Built from M42 cobalt high-speed steel and finished with a titanium nitride (TiN) coating, this bit delivers extended tool life and resistance to heat buildup under sustained cutting loads. The 135-degree split point starts on contact without a center punch, reducing walking on smooth or curved surfaces. With a parabolic flute design and web-thinned, tapered web configuration, the C16631 evacuates chips efficiently and maintains cutting performance through deeper holes. It measures 3.25 inches overall and weighs 0.2 pounds.\u003c\/p\u003e\n\u003cp\u003eThis bit suits machinists, fabricators, maintenance technicians, and tool-and-die professionals working with ferrous metals, stainless steel, high-strength alloys, and similar difficult-to-machine materials. The straight-cylindrical shank is compatible with standard drill chucks and quick-change systems. Right-hand cutting direction and parabolic flute geometry make it a reliable choice for production drilling in both manual and CNC-assisted setups where chip clearance and tool longevity are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for heavy-duty cutting in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends service life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point eliminates the need for center-punching and reduces drill walk\u003c\/li\u003e\n  \u003cli\u003eParabolic flute with tapered, web-thinned web improves chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard and quick-change drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe C16631 is a wire-gauge size 19 (0.1660 inches) jobber-length drill bit from the Cleveland Series 2075T, suitable for use in any drill press, hand drill, or CNC spindle accepting a straight-cylindrical shank of 0.1660 inches diameter.
