Product Details
Industrial Solid Carbide Coolant-Through Twist Drill Bit
Unleash High-Feed CNC Machining with Ultimate Thermal Control and Precision
Engineered strictly for high-performance CNC machining centers, the Coolant-Through Solid Carbide Drill Bits from Shanghai Daoge Xiaoman Tools Co., Ltd. are built to dominate the most demanding production environments. Crafted from ultra-fine grain Microcrystalline Tungsten Steel (Hardness exceeding HRA92), these bits offer a 30% increase in wear resistance over standard carbide. The defining feature is the Efficient Internal Cooling System. Dual microporous coolant channels run the entire length of the drill, delivering high-pressure coolant directly to the cutting edge. This rapidly dissipates cutting heat, blasts away chips, and prevents workpiece thermal deformation. The optimized structural design also acts as a vibration dampener, reducing machining noise by 15-20dB and delivering a mirror-like hole wall finish of Ra ≤ 0.8µm. Perfect for continuous, high-efficiency processing of stainless steel, titanium alloys, and hardened cast iron. Available for global OEM distribution with a wide range of specialized coatings (AlTiN, TiAlN, TiSiN, DLC, etc.).
Key Technical Advantages
- Internal Coolant Delivery: Eliminates the traditional problem of poor chip evacuation and overheating in deep holes. High-pressure coolant forces chips back up the flutes instantly, drastically extending tool lifespan.
- Ultra-Fine Tungsten Carbide: The HRA92+ base material supports extreme rotational speeds (200m/min or higher) and high-feed machining, dramatically reducing cycle times and frequent tool replacement costs.
- Precision Hole Quality: The rigid solid carbide construction combined with optimized cutting geometry suppresses vibration, achieving exceptionally tight tolerances and a smooth Ra ≤ 0.8µm finish, often eliminating the need for a secondary reaming pass.
- High-Performance Custom Coatings: We match the coating to your material. Our standard bronze-tinted AlTiN/TiSiN coatings are unparalleled for high-heat steel and titanium machining, while we offer specialized DLC (Diamond-Like Carbon) coatings for aluminum applications.
- Direct OEM Manufacturing: We supply the world's leading cutting tool brands. Packaged safely in individual PP tubes, we offer complete customization of cutting diameters, flute lengths, and shank configurations to match your exact CNC setup.
