Drills for High-Heat Applications

The Elect S drills by Precision Dormer are developed specifically for the machining of materials known collectively as Heat Resistant Super Alloys (HRSA). Including high-temperature resistant alloys such as titanium, Inconel and Waspalloy, these materials can be difficult to machine.

Including high-temperature resistant alloys such as titanium, Inconel and Waspalloy, these materials can be difficult to machine. First, they generate high cutting forces during machining, leading to high pressure and heat, which in turn, tends to result in work hardening. Second, because the materials are able to withstand high temperatures, 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, several features of the Elect S drills combine to lower the occurrence of work hardening. These include a body back taper that promotes a free, continuous cutting action as well as high quality, accurate holes. A self-centering 140-degree point angle, cylindrical margin and positive cutting edge geometry also work to minimize frictional cutting forces, leading to consistent tool performance and minimal work hardening.
