Standard Abrasives 7010310349 Mounted Point B121 Fine

Product Description

The STANDARD ABRASIVES 7010310349 is a ball-shaped mounted point designed for precision grinding, deburring, and surface blending on metal and similar hard materials. Classified as shape B121, this mounted point features a fine-grade aluminum oxide abrasive bonded in a unitized construction for consistent stock removal and a uniform finish. The hard density bond holds the abrasive firmly during high-speed operation, with a maximum rated speed of 45,300 RPM. The 1/8-inch shank fits standard die grinder collets, and the 1/2-inch head thickness provides adequate contact area for contour work and internal cavity finishing.

This mounted point is suited for tool and die work, weld blending, port work, and general metalworking applications in fabrication shops, maintenance environments, and production grinding operations. The fine grade makes it appropriate for finishing passes rather than aggressive material removal. It is typically used by machinists, tool and die makers, and maintenance technicians working on ferrous metals and hard alloys where controlled surface finish is required. Sold individually per package with a minimum order quantity of 5 units.

Key Features

• Ball shape (B121) suited for contour grinding, deburring internal radii, and cavity blending
• Fine-grade aluminum oxide abrasive for finish-pass surface refinement
• Unitized bond construction with hard density rating for consistent performance under load
• Maximum operating speed of 45,300 RPM compatible with standard die grinders
• 1/8-inch shank diameter fits common die grinder and rotary tool collets
• Compact 1/2-inch head thickness for access to tight contours and recessed areas

Compatibility

Designed as an OEM-style replacement mounted point for die grinders and rotary tools accepting a 1/8-inch shank collet. Verify maximum RPM rating of the host tool does not exceed 45,300 RPM before use.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder or rotary tool with a compatible 1/8-inch collet. Always confirm the tool's rated RPM does not exceed the 45,300 RPM maximum before mounting. Secure the shank fully into the collet and tighten per the tool manufacturer's specification before operation. Inspect the mounted point for cracks or damage before each use and do not use a damaged abrasive.
