Grier Abrasives A5-B-19783 Mounted Point 36 Grit A5

Product Description

The GRIER ABRASIVES A5-B-19783 is an aluminum oxide mounted point in the A5 tree shape, designed for aggressive stock removal and surface finishing on metal, castings, and welds. It carries a 36 grit rating, placing it in the very coarse grade category, which makes it well suited for rapid material removal rather than fine finishing work. The resinoid bond holds the abrasive grain firmly under high-speed rotation, with a maximum rated speed of 45000 RPM. The 0.25 inch diameter shank fits standard die grinders and rotary tools used daily in fabrication, maintenance, and installation trades.

This mounted point is used in applications where a portable rotary tool needs to reach confined areas, contoured surfaces, ports, and weld joints. Typical install and service scenarios include deburring pipe ends, cleaning weld spatter in tight clearances, and prepping metal surfaces before fitting mechanical or electrical components. The overall length of 2.75 inches and the A5 tree profile allow access to recesses that flat or cylindrical wheels cannot reach. Licensed tradespeople in plumbing, HVAC fabrication, and general mechanical service regularly use this type of abrasive in daily maintenance work.

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.25 inch shank collet. Verify the tool spindle speed rating meets or exceeds the 45000 RPM maximum before mounting.

Installation Notes

Always confirm the die grinder or rotary tool is rated at or above the 45000 RPM maximum speed of this mounted point before use. Power down and disconnect the tool from its power source before installing or removing the point. Inspect the abrasive for cracks or chips before each use and do not use a damaged point. Eye protection and appropriate PPE are required when operating any abrasive mounted point.
