Titan USA CD30323 Stub Length Drill Bit, W Dia, 135 deg, HSS, Black Oxide, 6 PK

The Titan USA CD30323 is a high-speed steel stub length (screw machine) drill bit with a 135-degree split point and black oxide finish, packed 6 per package. Stub length drills are shorter than standard jobber length, providing maximum rigidity and minimum deflection for precision drilling on CNC machining centers, turret lathes, automatic screw machines, and any setup where tool overhang and deflection must be controlled. The shorter flute length also improves chip control and reduces chatter tendency compared to longer jobber drills. The 135-degree split point self-centers on the workpiece surface without requiring a center punch, and requires less thrust force than a 118-degree conventional point — reducing both operator fatigue and spindle wear in high-cycle drilling operations. Black oxide finish improves surface lubricity and provides moderate corrosion resistance for extended tool life in everyday shop conditions. HSS construction delivers the toughness and economy appropriate for general production drilling in steel, aluminum, and non-ferrous materials. Multi-pack pricing supports high-consumption production environments and maintenance operations.
