Product Specifications:
This TiAlN-coated solid carbide twist drill bit is engineered for high-performance drilling in hardened steels up to HRC 55, stainless steel, cast iron, and alloy steels. The TiAlN (titanium aluminum nitride) coating provides exceptional heat resistance (up to 800°C) and low friction, enabling higher cutting speeds and longer tool life compared to uncoated or TiN-coated carbide drills.
The 13.2mm cutting diameter with a 60mm flute length and 107mm overall length is optimized for medium-depth holes in mold bases, die components, hydraulic manifolds, and automotive parts. The straight shank (14mm) ensures secure clamping in collet chucks and hydraulic holders. The jobber-length design provides good rigidity for general-purpose drilling on CNC machining centers and milling machines.
Typical applications include heat-treated alloy steels, stainless steel shafts, cast iron engine blocks, and general engineering components. Custom lengths, shank configurations, and alternative coatings (AlCrN, DLC) are available for OEM orders. For precision drilling in HRC55 materials, this TiAlN-coated carbide drill delivers consistent hole quality and extended tool life.
Solid carbide drills for automotive manufacturing deliver high precision, excellent wear resistance, and high cutting speeds. Ideal for engine cylinders, oil/cooling holes, transmission housings, brake systems, and e‑motor components.
