Key Functions & Benefits

Deep-Hole Precision: Easily achieves up to 6D drilling depths while maintaining exceptional hole straightness and surface finish.
Superior Thermal Control: Internal cooling channels force coolant directly into the cutting zone to prevent thermal deformation and rapid tool wear.
Enhanced Stability & Safety: The dual front-locking and side-locking architecture guarantees that the drill tip remains securely anchored during high-torque, high-speed rotations.
Cost-Efficient Indexable Design: Eliminates the need for regrinding. Changing worn inserts is fast and simple, drastically reducing machine downtime.

Target Applications

Heavy Machinery & Automotive Manufacturing: Ideal for drilling engine blocks, transmission shafts, and structural frames.
Mold & Die Industry: Perfect for machining deep ejector pin holes, cooling lines, and core cavities.
Energy & Aerospace: Extensively used in processing large flanges, heat exchangers, and turbine components.
Compatible Materials: Highly effective across a wide range of materials, including carbon steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
