DRILLSTAR CARBIDE TOOLS ARE WORKING IN MANY PLACES AROUND THE WORLD
Our High Rigidity Solid Carbide Gun Drills represent the pinnacle of deep hole drilling technology, engineered to tackle the most challenging materials and extreme depth-to-diameter ratios with unmatched stability and precision. Built from premium-grade solid carbide (ISO K10-K30), these drills feature a reinforced core design that increases rigidity by 25% compared to standard solid carbide drills, making them ideal for applications where tool deflection and vibration are critical concerns.
Designed for holes with depth-to-diameter ratios up to 150:1, the drills incorporate advanced flute and point geometries optimized for aggressive machining while maintaining hole straightness (≤ 0.05mm/m deviation) and surface finish (Ra ≤ 0.6μm). Whether used in CNC machining centers, transfer lines, or automated production cells, these drills deliver consistent performance, reducing downtime and improving overall machining efficiency.
1. Reinforced Core Structure: A thicker web and reduced flute volume enhance torsional stiffness, minimizing flex during deep penetration. This design is particularly beneficial when machining hard materials (up to 65 HRC) or large-diameter holes where axial forces are high.
2. Optimized Chip Control: Wide, spiral flutes with variable pitch prevent chip jamming by guiding swarf efficiently out of the hole. Combined with internal high-pressure coolant channels (up to 100 bar), this feature ensures continuous machining without interruptions for chip removal.
3. Superior Heat Resistance: The drills’ substrate is treated with a dual-layer coating (TiCN base + AlCrN topcoat) that offers excellent thermal barrier properties, allowing operation at elevated temperatures (up to 1,200°C) without compromising edge integrity.
4. Precision Ground Cutting Edges: Laser-guided grinding ensures symmetrical cutting edges with micro-level precision, reducing radial forces and improving hole roundness. This precision is critical for applications requiring interchangeable components or tight fit tolerances.
1. Heavy-Duty Industrial Machinery: Used in drilling deep holes for hydraulic cylinders, crane booms, and mining equipment components, where holes must withstand high mechanical stress and corrosive environments.
2. Aerospace Structural Parts: Essential for machining deep attachment holes in aircraft fuselage sections and wing spars, especially in composite-metal stacks where tool stability is key to avoiding delamination.
3. Energy Equipment Manufacturing: Employed in drilling deep holes for nuclear reactor components, wind turbine shafts, and offshore pipeline valves, ensuring structural integrity under extreme pressure and temperature variations.
4. Defense and Ordnance: Critical for producing artillery barrels and missile components, where hole straightness and surface finish directly impact projectile accuracy and reliability.
5. High-Precision Tooling: Used in creating deep holes for jigs, fixtures, and gauges, where dimensional consistency is required across thousands of machining cycles.
