Product DescriptionProduct DescriptionPremium TiAlN Coated Carbide Drill Bits Deburring Tool for Stainless Steel and AluminumThis solid carbide tool integrates high-precision drilling and burr-free finishing, specifically engineered for stainless steel (up to 316L) and aluminum alloy (6061/7075) machining. Crafted from ultra-fine grain tungsten carbide (WC-Co alloy) with PVD-applied TiAlN nano-coating, it outperforms HSS tools by 300% in wear resistance under high-temperature conditions (up to 800°C) . Each tool undergoes 5-axis CNC grinding and CMM inspection (≤1μm concentricity) to ensure drill-to-deburr consistency—eliminating secondary operations and reducing processing costs by over 40% .Functional Description1. Material SuperiorityEngineered with a premium tungsten carbide tip or are constructed as solid carbide drills. This material is significantly harder than traditional HSS, boasting a Rockwell Hardness (HRA) of over 90, which translates to exceptional abrasion resistance and a dramatically extended tool life, even when processing the most abrasive materials.2. Engineered for CNC MachiningInternal Coolant Holes (Coolant Through): Designed for high-pressure coolant systems, these channels deliver lubricant directly to the cutting edge. It lowers cutting temperatures, improves chip evacuation, and prevents workpiece hardening, ensuring consistent performance in deep-hole drilling.Optimized Geometry: Many of our drills feature a 3-flute design or a 135-degree split point. The multiple flutes enhance stability, improve hole quality, and allow for higher feed rates.Coatings: Select models are enhanced with TiAlN (Titanium Aluminum Nitride) or other PVD coatings. These coatings provide a super-hard, heat-resistant layer that reduces friction, increases lubricity, and further boosts wear resistance, making them ideal for high-temperature alloys.3. Expanded Application RangeFor stainless steel, cast iron, titanium, and hardened steel (up to HRC 60+), our carbide drills are also the superior choice for a wider range of challenging substrates, including:Abrasive Composites: Carbon fiber, fiberglass.High-Temperature Alloys: Inconel, Waspaloy.Non-Ferrous Metals: Aluminum, copper, and brass.4. Benefits & Economic ValueCapable of operating at 2-3x the speed and feed rates of HSS drills, drastically reducing cycle times.Achieve tighter tolerances, better surface finishes, and straighter holes with minimal burring.Exceptional durability means fewer tool changes, leading to increased machine uptime and lower long-term tooling costs.A single, high-quality carbide drill can often replace multiple dedicated tools for different materials.Key Features & Benefits1. Premium Material: Made of solid tungsten carbide for maximum hardness and resistance to abrasion .2. Advanced Coating: Available with TiAlN coating or other options like TiCN and TiN , which enhance surface lubrication, reduce heat buildup, and significantly extend tool life.3. Spiral Flute Design: The multi-tooth spiral geometry enables smooth cutting action, excellent chip evacuation, and a superior finish on the workpiece .4. Versatile Adaptation: Suitable for dry/wet machining and compatible with CNC mills, lathes, and gear machines.5. Versatile Application: Capable of chamfering and deburring both the front and back sides of drilled holes, including deep and hard-to-reach areas .6. Rigid CNC Setup: Designed for use in highly rigid setups like CNC machines to prevent breakage and ensure optimal performance .7. Efficient Cutting: 2-16 flutes design (3-flute standard) enables high feed rates (up to 0.01mm/rev for steel) and smooth chip evacuation. 8. Extended Durability: Special carbide grade with fracture toughness resists chipping, doubling tool life in hardened steel (up to 65 HRC). 9. Precision Control: Chamfer angles (30°/45°/60°/90°) with ±1° tolerance; diameter accuracy up to ±0.5μm .Carbide Tap and Drill BitsCBN/PCD InsertsDrilling BitsISO Turning InsertsSide & Face Milling InsertsGrooving & Parting-off InsertsSmall Parts MachiningThreading InsertsSquare Shoulder Milling InsertsSpecificationParameterSpecificationBlade DiameterAvailable in a range from Φ3.0mm to Φ12.0mmShank Diameter3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm (corresponding to blade size)Total Length39mm to 84mm (varies with diameter)Head Length12mm to 42mm (varies with diameter)Chamfering Amounte.g., 1.5mm (for a Φ6.0mm blade)Tip Angle90° (Standard)Flute NumberOptions of 2 or 4 flutes are availableCoating TypesTiAlN, AlTiN, TiCN, TiN, or UncoatedWork MaterialCarbon Steel, Stainless Steel, Cast Iron, Aluminum, Titanium Alloy, etc.Packing & DeliveryPrepare the insertsPackaging into the boxShipping into the containerCompany ProfileOur company was founded in March 2010 with a registered capital of 30 million RMB.
