Inovatools’ Speedmax twist drill is designed for drilling in stainless steel, titanium and alloy steels at higher feed rates and with longer service life. The Speedmax HA, HB and HE shanks with h6 tolerance combine geometry, chip control and high-performance coating properties to meet the demands of these metals, the company says. The drill is made of tough, micro-grain carbide and has chamfered cutting edges. This chamfer preparation eliminates any tiny nicks and anomalies at the micron scale, which makes the cutting edges more stable and therefore more resistant to premature wear due to edge breakouts and micro cracks, the company says. The tool also features a high-performance coating that also has a positive impact on wear behavior and service life.

The lifting frontal polished section and the six-surface point thinning also are said to increase the tool’s performance, providing not only self-centering capabilities but also optimal chip shape generation. A special groovechip space with extremely flat surfaces helps to remove chips from the contact zone quickly. This controlled-speed chip removal is aided by the drill’s precise internal cooling.
