Product Details

This 2-flute solid carbide drill bit is designed for high-performance drilling in hardened steels up to HRC 55, stainless steel, cast iron, and alloy steels. The TiN (titanium nitride) coating provides reduced friction and increased wear resistance, enabling higher cutting speeds and longer tool life compared to uncoated carbide. The 2-flute design offers maximum chip clearance, making it ideal for chip evacuation in deeper holes and softer materials like aluminum.

The 14.5mm cutting diameter features a straight shank of the same diameter (14.5mm), allowing secure clamping in collet chucks. With a flute length of 56mm and overall length of 107mm, this drill is optimized for medium-depth holes in mold components, die tooling, automotive parts, and general engineering applications. The jobber-length geometry provides good rigidity for CNC machining centers and milling machines.

Typical applications include heat-treated alloy steels, stainless steel shafts, cast iron housings, and non-ferrous metals where chip evacuation is critical. Custom lengths, shank configurations, and alternative coatings (TiAlN, AlCrN) are available for OEM orders. For precision drilling in HRC55 materials, this 2-flute TiN-coated carbide drill delivers consistent hole quality and extended tool life.
