Why buyers pick this one

Optimized 3D & 5D Geometries: Tailored flute lengths to match your exact machining depth requirements (3x or 5x the drill diameter). This maximizes tool rigidity and prevents deflection during deep-hole operations.
Dual Internal Coolant Channels: Solves the biggest challenge in CNC deep drilling. Through-coolant design ensures immediate chip evacuation and extends tool life by keeping the cutting edges cool under heavy loads.
140° High-Feed Point Angle: The exceptionally flat 140-degree point is designed for rigid CNC setups. It provides excellent self-centering capabilities, distributing the cutting force evenly to allow for significantly higher feed rates.
HRC 60 Tungsten Carbide Substrate: The micro-grain solid carbide foundation delivers incredible hardness, maintaining a razor-sharp edge even when machining tough, high-silicon metals that would rapidly degrade HSS tools.
Advanced Thermal Coating: The specialized bronze-colored coating acts as a high-temperature shield, reducing friction and preventing material welding (built-up edge) during high-speed rotation.

Overview

Push your CNC machining centers to their absolute limits. The Coolant-Through Solid Carbide Drill Bits from Shanghai Daoge Xiaoman Tools Co., Ltd. are engineered for high-speed, continuous production in abrasive and hardened materials. Manufactured from ultra-premium Tungsten Steel Hard Alloy rated at HRC 60, these drills offer extraordinary rigidity and wear resistance. Available in precision 3D and 5D depth-to-diameter ratios, they are specifically designed to bore deep, accurate holes without the need for constant pecking. The integrated Internal Cooling Channels force high-pressure cutting fluid directly to the cutting zone, instantly blasting chips up the flutes and preventing catastrophic thermal buildup. Featuring an aggressive 140-degree Drill Tip Angle, this tool eliminates the need for pilot holes, allowing for rapid plunging into cast iron, ductile iron, high-silicon aluminum, and copper alloys. Supplied in protective plastic tubes, these bits are ready for global OEM distribution.
