As manufacturers strive to improve process stability, increase productivity and support unattended production, tooling is playing an increasingly important role. According to Sandvik Coromant, a recent collaboration with direct-drive system manufacturer Hägglunds demonstrates how the right drilling solution can transform machining performance without replacing existing equipment.
Hägglunds, a Bosch Rexroth brand, was experiencing inconsistent results when drilling bearing steel cam rings. The existing drill lacked the durability and reliability required for predictable hole quality, preventing operators from running machines unattended and limiting overall productivity.
Working closely with Hägglunds, Sandvik Coromant identified the need for a more stable, wear-resistant drilling solution. The company recommended its second-generation CoroDrill DE10 exchangeable-tip drill, which features a patented pre-tension clamping interface that delivers high stability, accurate centring and consistent hole quality, even in demanding applications.
During production trials, the CoroDrill DE10 demonstrated repeatable performance over thousands of holes while supporting higher cutting data and extended tool life. The versatile -M5 tip geometry also eliminates the need for a pilot drill and enables rapid tip changes without spare parts, helping to simplify operations.
The improvements allowed Hägglunds to increase productivity by 18%, while doubling cutting time per drill tip from 40 to 80 minutes. Greater process reliability also enabled operators to leave machines running unattended, freeing them to focus on other tasks and supporting more efficient production.
Sandvik Coromant says the project highlights the value of its broader manufacturing wellness approach, which combines advanced tooling with engineering expertise, process optimisation and customer collaboration. Rather than relying on costly machine upgrades, manufacturers can improve output, extend tool life and strengthen operational resilience by optimising existing machining processes. The result is greater process stability today and a stronger foundation for future automation and lights-out manufacturing.
