IMPROVED TOOL LIFE

In this application, an 8×D tool overhang was required to avoid interference, while the actual hole depth was less than 3×D. The existing competitor's 8×D drill suffered from unstable machining due to the long overhang condition, resulting in cutting edge chipping and limited tool life. To address this issue, the DrillMeister modular shank was selected to provide a highly rigid tooling setup capable of maintaining stability even under extended overhang conditions. As a result, excellent machining stability was achieved, edge chipping was effectively suppressed, and tool life was improved approximately threefold, increasing from 324 holes to 972 holes.
