Grier Abrasives A11-GB-13883 Mounted Point 60 Grit

Product Description

The GRIER ABRASIVES A11-GB-13883 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Shaped as a pointed tree (A11 profile), it delivers targeted abrasive action in die grinders and rotary tools. At 60 grit medium grade with a hard density rating, it removes material efficiently while maintaining shape under load. The vitrified bond holds abrasive grains firmly, making this point well suited for consistent stock removal on metal surfaces. Licensed tradespeople and toolroom machinists are the typical end users for this type of abrasive tooling.

This mounted point is used in metalworking, fabrication, and maintenance applications where internal grinding, cavity work, or contour finishing is required. The A11 pointed tree profile allows access to grooves, ports, and recessed surfaces that flat or cylindrical wheels cannot reach. It is commonly used on steel, cast iron, and other ferrous metals in both production and repair environments. The 0.25 inch shank diameter fits standard collet-equipped die grinders and rotary tools found in industrial and shop settings.

Key Features

• A11 pointed tree profile for access to contoured and recessed surfaces
• 60 grit medium grade for efficient material removal with moderate surface finish
• Aluminum oxide abrasive with vitrified bond for durable, consistent cutting action
• Hard density rating maintains wheel shape under steady grinding pressure
• 0.25 inch shank diameter fits standard die grinder collets
• Rated to 19,860 RPM maximum for safe use in high-speed rotary tools

Compatibility

Designed as a direct-fit mounted point for die grinders and rotary tools accepting a 0.25 inch shank diameter collet.

Installation Notes

Installation and use of mounted abrasive points should be performed by qualified machinists or toolroom personnel familiar with abrasive safety standards. Before mounting, ensure the tool spindle is fully stopped and the power source is isolated. Never exceed the maximum rated RPM of 19,860 as marked; verify the tool speed rating before use. Inspect the mounted point for cracks or damage before each use and discard any point showing visible defects.
