Value Collection 81548257 Diamond Surface Grinding Wheel

Product Description

The VALUE COLLECTION 81548257 is a Type 1A1 diamond surface grinding wheel designed for precision material removal on hard and brittle workpieces. At 8 inches in diameter, 1/2 inch thick, and bored to a 1-1/4 inch arbor hole, this wheel fits standard surface grinding machine spindles. The 150 grit rating places it in the very fine grade range, making it suitable for finishing passes and tight-tolerance work where surface finish quality matters as much as stock removal. The 1/8 inch superabrasive depth provides the diamond layer thickness needed for extended wheel life under moderate grinding loads. Machinists and tool and die professionals typically select this wheel for ceramics, carbide, glass, and hardened steel applications.

This wheel is used in surface grinding operations found in machine shops, tool rooms, and precision manufacturing environments. The Type 1A1 form factor is a straight wheel profile, the most common geometry for reciprocating surface grinders. It suits both wet and dry grinding setups depending on the workpiece material and machine capability. The very fine 150 grit makes it a finishing wheel rather than a roughing tool, appropriate for final passes where dimensional accuracy and low surface roughness are the primary goals.

Key Features

• Type 1A1 straight wheel geometry fits standard surface grinder spindle arbors
• 150 grit very fine grade for finishing cuts and low-roughness surface results
• Diamond abrasive construction suited for hard and brittle materials including carbide and ceramics
• 1/8 inch superabrasive depth for extended usable wheel life
• 1-1/4 inch arbor bore accommodates common surface grinding machine spindle sizes

Compatibility

Designed as an OEM-style replacement or direct-use diamond surface grinding wheel for Type 1A1 surface grinder applications requiring a 8 inch diameter wheel with a 1-1/4 inch arbor bore.

Installation Notes

Surface grinding wheels must be installed by qualified machine operators familiar with abrasive wheel safety per ANSI B7.1 standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test; never mount a damaged wheel. Confirm spindle speed does not exceed the maximum RPM rating for this wheel diameter before operation.
