Cleveland C14225 Cobalt Screw Machine Drill Bit 29/64 in

Product Description

The CLEVELAND C14225 is a cobalt screw machine length drill bit designed for high-performance drilling in tough materials. Built to M42 cobalt steel standards, it features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The parabolic flute geometry improves chip evacuation, making it well suited for deeper holes and interrupted cuts. At 29/64 inch in diameter and 3-9/16 inches overall length, this bit fits the compact screw machine length profile, keeping deflection low in short-reach applications. Licensed trades and machining professionals are the primary users of this series.

The C14225 is built for drilling alloy steel, aluminum, and similar metals where a standard HSS bit would dull prematurely. The screw machine length format is common in drill press, CNC, and turret lathe setups where a shorter, stiffer bit improves accuracy and surface finish. The straight-cylindrical shank accepts standard drill chucks without adapters. It is a heavy-duty grade bit intended for production and repetitive drilling environments rather than occasional use.

Key Features

• M42 cobalt construction for extended tool life in alloy and abrasive materials
• 135-degree split point reduces thrust and eliminates the need for center-punching
• Parabolic flute profile promotes fast, clean chip evacuation
• Web-thinned, parallel web configuration reduces cutting resistance
• Screw machine length (3-9/16 inches OAL) provides rigidity and reduced deflection
• Meets ASME B94.11M standard; Specification Designation ANSI

Compatibility

Designed as an OEM-style screw machine length drill bit compatible with standard drill chucks accepting a 0.4531-inch straight-cylindrical shank, suitable for drill press, CNC, and turret lathe applications in metalworking environments.

Installation Notes

Installation is performed by machinists and tool-and-die professionals in machine shop or production settings. Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation, and verify chuck runout is within acceptable tolerance to protect the bit and workpiece. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
