Tru-maxx 66253291616 Mounted Point 60 Grit B114

Product Description

The TRU-MAXX 66253291616 is an aluminum oxide mounted point in an inverted cone radius end (B114) shape, designed for precision grinding, deburring, and surface finishing on ferrous and non-ferrous metals. At 60 grit with a medium grade, it removes material efficiently while leaving a controlled surface finish. The 1/8 inch shank diameter fits standard die grinders and rotary tools, and the 1-1/2 inch shank length provides adequate reach for recessed or contoured workpiece surfaces. Weighing just 0.02 pounds, this mounted point is a consumable abrasive used by machinists, fabricators, maintenance technicians, and tool-and-die professionals.

This mounted point suits applications including weld blending, port work, mold and die finishing, and general deburring in both shop and field environments. The medium-grade aluminum oxide abrasive is well matched for grinding carbon steel, alloy steel, and cast iron. It is commonly used in maintenance and repair operations (MRO), light manufacturing, and metalworking trades where controlled stock removal in tight or irregular geometries is required. The inverted cone radius end profile allows the grinding face to access internal radii and chamfers that flat or cylindrical wheels cannot reach.

Key Features

• B114 inverted cone radius end shape for access to contoured and recessed surfaces
• 60 grit aluminum oxide abrasive for medium stock removal and controlled surface finish
• 1/8 inch shank diameter fits standard die grinder collets and rotary tool chucks
• Rated to 75,840 RPM maximum for compatibility with high-speed rotary tools
• Pink aluminum oxide grain provides consistent cut rate on ferrous metals
• Lightweight at 0.02 pounds — minimal mass addition to the tool spindle

Compatibility

Designed for use in die grinders, flexible shaft machines, and rotary tools fitted with a 1/8 inch collet. Suitable as an OEM-style replacement or standard consumable wherever B114-profile mounted points are specified.

Installation Notes

Mounted points must be installed in a collet that matches the shank diameter exactly — do not use an adapter that allows radial play. Before mounting, inspect the point for cracks, chips, or bond irregularities and discard any damaged piece. Always run the tool at or below the rated maximum RPM; exceeding the rated speed is a safety hazard. Wear appropriate eye protection and a face shield when operating any bonded abrasive product.
