|---|---|
The High-Performance Indexable Gun Drills are advanced cutting tools designed to deliver unmatched productivity and precision in deep hole drilling applications. Featuring replaceable carbide inserts and a modular design, these drills enable efficient hole formation in diameters 12mm-100mm and depths up to 3 meters, with quick insert changes minimizing downtime in high-volume manufacturing.
Modular Insert System:
Indexable carbide inserts (K10/K20 grades) with multiple cutting edges, allowing rapid rotation/change to extend tool life by 300% compared to solid carbide drills.
Self-locking wedge mechanism ensures insert positioning accuracy within ±0.01mm, maintaining hole straightness and diameter consistency.
Optimized Cutting Geometry:
135° split point angle reduces thrust force by 25%, while variable helix flutes (30°-45°) improve chip evacuation in sticky materials like stainless steel and aluminum.
Coolant-through design with 45° angled nozzles direct high-pressure fluid (150 bar) to the cutting edge, enhancing heat dissipation and reducing insert wear.
Rigid Tool Body:
High-strength alloy steel shank (1,200 MPa tensile strength) with anti-vibration ribs, ensuring stability during deep drilling (depth-to-diameter ratio 100:1).
Ideal for industries requiring high-efficiency deep hole drilling:
Oil & Gas Pipelines: Drilling large-diameter holes (50mm-100mm) in steel pipes for subsea connections, compliant with API 5L and ASME B31.3 standards.
Heavy Equipment Manufacturing: Machining deep holes in excavator arms and crane booms, supporting fast cycle times in high-volume production lines.
Power Generation: Drilling cooling holes in steam turbine rotors, ensuring dimensional accuracy (±0.02mm) for tight-fit bearing installations.
Cost-Effective Productivity: 50% lower cost per hole than solid carbide drills through insert indexing, with quick-change design reducing tool change time to 30 seconds.
Application Support: Free drilling parameter optimization by our engineers, helping customers achieve maximum feed rates (0.3mm/rev) and spindle speeds (8,000 RPM).
Global Aftersales: 24-hour insert replacement service and stock availability of over 500 insert types, minimizing downtime for international manufacturing plants.
