Cleveland C14218 Screw Machine Drill Bit 11/32 in Cobalt

Product Description

The CLEVELAND C14218 is a cobalt screw machine length drill bit designed for high-speed metal drilling in demanding shop and field applications. Built to Series 2175 standards, it features a 135-degree split point that reduces walking and allows for fast penetration without a center punch. The parabolic flute geometry promotes efficient chip evacuation, making it well suited for deep-hole work in tough materials. The web-thinned, parallel web construction reduces thrust force at the cutting edge. This bit is sized at 11/32 inches in diameter with a 3-inch overall length and a straight-cylindrical shank, and it is intended for use by machinists, maintenance technicians, and trade professionals working with metal stock.

The C14218 is rated for drilling into alloy steels and aluminum and performs in applications where standard high-speed steel bits wear prematurely. The screw machine length format — shorter than a jobber bit — provides added rigidity and is a preferred choice for lathe turrets, CNC machining centers, and drill press setups where runout and deflection must be minimized. Right-hand cutting direction matches standard chuck rotation on most stationary and portable drilling equipment.

Key Features

• Cobalt construction (M42 material grade) resists heat buildup in hard and abrasive materials
• 135-degree split point reduces thrust and eliminates the need for center punching on most metals
• Parabolic flute design improves chip flow and reduces clogging during deep cuts
• Web-thinned parallel web lowers cutting resistance and extends tool life
• Screw machine length body adds stiffness versus jobber-length bits, reducing deflection
• Straight-cylindrical shank fits standard 3-jaw chucks and collet-style holders without adapters
• Meets ASME B94.11M and ANSI specification designation requirements

Compatibility

Designed as a heavy-duty OEM-style replacement or direct-use cobalt drill bit for applications involving alloy steel and aluminum workpieces where screw machine length tooling is specified.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Always wear appropriate eye and face protection when drilling metal. Do not exceed the recommended feed rate or spindle speed for the workpiece material, and allow the bit to cool or use appropriate cutting fluid to manage heat in cobalt tooling.
