Value Collection -22690-4 Abrasive Bur Taper 1/2 in Carbide

Product Description

The VALUE COLLECTION -22690-4 is a solid carbide abrasive bur with a taper with radius end head shape, conforming to industry specification SL-4. Designed for material removal, deburring, and surface finishing in metalworking and fabrication applications, this bur features a 1/2-inch cutting diameter and a 1-1/8-inch length of cut. The 1/4-inch shank fits standard die grinders and rotary tools commonly used in machine shops, maintenance facilities, and production environments. The uncoated solid carbide construction delivers consistent cutting performance on ferrous and non-ferrous metals.

This abrasive bur is suited for use in metalworking, tool and die, welding, and general industrial maintenance applications. The taper with radius end geometry is effective for contouring, chamfering, and blending in confined areas or along curved surfaces. Machinists, tool grinders, and fabricators typically use this style of bur in die grinders or flexible shaft machines where precision material removal is required.

Compatibility

Designed as an SL-4 specification abrasive bur for use with die grinders and rotary tools accepting a 1/4-inch shank collet.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder or flexible shaft machine with a 1/4-inch collet. Ensure the tool is powered off and unplugged before inserting or removing the bur. Secure the shank fully in the collet per the tool manufacturer's torque guidelines and verify the bur runs true before engaging the workpiece. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary cutting tools.
