Exceptional Deep-Hole Penetration: The rigid 6D structure easily handles deep boring tasks while maintaining tight dimensional tolerances and preventing drill deflection.
Rapid Tool Changes: The front-locking mechanism and side-locking drill tip allow operators to swap inserts quickly without removing the entire tool holder from the spindle.
Advanced Thermal Control: Built-in internal cooling channels deliver high-pressure coolant directly to the cutting edge, reducing heat friction and drastically extending tool life.
Superior Chip Evacuation: Continuous coolant flow combined with optimized flute geometry forces chips out of deep cavities instantly, preventing chip clogging and workpiece scratching.
Cost-Efficient Machining: Indexable insert design eliminates the need for expensive regrinding—simply replace the worn tip to restore brand-new drilling performance.
This tool is ideally suited for heavy industrial environments requiring high-speed, high-accuracy deep holes:
Automotive Industry: Heavy-duty engine blocks, crankshafts, and transmission components.
Aerospace & Defense: Structural frames, landing gear components, and turbine parts.
Mold & Die Making: Deep cooling lines and ejector pin holes in large injection molds.
Oil & Gas / Energy: Valve bodies, flanges, tubesheets, and heavy machinery components.
General Machinery: Production of heavy shafts, cylinders, and thick-walled steel pipes.
Excellent for high-speed machining across diverse material groups:
Carbon Steels & Alloy Steels
Stainless Steels (Austenitic & Martensitic)
Cast Iron (Ductile and Gray Iron)
High-Temperature Alloys
