Norton 614636-20242 Cotton Fiber Mounted Point B52 A120

Product Description

The NORTON 614636-20242 is a cotton fiber mounted point designed for precision grinding and surface finishing in metalworking and fabrication applications. Built to B52 shape specifications with an A120 grit aluminum oxide abrasive and HBF3 bond designation, this mounted point delivers consistent stock removal and surface refinement on ferrous and non-ferrous materials. The 1/8-inch shank allows use with standard die grinders and rotary tools. At 0.01 pounds, it is a lightweight single-use consumable suited to detail work in confined areas. Machinists, tool-and-die workers, and fabricators typically select this point for internal grinding, deburring, and contour finishing tasks.

Cotton fiber construction in this mounted point provides a semi-flexible cutting action, making it well suited for blending, light stock removal, and finishing passes on curved or irregular surfaces. The B52 profile shape is commonly used for internal bore work, slot grinding, and reaching recessed geometry that standard wheel profiles cannot access. This point is sold individually and is appropriate for professional shop use, maintenance grinding, and prototype finishing operations.

Key Features

• B52 shape profile for internal and contour grinding applications
• A120 grit aluminum oxide abrasive for fine stock removal and surface finishing
• HBF3 bond designation for consistent abrasive retention and cutting action
• Cotton fiber construction provides semi-flexible grinding action on irregular surfaces
• 1/8-inch shank compatible with standard die grinders and rotary tools
• Lightweight at 0.01 pounds — minimal tool loading during extended use

Compatibility

Designed for use with die grinders, rotary tools, and mounted point spindles accepting a 1/8-inch shank. Verify maximum RPM rating of the host tool against the mounted point specifications before use.

Installation Notes

Mounted points are installed and removed by a qualified machinist or fabricator using a collet-style chuck on a die grinder or rotary tool. Always power down and disconnect the tool from its power source before changing mounted points. Inspect the point for cracks or damage before each use and never operate above the rated maximum RPM. Eye protection and appropriate PPE are required during all grinding operations per ANSI B11 and applicable shop safety standards.
