Norton 66260273614 Surface Grinding Wheel 180 Grit

Product Description

The NORTON 66260273614 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding operations requiring a very fine finish. Built with synthetic diamond abrasive and a resinoid bond, this wheel delivers consistent cutting action and controlled material removal on hard, abrasion-resistant workpiece materials. The wheel measures 6 inches in diameter, 1/8 inch thick, with a 1-1/4 inch arbor hole. It carries a superabrasive concentration of 100 and a superabrasive depth of 1/4 inch, providing a substantial diamond layer for extended service life. Wet operation is recommended to manage heat and prolong wheel life.

This wheel is suited for surface grinding applications where improving workpiece finish is the primary goal. The 180 grit, very fine grade makes it appropriate for finish-grinding passes on hard ceramics, carbides, glass, and similar difficult-to-grind materials in tool rooms, precision grinding shops, and production grinding environments. It is typically mounted on surface grinders by skilled machinists or grinding technicians who require tight dimensional control and smooth surface finish.

Key Features

• Type 1A1 flat wheel geometry — straight-sided profile for conventional surface grinding
• Synthetic diamond (SD) abrasive at 100 concentration for consistent, long-lasting cutting performance
• 180 grit very fine grade for finish-grinding and surface improvement
• Resinoid bond provides controlled breakdown and free-cutting action
• Soft hardness rating (R) allows the wheel to self-dress effectively on hard workpieces
• Wet operation design helps dissipate heat and clear swarf during grinding

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for surface grinders accepting a Type 1A1 wheel with a 6-inch diameter and 1-1/4 inch arbor bore.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machinist or grinding technician following the grinder manufacturer's instructions and applicable ANSI B7.1 safety standards. Before mounting, power down and lock out the grinder, inspect the wheel for cracks or chips, and perform a ring test. Never exceed the wheel's rated maximum operating speed, and always install and torque the flanges and arbor nut according to the machine manufacturer's specification. Use proper coolant flow when operating in wet mode to prevent thermal damage to the workpiece and the diamond abrasive layer.
