Grier Abrasives W154-N2-17204 Mounted Point Fine

Product Description

The GRIER ABRASIVES W154-N2-17204 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing on metal and other hard materials. Built with aluminum oxide abrasive grain and a unitized bond type, this mounted point delivers consistent material removal at medium density and fine grade. It fits a 1/8-inch shank and spins up to 70,500 RPM, making it suited for high-speed rotary tools, die grinders, and pneumatic pencil grinders used in production and maintenance environments. Machinists, tool-and-die workers, and maintenance technicians are the primary installers of this type of abrasive tooling.

This mounted point is used in applications requiring controlled stock removal or surface conditioning in confined areas where larger abrasive wheels cannot reach. The W154 cylinder shape provides a flat working face and cylindrical side contact, which is effective for internal bore finishing, slot grinding, and edge blending. The fine grade and green aluminum oxide construction make it appropriate for finishing passes on ferrous metals and cast iron components in both shop and field maintenance settings.

Key Features

• Cylinder point shape (W154) with flat face and side grinding capability
• Aluminum oxide abrasive grain for use on ferrous metals and cast iron
• Fine grade abrasive for finishing and light material removal
• Unitized bond construction at medium density for consistent wear
• Maximum rated speed of 70,500 RPM for use with high-speed die grinders
• 1/8-inch shank diameter with 1.5-inch shank length for standard collet fitment

Compatibility

Designed for use with die grinders, rotary tools, and pneumatic pencil grinders equipped with a 1/8-inch collet. Fits standard 1/8-inch shank tooling setups common in metal fabrication and maintenance applications.

Installation Notes

Mounted points are installed by machinists or maintenance technicians using a matching collet in a die grinder or rotary tool. Always confirm the tool's rated RPM meets or exceeds the 70,500 RPM maximum before mounting. Ensure the shank is fully seated in the collet and the collet nut is properly tightened before operation. Wear appropriate eye and face protection per ANSI B7.1 guidelines when operating abrasive tooling.
