Cleveland C14726 Screw Machine Drill Bit 15/32 in Cobalt

Product Description

The CLEVELAND C14726 is a screw machine length cobalt drill bit designed for high-performance drilling in demanding shop and field applications. Built from M42 cobalt steel, this bit runs a 15/32 inch (0.4688 inch) diameter with a 135-degree split point that self-centers and reduces walking on contact. Overall length is 3-5/8 inches, making it a compact stub-length tool suited for work in tighter clearances than a jobber-length bit allows. The straight cylindrical shank fits standard drill chucks without adapters. Two spiral flutes with web thinning improve chip evacuation and reduce thrust when drilling alloy steels, aluminum, and similar materials.

This bit is intended for machinists, maintenance technicians, and metalworking tradespeople who drill into ferrous and non-ferrous metals under production or maintenance conditions. The screw machine length format is common in drill press setups, CNC machines, and hand-held drill applications where stub rigidity reduces deflection. Primary workpiece materials listed by the manufacturer include alloy steel and aluminum. The heavy-duty grade and M42 material grade make it appropriate for harder alloys that would prematurely wear standard HSS bits.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in alloy and harder metals
• 135-degree split point self-centers and reduces required thrust force
• Web-thinned parallel web reduces cutting resistance and improves chip flow
• Screw machine (stub) length at 3-5/8 inches OAL provides added rigidity and reduced deflection
• Right-hand cut with regular spiral and 2-1/8 inch flute length
• Meets ASME B94.11M and DIN 1897 (ANSI/DIN) standards
• Diameter tolerance held to +0.0000 to -0.0010 inches for precise hole sizing

Compatibility

Designed as an OEM-style replacement or direct-use screw machine length drill bit for standard straight-shank drill chucks in drill presses, CNC drilling operations, and hand-held drills requiring a 15/32 inch diameter hole in alloy steel or aluminum workpieces.

Installation Notes

Installation is performed by machinists or qualified maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck and verify concentricity before running the spindle. Ensure the workpiece is clamped firmly before drilling to prevent movement. Follow applicable shop safety standards for eye protection and chip control when drilling metal.
