Tru-maxx 66253291661 B45 Mounted Point 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253291661 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in metalworking and fabrication applications. This B45 pointed-shape abrasive is 5/16 inches thick with a 1/8 inches shank diameter and a 1-1/2 inches shank length, making it compatible with standard rotary tools and die grinders. Rated at a maximum of 79,600 RPM, it runs at a medium grade with 60 grit — a general-purpose cut suited to stock removal and moderate surface blending on steel and ferrous metals. The pink aluminum oxide construction delivers consistent cutting action with predictable wear characteristics.

This mounted point fits into typical die grinder, rotary tool, and tool post grinder setups used in metal fabrication shops, maintenance and repair operations, and toolroom environments. Its B45 pointed profile allows access to confined areas, internal bores, slots, and contoured surfaces where flat or cylindrical wheels cannot reach. Machinists, tool and die makers, and maintenance technicians commonly use this type of abrasive for cleanup work on castings, weld seam dressing, and edge conditioning on ferrous workpieces.

Key Features

• B45 pointed shape provides access to tight radii, internal bores, and contoured surfaces
• 60 grit medium grade balances stock removal with surface finish quality
• Aluminum oxide abrasive material is well-suited for grinding ferrous metals and steel
• Maximum rated speed of 79,600 RPM for use with standard die grinders and rotary tools
• 1/8 inches shank diameter fits common collet sizes on handheld and bench-mounted rotary equipment
• Lightweight at 0.02 pounds for reduced operator fatigue in extended use

Compatibility

Designed for use with die grinders, rotary tools, and similar equipment accepting a 1/8 inches shank diameter collet. Verify that the tool spindle speed does not exceed the 79,600 RPM maximum rating before use.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive tooling and rotary equipment. Before mounting, confirm the tool is unplugged or the pneumatic supply is disconnected and depressurized. Insert the shank fully into the collet and tighten securely according to the tool manufacturer's collet torque guidance. Never operate this mounted point above its marked maximum RPM, and always wear appropriate eye and face protection per ANSI B7.1 standards.
