Grier Abrasives W154-S6-17240 Mounted Point Fine Silicon Carbide

Product Description

The GRIER ABRASIVES W154-S6-17240 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing on hard materials. Built from silicon carbide with a unitized bond and a fine grade, it delivers consistent cut and smooth surface contact. The point measures 0.5 inches in thickness with a 1/8-inch shank diameter and a 1.5-inch shank length. With a maximum RPM rating of 70,500, this mounted point is suited for high-speed rotary tools and die grinders used in metal fabrication, mold work, and tooling applications. It is installed and operated by machinists, tool and die makers, and skilled trade professionals.

This mounted point fits standard 1/8-inch collet die grinders and rotary tool attachments. The W154 cylinder profile makes it well suited for internal diameter grinding, slot finishing, and contour work on hard metals, carbide, ceramics, and cast iron. The fine grade and medium density are appropriate for finishing passes and light stock removal where surface quality is a priority. Its compact size allows access to tight cavities and restricted work areas common in mold and die applications.

Key Features

• Silicon carbide abrasive material for effective grinding on hard and brittle materials
• W154 cylinder point shape for internal grinding and slot finishing
• Fine grade with medium density for smooth finishing passes
• Maximum rated speed of 70,500 RPM for high-speed rotary tool use
• 1/8-inch shank diameter fits standard die grinder collets
• Unitized bond construction for consistent abrasive exposure throughout use

Compatibility

Designed for use with die grinders and rotary tools fitted with a 1/8-inch collet. Suitable for grinding applications on hard metals, ceramics, and carbide surfaces where silicon carbide abrasive performance is required.

Installation Notes

This mounted point is installed by securing the 1/8-inch shank into the collet of a compatible die grinder or rotary tool. Always confirm the tool spindle speed does not exceed the 70,500 RPM maximum rating before operation. Ensure the collet is tightened securely and inspect the point for cracks or damage before each use. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
