Product Specifications:
This solid tungsten carbide twist drill bit is coated with TiN (titanium nitride), offering reduced friction and increased wear resistance for drilling in cast iron, carbon steel, alloy steel, and hardened materials up to HRC 68. The 16.5mm cutting diameter with a 73mm flute length and 123mm overall length makes it suitable for general-purpose drilling in CNC machining centers, milling machines, and manual drilling applications.
The TiN coating (gold) allows higher cutting speeds and extends tool life compared to uncoated carbide, particularly in abrasive materials like cast iron and hardened steels. The straight shank (18mm) fits standard hydraulic and collet chucks. This jobber-length drill provides a good balance of rigidity and reach for most industrial hole-making tasks.
Typical applications include cast iron engine blocks, hardened steel molds, heavy equipment components, and automotive parts. Custom lengths, shank diameters, and alternative coatings (TiAlN, AlCrN) are available for OEM orders. For high-volume production, this TiN-coated carbide drill delivers consistent hole quality and long 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.
