Cutter combines core-hole drilling, chamfering, and threading in one tool

Walter Tools has introduced its Thrill∙tec TC645 Supreme thread milling cutter, which combines the machining steps of core-hole drilling, chamfering, and threading in a single tool.

The tool creates the core hole and threads using helical interpolation. The left-hand cutting tool can also be used for chamfering, which should take place before thread milling at the thread entry. The tool’s face, or front milling geometry, enables core-hole drilling, chamfering, milling, and threading.

The thread mill is made of the high-performance coated WB10TJ grade to enable universal machining of steel, stainless steel, cast iron, nonferrous metal, and super alloys and titanium alloys.

Other features include a modified cutting geometry to avoid chipping, and an internal coolant duct for emulsion, makes it possible to maximize tool life when machining workpiece materials as hard as 48 HRC.

These features and a 20-degree helix mean it can create blind-hole and through-hole threads at projection lengths of 2- and 2.5-times deep, according to the company.

It is offered in dimensions of M4 to M12, UNC 8 to UNC ½ and G1/16 to G¼, with plans for additional versions coming soon. The shank is in accordance with the DIN 6535 HA standard.
