Harvey Tool 891145-C3 Flat Abrasive Bur 3/16 Inch

Product Description

The HARVEY TOOL 891145-C3 is a flat abrasive bur designed for material removal, deburring, and surface finishing in metalworking and machining applications. The bur features a 3/16 inch (0.1875 inch decimal) shank diameter and a 90-degree included angle on the cutter head, making it suited for working in angled recesses, chamfered edges, and flat-bottom profiles. At 0.04 pounds, it is a lightweight, single-piece tool intended for use in rotary die grinders, flexible shaft machines, or similar high-speed rotary equipment. Machinists and tool-and-die professionals are the primary users of this type of bur.

This flat abrasive bur is used in both shop and field applications where precision surface work is required on metal, hardened steel, or similar materials. Typical scenarios include weld blending, edge preparation, and cavity finishing on molds, dies, and machined components. The 3/16 inch shank fits standard collets found on most die grinders and rotary tools commonly used in machine shops and fabrication environments.
