Cleveland C14559 Cobalt Drill Bit Wire 37 0.1040 in

Product Description

The CLEVELAND C14559 is a cobalt screw machine length drill bit designed for high-speed drilling in tough materials. Built to ASME B94.11M and DIN 1897 standards, this heavy-duty bit carries an M42 cobalt material grade and a 135-degree split point that reduces walking and decreases thrust force on entry. The straight-cylindrical shank measures 0.1040 inches in diameter, matching the wire size 37 drill diameter. With a web-thinned, parallel-web configuration and two right-hand spiral flutes, it removes chips efficiently and maintains cutting edge integrity across repeated use cycles. Licensed HVAC techs, machinists, and metalworking professionals rely on this bit for precision hole making in close-tolerance applications.

This drill bit is suited for drilling into alloy steels and aluminum in production and maintenance environments. The screw machine length format — shorter overall length than jobber bits — provides added rigidity, making it a practical choice for drill press, CNC, and hand-drill applications where deflection must be minimized. The cobalt construction handles elevated cutting temperatures without sacrificing hardness, which is critical when working through hard alloys at sustained feed rates.

Key Features

• M42 cobalt construction handles high cutting temperatures in alloy and aluminum stock
• 135-degree split point reduces thrust and eliminates center-punch marking on most metals
• Web-thinned parallel web improves chip evacuation and reduces heat buildup at the cutting edge
• Screw machine length (1-13/16 inches OAL) provides greater rigidity than standard jobber-length bits
• Right-hand cut with two spiral flutes; no coolant-through requirement
• Meets ASME B94.11M and DIN 1897 (ANSI and DIN) specifications

Compatibility

Designed as an OEM-style screw machine length drill bit suitable for use in standard straight-shank chucks on drill presses, CNC drilling machines, and hand drills accommodating a 0.1040-inch shank diameter.

Installation Notes

Installation of this bit requires a compatible chuck capable of accepting a straight-cylindrical shank. Secure the shank fully in the chuck before operation and verify runout before production drilling. Always wear appropriate eye protection and secure the workpiece firmly before drilling. Follow applicable OSHA and shop safety standards for rotating cutting tools.
