The Elect S drill range is designed for heat-resistant superalloy (HRSA) materials, including titanium, Inconel and Waspalloy. According to the company, these materials can be difficult to machine because they generate high cutting forces, which lead to high pressure and heat. Also, the heat generated during drilling is retained within the workpiece and transferred to the tool, resulting in premature drill failure.
In addition to internal coolant holes, other features combine to lower the occurrence of work hardening, such as a body back taper that promotes free, continuous cutting as well as high-quality, accurate holes. A self-centering, 140-degree point angle, cylindrical margin and positive cutting edge geometry also minimize frictional cutting forces.
A Smooth-Flow coating acts as a thermal barrier to protect the substrate from extreme heat generated at the cutting edge. It has a low coefficient of friction for smooth and efficient chip evacuation and extended tool life.
Available in two lengths to support drilling to 3 × D (R507) and 5 × D (R503), the drills are suited for production of high-value components as well as high-precision machining required in aerospace, subcontracting, nuclear and oil and gas industries.
