HEULE (Cincinnati, OH) introduces DEFA tooling which provides a wide range of adjustment for chamfering operations in difficult-to-machine materials like Inconel, Titanium, 4140 Steel, and others with large burr formation. Robust construction and an advanced dual-cutting system with exchangeable carbide blades enable front and back or back-only chamfering of bores from 4 mm to 36.2 mm (0.157” to 1.425”), to handle a wide range of machining requirements. Its unique blade geometry incorporates a sliding surface that enables chamfer cutting without compromising the integrity of the bore surface or interfering cross holes, ensuing surface quality.
This unique dual-cutting tool provides machinists with precise control over chamfer sizes across a range of on-tool adjustments, yielding flexibility to accommodate diverse bore dimensions and project specifications. Featuring an exchangeable carbide blade set with a material-specific coating, the DEFA tool delivers consistent and reliable performance in challenging machining environments.
A key advantage of the DEFA tool design lies in its ability to safeguard the integrity of the hole. The DEFA tool can produce chamfers up to .050” a side, to produce a large chamfer before the thread or tap, creating a lead for the tap, and ensuring that the chamfer is larger than the OD (Outer diameter) of the thread during the chamfering process. This is achieved through the sliding surface geometry of the DEFA blades, which effectively mitigates the risk of damage, ensuring consistent surface quality.
