Sandvik Coromant notes that flexible drilling is key to making machining processes more economical. One enabler is the Corodrill Dura 462 drill...

In January, the World Economic Forum reported that selected production sites in its Global Lighthouse Network are achieving productivity gains of 70 percent. And this was achieved with reduced energy costs and shorter time to market (by 40 percent in each case). But how can such efficiency be achieved without driving up costs and with such a wide variety of materials? Sandvik Coromant has the answer! It is a new, flexible drilling tool for multi-material applications.

Drilling is an old process, but today it is no trivial matter

Drilling is a fundamental but technically demanding manufacturing process, as the Swedes emphasise. One of the biggest challenges is the wide variety of materials that need to be machined. Their properties range from tough, hardened steels to light but ductile metals. And every material has its own special characteristics. Hardened steels can cause excessive tool wear, while softer metals are more easily deformed. Heat generation and tool wear are the critical factors here. High cutting speeds, long machining cycles and demanding material combinations generate excessive heat. This not only accelerates tool wear, but also impairs machining accuracy. This can lead to surface defects and dimensional deviations, for example. According to Sandvik Coromant, effective heat management — both in tool design and machining strategies — is therefore crucial when it comes to maximising the service life of cutting tools and ensuring the quality of components.

The next hurdle for efficient drilling

Another problem is chip removal, as the report goes on to say, because in deep-hole drilling or applications with high feed rates, inadequate chip removal can lead to clogging, increased heat generation and even tool failure. For these reasons, drill flutes must be designed to allow chips to be removed easily and evenly in order to ensure stable machining conditions during drilling. The exact positioning and straightness of holes are also crucial in the precision manufacturing of high-quality components for the aerospace and automotive industries. Even slight deviations can impair the function of the end product and lead to expensive rework or even scrap. Robust tool geometries and optimised machining parameters are therefore required to ensure the necessary stability. This is where the Corodrill Dura 462 can help.

That's why the Corodrill Dura 462 is a multi-talented tool

The Sandvik Coromats Corodrill Dura 462 has been specially developed for high drilling performance in various materials. With its fine-grained carbide substrate, it offers high wear resistance and therefore reliability. The controlled microstructure ensures consistent results, even when drilling demanding materials (hard metals or ductile alloys). This makes this drill a valuable tool for machinists who expect consistent precision and stability regardless of the material composition of their components. The geometry of the Corodrill Dura 462 is naturally designed for a wide range of materials. The special tip design significantly reduces cutting forces and improves positioning accuracy, especially in applications with tight tolerances. The drill's clearance angle increases tip strength, while the single-edged design reduces heat build-up, according to the Swedish manufacturer. This feature increases stability and optimises overall performance.

Two practical drilling examples are convincing

The drill becomes even more powerful in combination with the patented PVD coating called Zertivo 2.0. In combination with the fine-grained carbide substrate, it ensures even higher wear resistance and thus enables high-speed drilling with consistently high process stability. Practical tests prove the competitive advantages of the tool: one user was able to increase productivity by 110 percent and extend tool life by 36 percent with the Corodrill Dura 462. In another case, a productivity increase of 85 percent was achieved — with more than double the tool life compared to a competitor's drill.
