Short Blade X-type Carbide Drill
The DP160C features an "external cooling groove + integrated stepped cutting edge" design, enabling precision machining of two different hole diameters in a single pass, while the external cooling system delivers coolant directly to the cutting zone. The high-performance guide drill has been optimized, The carefully designed dual-edge geometry provides performance and stability when drilling intersecting holes and/or drilling on sloped or irregular surfaces. The 140° acute angle and four-flute geometry enhance self-centering capability. The multi-angle triangular cutting edge ensures stability and enhances performance, while the geometric design minimizes burrs at the entry and exit points. Its geometric design minimizes burrs at the entry and exit points. The pre- and post-polishing processes reduce friction and ensure excellent chip management,

Design details engineered for accuracy, tool life and process stability.
The drill bit features a double-helix external coolant channel design, allowing the coolant to flow directly along the channels to the double-step cutting edges. This improves heat dissipation efficiency by 50% and prevents the risk of drill bit overheating during stepped hole machining.
The cutter body is machined from a single piece of ultra-fine-grain carbide (HRC 68) with no welded joints, ensuring no loosening or runout during high-speed, high-feed machining.
The DP160C series features a superior design with a long cutting edge optimized for rigidity. The cutting edge tip is designed with an R-radius for protection, and the cutting edge band is passivated. It delivers efficient and precise cutting performance for rough machining.
Optimized for alloy steel, stainless steel, nickel alloys, and other high-hardness materials to deliver best-in-class performance
Pre- and post-polishing processes reduce friction and ensure excellent chip management
