Heule Tool Corporation’s COFA C Series is an elliptical deburring tool with exchangeable blade options. This tool system removes burrs on the front and back of a drilled through-hole on even and uneven surfaces in a single cycle. The new generation of the COFA series is a product line expansion that offers more options for each tool body. The tools offer larger edge breaks and will now have the availability to house different size blade options for each tool body. In COFA C6 to C20, the swivel movement is guided by a blade holder. This way, the cutting edge follows the uneven bore edge. The more the tool enters into the bore, the more the blade swings into the tool body. The result is a radially shaped consistent deburring of the bore edge. This allows for faster feed rates since the tool slows itself down as it enters the through hole.

The simple concept of the tool has no adjusting screws or presetting requirements—only a choice of common tool sizes and spring strengths for various materials and hole sizes.
