DRILLSTAR CARBIDE TOOLS ARE WORKING IN MANY PLACES AROUND THE WORLD
Carbide BTA Deep Hole Drills are premium cutting tools designed to excel in the most demanding deep-hole drilling applications, leveraging the hardness and wear resistance of tungsten carbide to deliver precision, durability, and efficiency. Compatible with BTA (Boring and Trepanning Association) drilling systems, these drills feature a single-tube design where coolant flows through the drill body to evacuate chips through the annular space between the tool and workpiece, ensuring stable operation at depths up to 10 meters.
Engineered for machining tough materials like hardened steel (up to 55 HRC), titanium alloys, and nickel-based superalloys, these drills combine a carbide cutting head with a high-strength steel shank for optimal rigidity. Their precision-ground geometries and advanced coatings minimize friction and heat generation, enabling consistent hole quality (roundness ≤0.03mm, surface roughness Ra ≤1.2μm) even in deep, high-aspect-ratio drilling. Whether used in aerospace, energy, or heavy machinery industries, Carbide BTA Deep Hole Drills set a new benchmark for productivity in challenging deep-hole operations.
1. Carbide Cutting Edge: Solid carbide or carbide-tipped inserts (grade K10-K30) provide superior hardness (1,300–1,800 HV) and wear resistance compared to high-speed steel, reducing tool changes and downtime.
2. Optimized Chip Flute Design: Helical or straight flutes with variable pitch enhance chip breaking and evacuation, preventing blockages in deep holes. Chipbreaker grooves further control chip size for easy removal.
3. Advanced Coating Technology: PVD-applied TiAlN or AlCrN coatings (thickness 3–5μm) reduce friction by 30%, lower cutting temperatures by 150°C, and extend tool life by 40% in abrasive materials.
4. Precision Balancing: Shanks are dynamically balanced to G2.5 standards, minimizing vibration at high spindle speeds (up to 5,000 RPM) and ensuring stable cutting performance.
5. Customizable Geometry: Available with different point angles (118°–140°), relief angles, and margin widths to suit specific workpiece materials and drilling depths.
Aerospace Components: Drilling deep holes in titanium alloy wing spars and nickel-based superalloy engine casings, where tool stability and surface finish are critical for structural integrity.
Energy Sector Equipment: Machining deep holes in oil country tubular goods (OCTG), nuclear reactor pressure vessels, and wind turbine hub shafts, ensuring dimensional accuracy in thick-walled components.
Heavy Machinery: Production of hydraulic cylinders, axle housings, and mining equipment parts, enabling efficient drilling of large-diameter holes (20–200mm) in high-strength steel.
Automotive Dies & Molds: Precision deep holes in die-casting molds and stamping dies, requiring tight tolerances for cooling channels and ejector pin bores.
Q: How do I choose the right carbide grade for my material?
A: Use K10-K20 grades for non-ferrous metals and low-carbon steels, K20-K30 for high-strength steels and superalloys. Contact our technical team for material-specific recommendations.
Q: Can these drills be resharpened after wear?
A: Yes, solid carbide drills can be reconditioned 2–3 times via precision grinding, restoring cutting edges to near-original performance. Reconditioning turnaround time is typically 5–7 days.
Q: What coolant pressure is required for optimal chip evacuation?
A: Minimum 80 bar for holes <50mm diameter; 120–150 bar for deeper or larger-diameter holes. Use clean, high-viscosity synthetic coolant (40–60 cSt at 40°C) for best results.
Q: Do you offer custom lengths for special applications?
A: Yes, drills can be manufactured up to 12 meters in length with custom shank configurations (e.g., Morse taper, cylindrical with keyway) to fit specific machine tool interfaces.
