Titan USA CD32713 M Screw Machine Drill Bit, 135 deg Point, Cobalt, Gold Oxide, 6 PK

The Titan USA CD32713 is a premium cobalt high-speed steel screw machine (stub length) drill bit with a 135-degree split point and gold oxide finish, packed 6 per package. Combining the rigidity advantage of stub length with the hot hardness of cobalt steel alloy, this drill is purpose-built for production drilling in stainless steel, hardened steel, titanium, and difficult alloys on CNC machining centers, turret lathes, and screw machines. Cobalt steel maintains its cutting edge at the high temperatures these tough materials generate — where standard HSS stub drills lose hardness and fail prematurely. The shorter flute length reduces deflection and improves chip evacuation in deep-hole applications relative to flute length. The 135-degree split point self-centers without a center punch and requires less thrust, protecting both the drill and the machine spindle in hard-material drilling. Gold oxide finish aids lubricity and provides easy cobalt identification in the tool crib.

• Cobalt steel maintains cutting-edge hardness in stainless, hardened steel, and titanium where HSS fails
• Stub length maximizes rigidity — eliminates deflection and chatter in CNC and production drilling
• Purpose-built for turret lathes, screw machines, and CNC machining centers where overhang matters
• 135-degree split point self-centers without a center punch and reduces thrust on hard materials
• Gold oxide finish improves lubricity and makes cobalt bits easy to identify in the tool crib
• Multi-pack pricing suits production environments that consume stub length cobalt drills regularly
