Standard Abrasives 7000121921 Mounted Point W185 Fine

Product Description

The STANDARD ABRASIVES 7000121921 is a cylinder-shaped mounted point designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built with aluminum oxide abrasive in a unitized bond, this point delivers consistent fine-grade cutting action throughout its service life. The hard density construction maintains shape under load, making it well-suited for controlled stock removal in tight geometries. It fits a 1/8 inch shank and measures 1/2 inch in head thickness, with a rated maximum speed of 34,500 RPM. Machinists, tool and die technicians, and metalworking professionals typically reach for this type of mounted point when working in die grinders or rotary tools.

This mounted point is appropriate for use in both production and maintenance environments where fine surface finishing, edge cleanup, or cavity blending is required. The W185 cylinder shape provides flat-face contact, which suits work on flat surfaces, shoulders, and recessed areas. Its compact shank diameter makes it compatible with standard die grinders and rotary tools used in fabrication, weld finishing, and mold work. The fine grade is suited for finishing passes rather than aggressive material removal.

Key Features

• Aluminum oxide abrasive construction for consistent fine-grade performance on metal
• Unitized bond holds abrasive grain evenly, supporting shape retention through the life of the point
• Hard density rating provides controlled cut with minimal deflection under load
• W185 cylinder point shape delivers flat-face contact for blending and finishing on flat or shouldered surfaces
• Rated to 34,500 RPM for compatibility with standard die grinders and rotary tools
• 1/8 inch shank diameter fits widely used collets and chucks

Compatibility

Designed for use in die grinders and rotary tools accepting a 1/8 inch shank collet. Suitable for fine grinding and finishing applications on ferrous and non-ferrous metals in production and maintenance settings.

Installation Notes

Mounted points must be installed in a collet or chuck rated for the shank diameter — verify collet size before mounting. Always confirm the tool spindle speed does not exceed the 34,500 RPM maximum rating of this point before operation. Inspect the point for cracks or damage before each use, and never use a damaged abrasive accessory. Eye protection and appropriate PPE are required per ANSI B7.1 safety standards for abrasive product use.
