485 RPM
• White wheel color for easy visual identification of this abrasive series

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys per the 38A Type 1 series specification (38A60-IVBE).

Installation Notes

Grinding wheel installation should be performed by a qualified operator following ANSI B11.9 and applicable shop safety standards. Before mounting, power down and lock out the grinder completely. Always ring-test the wheel for cracks before installation and verify the machine's rated speed meets or exceeds the wheel's 2,485 RPM maximum. Never exceed the marked maximum RPM, and use the correct flange size and blotters as specified by the machine manufacturer.
