Grier Abrasives W219-N4-17884 Mounted Point Cylinder W219

Product Description

The GRIER ABRASIVES W219-N4-17884 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface conditioning on metal and ferrous materials. Built with aluminum oxide grain and a unitized bond, this mounted point delivers consistent stock removal at a coarse grade. The shank diameter measures 0.25 inches with a shank length of 1.5 inches, making it compatible with standard die grinders and rotary tools. Rated to a maximum of 35,100 RPM, it is suited for high-speed applications where aggressive material removal is needed. At 0.04 pounds, it is lightweight and easy to handle during extended use.

This mounted point is used in metalworking, fabrication, and maintenance applications where controlled grinding in tight or contoured areas is required. It is appropriate for both shop and field use by machinists, tool-and-die workers, welders, and maintenance technicians working on castings, weld seams, ports, and similar surfaces. The W219 cylinder profile makes it effective for working inside bores, slots, and flat-bottom recesses where flat or tapered profiles would be less effective.

Key Features

• Cylinder W219 point shape for grinding bores, slots, and flat-bottom recesses
• Aluminum oxide abrasive grain suited for ferrous metals and hard alloys
• Coarse grade for aggressive stock removal and deburring
• Unitized bond construction with very hard density for shape retention under load
• 35,100 RPM maximum speed rating for use with high-speed die grinders
• 0.25-inch shank diameter fits standard collets on most die grinders and rotary tools

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.25-inch shank. Verify that the tool RPM rating meets or exceeds the 35,100 RPM maximum before mounting.

Installation Notes

Mounting and use should be performed by a machinist or trained technician familiar with abrasive tooling safety. Always confirm the spindle speed of the grinder does not exceed the 35,100 RPM maximum rating of this mounted point before operation. Inspect the abrasive for cracks or chips before each use and never use a damaged point. Secure the shank fully in the collet and tighten to the tool manufacturer specification before running.
