Tru-maxx 66253291579 Mounted Point B91 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253291579 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface blending in metalworking and fabrication applications. It features a B91 flat cone point shape, 60 grit abrasive, and a medium grade that delivers consistent stock removal on ferrous and non-ferrous metals. The shank measures 1/8 inch in diameter and 1-1/2 inches in length, seating securely in die grinders and rotary tools. Rated to a maximum of 61,110 RPM, this mounted point is built for controlled, high-speed work in tight cavities and contoured surfaces where larger abrasive wheels cannot reach.

This mounted point is suited for tool and die work, weld blending, mold finishing, and general metal fabrication in both shop and field settings. The flat cone geometry of the B91 profile makes it effective on inside radii, slots, and angled surfaces. It is typically used by machinists, fabricators, and maintenance technicians working with die grinders, rotary tools, or flexible shaft machines. The aluminum oxide abrasive performs well on carbon steel, alloy steel, and hard cast materials.

Key Features

• B91 flat cone point shape for access to inside radii, slots, and contoured surfaces
• 60 grit, medium grade aluminum oxide abrasive for efficient stock removal
• 1/8 inch shank diameter fits standard die grinders and rotary tools
• 1-1/2 inch shank length provides reach into deep cavities
• Maximum rated speed of 61,110 RPM for high-speed grinding applications
• Blue color coding for quick grit and grade identification

Compatibility

Designed for use with die grinders, rotary tools, and flexible shaft machines fitted with a 1/8 inch collet or chuck. Suitable for grinding and finishing operations on ferrous metals, alloy steels, and hard cast materials.

Installation Notes

This mounted point is installed and serviced by machinists, fabricators, or maintenance technicians using standard die grinders or rotary tools. Before mounting, confirm the tool is unplugged or the air supply is disconnected and that the collet or chuck is sized to accept a 1/8 inch shank. Never exceed the maximum rated RPM of 61,110 as marked on the product or packaging. Inspect the mounted point for chips or cracks before each use and discard any damaged abrasive immediately.
