• Improved customer productivity through enhanced machining efficiency
TPDK
KORLOY introduces the Top Solid Indexable Drill TPDK, delivering unwavering stability even in highload machining environments.
The TPDK offers a proprietary DTF™ (Dura Taper Fit) clamping system based on a taper-shaped post design, providing exceptional rigidity and durability for stable machining performance under demanding conditions such as stacked plate processing. Its optimized point angle and flute cutting edge design enable smooth chip formation and efficient chip evacuation, enhancing overall machining efficiency.
Featuring a headless bolt design, the DTF™ clamping method improves clamping convenience compared to conventional screws and enables rapid insert replacement, significantly reducing setup time. Additionally, periodic replacement of the headless bolt helps to extend holder's tool life.
The TPDK holder incorporates a variable web thickness structure that reinforces clamping rigidity and improves chip management performance. Spiral oil holes and treated flute surfaces maximize chip evacuation stability. Furthermore, a dedicated grade utilizing an ultra-fine substrate and lubricative thin-film coating suppresses cutting edge damage and enhances wear resistance, ensuring longer tool life and consistently stable machining quality.
TPDK improves customer productivity and reduces manufacturing costs through impoved tool life and machining efficiency.
