Grier Abrasives W185-N3-17228 Mounted Point Medium

Product Description

The GRIER ABRASIVES W185-N3-17228 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing in metalworking and fabrication applications. Built with aluminum oxide abrasive grain and a unitized bond type, this mounted point delivers consistent material removal at a medium grade. The shank diameter measures 1/8 inch with a shank length of 1.5 inches, and the grinding head is 0.5 inches thick. Rated to a maximum of 34,500 RPM, it is suited for use with standard die grinders and rotary tools. The green color coding identifies the medium density and hardness classification.

This mounted point is used in metalworking shops, maintenance facilities, and light manufacturing environments where controlled grinding and finishing of metal surfaces, ports, welds, or internal cavities is required. The W185 cylinder shape is a common configuration for work inside bores, slots, and recessed areas. It is typically installed by machinists, tool-and-die workers, metal fabricators, and maintenance technicians using pneumatic or electric die grinders.

Key Features

• Cylinder point shape (W185) for grinding bores, slots, and recessed surfaces
• Aluminum oxide abrasive grain for consistent material removal on ferrous metals
• Unitized bond type for controlled cut rate and durability
• Medium grade and medium density for balanced stock removal and surface finish
• Rated to 34,500 RPM for use with standard die grinders
• 1/8 inch shank diameter fits common collet sizes on rotary and die grinder tooling

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch collet or chuck. Suitable for grinding aluminum oxide-compatible applications on ferrous and non-ferrous metal surfaces.

Installation Notes

Mounted points must be installed by trained personnel using a properly sized collet that matches the 1/8 inch shank diameter. Always confirm the tool's rated RPM meets or exceeds the 34,500 RPM rating before mounting. Inspect the abrasive for cracks or damage before each use and never exceed the maximum RPM marked on the point. Use appropriate personal protective equipment including eye protection and gloves when operating grinding equipment.
