Heule Cofa Deburring Tool for Elliptical, Contoured Surfaces

Heule Precision Tools’ Cofa tool is a universal deburring tool specifically designed for front and back deburring on even and uneven bore edges using CNC machinery. The tool is well suited for a range of cross-hole deburring applications including sloped bores. It also creates even and consistent edge breaks.

Controlled by a simple spring, the carbide cutting blade follows the contour of the hole’s surface to remove all burrs while creating an even tapered corner break. The company says the blade does not cut as it passes through the bore and will not damage the hole’s surface. The edge break begins only at the point where the blade makes contact with the material and then tapers the hole’s edge. This enables faster feed rates because the tool slows itself down as it enters the through hole.

The tool can handle ID and OD deburring without the need to stop or reverse the spindle, and is suitable for a variety of machine materials. A coated carbide blades ensures long tool life and faster feeds and speeds for increased performance.

Typical applications include forks, yokes, common rails, castings, tubes with cross bores and other work pieces with cross bores in main bores.

Cofa is available in both First Generation Cofa and New Generation Cofa-C for larger edge breaks. It is also available in smaller sizes for microdeburring applications.
