Value Collection -22686-1 Abrasive Bur Tree Radius SF-42

Product Description

The VALUE COLLECTION -22686-1 is a solid carbide abrasive bur ground to the SF-42 industry specification with a tree-with-radius-end head geometry. It features a 0.25 inch cutting diameter and a 0.5 inch length of cut, mounted on a 0.125 inch shank. The solid carbide construction delivers hardness and wear resistance suited to deburring, porting, and shaping operations on ferrous and non-ferrous metals, plastics, and composites. The uncoated head allows direct inspection of the cutting surface and is compatible with standard die grinders and rotary tools used in machining and fabrication environments.

This bur is used in metalworking, tool-and-die, welding, and general fabrication shops where controlled material removal in curved or contoured areas is required. The tree-with-radius-end profile allows access into concave surfaces, radius pockets, and weld seams. It is sized for 0.125 inch collet systems, which are common on air-powered die grinders and electric rotary tools used by machinists, maintenance technicians, and fabricators.

Key Features

• SF-42 industry specification — ensures standardized geometry and interchangeability
• Tree with radius end profile — accesses concave surfaces, radius pockets, and weld zones
• Solid carbide head — resists wear and maintains edge geometry longer than high-speed steel alternatives
• Uncoated finish — no coating to chip or flake during high-speed grinding operations
• 0.125 inch shank — fits standard 1/8 inch collets on die grinders and rotary tools

Compatibility

Designed as an OEM-style replacement or standard-stock carbide bur for use in any die grinder or rotary tool accepting a 0.125 inch shank collet.

Installation Notes

Installation is performed by machinists or fabricators using a die grinder or compatible rotary tool with a 0.125 inch collet. Secure the shank fully into the collet and tighten to manufacturer-specified collet torque before operation. Always wear appropriate eye protection and secure the workpiece before engaging the bur. Inspect the carbide head for cracks or chips before each use and replace if damage is observed.
