Value Collection -22690-3 Abrasive Bur Taper Solid Carbide

Product Description

The VALUE COLLECTION -22690-3 is a solid carbide abrasive bur with a taper and radius end head geometry, designed for material removal, deburring, and shaping operations in metalworking and fabrication applications. The 3/8-inch cutting diameter and 1-1/16-inch length of cut make it well suited for contouring work in tight areas. The 1/4-inch shank fits standard die grinders and rotary tools used by machinists and maintenance technicians. Industry specification SL-3 governs the geometry of this bur. The uncoated solid carbide head delivers consistent cutting performance across ferrous and non-ferrous metals as well as hard plastics and composites.

This abrasive bur is used in metalworking shops, manufacturing facilities, and maintenance environments where precision material removal is required. The taper with radius end profile is suited for blending radii, cleaning weld beads, and shaping internal contours. It is installed in die grinders, flexible shaft machines, or similar rotary handpieces operating at appropriate speeds for carbide burs. Machinists, tool and die workers, and maintenance technicians are the primary users of this style of bur.

Key Features

• Solid carbide head construction for long service life in hard materials
• Taper with radius end geometry for contouring and blending operations
• 3/8-inch cutting diameter suitable for moderate material removal in confined spaces
• 1-1/16-inch length of cut provides extended reach for internal work
• 1/4-inch shank diameter fits most standard die grinders and rotary handpieces
• Uncoated head for broad material compatibility without coating-related speed restrictions

Compatibility

Designed as an SL-3 specification abrasive bur for use in die grinders and rotary handpieces that accept a 1/4-inch shank. Confirm your tool collet size before installation.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder or similar rotary tool with a compatible 1/4-inch collet. Secure the shank fully in the collet and tighten according to the tool manufacturer's specifications before operating. Always wear appropriate eye protection and secure the workpiece before applying the bur. Do not exceed the maximum RPM rating of the bur or the tool to prevent breakage.
