Cleveland C14219 Screw Machine Drill Bit 23/64 in Cobalt

Product Description

The CLEVELAND C14219 is a screw machine length drill bit engineered for high-performance drilling in demanding shop and field applications. Built from M42 cobalt high-speed steel, it handles heat and wear better than standard HSS bits, making it well suited for hard or abrasive materials. The 135-degree split point starts on contact without a center punch and reduces walking on entry. Overall length is 3-1/16 inches with a 1-3/4-inch parabolic flute. This bit is specified by machinists, tool-and-die tradespeople, and industrial maintenance technicians who need consistent hole quality at production pace.

The C14219 is used in screw machine, drill press, and CNC drilling operations where a stub-length bit is preferred for rigidity. Primary workpiece materials include alloy steel and aluminum. The parabolic flute geometry promotes efficient chip evacuation in both through-hole and blind-hole applications. The straight cylindrical shank fits standard drill chucks without modification, making setup fast across common machine platforms in residential, commercial, and industrial maintenance environments.

Key Features

• M42 cobalt construction for extended tool life in hard and abrasive materials
• 135-degree split point reduces thrust and eliminates center-punch requirement
• Parabolic flute geometry promotes rapid chip evacuation
• Web-thinned, parallel web configuration reduces cutting resistance
• Screw machine (stub) length provides added rigidity over jobber-length bits
• Meets ASME B94.11M standard; ANSI specification designation

Compatibility

Designed as a screw machine length replacement drill bit for use in standard drill chucks, screw machines, drill presses, and CNC drilling setups where a 23/64-inch diameter, straight cylindrical shank bit is required.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools and applicable machine safety procedures. Ensure the spindle is fully stopped and the machine is de-energized or locked out before changing tooling. Secure the shank fully in the chuck and verify concentricity before drilling. Do not exceed the rated speed range for the workpiece material and bit diameter.
