DRILLSTAR CARBIDE TOOLS ARE WORKING IN MANY PLACES AROUND THE WORLD
The Solid Carbide Gun Drill with a Single Flute Tool is a cutting-edge solution for precision deep hole drilling in high-strength materials where dimensional accuracy and surface finish are non-negotiable. Crafted from premium micrograin solid carbide (WC-Co), this drill leverages its monolithic design and single flute geometry to achieve unmatched stability and chip evacuation efficiency, even at depth-to-diameter ratios exceeding 200:1. The single flute eliminates flute interference, creating a larger cross-sectional area for chips to exit, while the internal coolant channel ensures continuous lubrication and heat removal at the cutting zone.
1. Unmatched Rigidity & Wear Resistance: The solid carbide body (1600 HV hardness) resists deformation and abrasion, outperforming HSS and brazed drills in materials like Inconel, titanium, and hardened tool steel (up to 65 HRC).
2. Single Flute Advantage: The absence of a second flute increases core thickness by 40%, reducing flexure and improving hole straightness (≤0.1mm/m deviation). The wide flute allows chips to curl and exit smoothly, preventing blockages in deep bores.
3. Precision Coolant Delivery: A polished internal coolant channel delivers high-pressure fluid (100-300 bar) directly to the cutting edge, reducing friction and thermal load. This design extends tool life by 40% compared to dual-flute models in similar applications.
4. Optimal Cutting Geometry: A 140° point angle with a reinforced web enhances penetration into tough materials, while the polished margin (0.05mm land width) ensures minimal contact with the bore wall, reducing friction and heat buildup.
5. Custom Engineered Solutions: Available in diameters from 1mm to 15mm and lengths up to 1.5 meters, with options for left-hand rotation, stepped flutes, and specialized coatings (DLC, CrN) for non-ferrous metals like copper and aluminum.
Aerospace Turbine Blades: Drills tiny cooling holes (1-3mm diameter) in nickel-based superalloys, maintaining straightness and circularity for optimal airflow and component longevity.
Medical Implants: Creates deep, smooth bores in cobalt-chromium hip stems, meeting FDA requirements for biocompatible surfaces (Ra ≤ 0.4μm) and dimensional accuracy for press-fit applications.
Precision Optics: Machines guide holes in optical lens mounts made from aluminum and glass-reinforced polymers, where even minor deviations can affect light transmission and alignment.
Semiconductor Equipment: Used for deep holes in silicon wafer processing tools, demanding ultra-high precision to avoid contamination and ensure repeatable manufacturing processes.
Firearm Barrels: Produces match-grade bores with minimal rifling distortion, leveraging the single flute’s vibration-damping properties to achieve consistent ballistic performance.
Q: Why choose a single flute over dual flute design?
A: Single flute drills offer higher rigidity and larger chip space, critical for deep holes in brittle or high-strength materials where chip jamming is a risk. Dual flute models are better for softer materials requiring faster material removal.
Q: What spindle speed is recommended for titanium alloys?
A: For Ti-6Al-4V, spindle speeds should range from 2000-4000 RPM, depending on diameter (smaller diameters use higher speeds). Always consult the tool data sheet for material-specific parameters.
Q: Can this drill be used for micro-drilling (below 1mm)?
A: Standard models start at 1mm, but custom drills for sub-1mm diameters are available with specialized grinding and coating to enhance rigidity and chip evacuation.
Q: How does the single flute affect surface finish?
A: The single flute reduces flute marks on the bore wall, resulting in smoother surfaces. Combined with a polished cutting edge, it consistently achieves Ra ≤ 0.8μm without post-processing.
Q: What tool holders are compatible with this drill?
A: It fits standard gun drill holders with cylindrical shanks (DIN 6535), the also available with HSK-E25 or BT30 interfaces for CNC machines with automatic tool changers.
