Cleveland C15072 Screw Machine Drill Bit 13/32 in Cobalt 5pk

Product Description

The CLEVELAND C15072 is a screw machine length drill bit designed for high-performance drilling in demanding materials. Built from M42 cobalt high-speed steel, this bit handles alloy steels and aluminum where standard HSS tooling wears prematurely. The 135-degree split point reduces walking at startup and lowers thrust requirements, making it suitable for production drilling and tight-tolerance work. The parabolic flute geometry promotes efficient chip evacuation. The overall length is 3-5/16 inches with a straight cylindrical shank, making it compatible with standard drill chucks and quick-change holders. This listing contains 5 bits.

Screw machine length bits are shorter and more rigid than jobber-length bits, which reduces deflection in CNC machining centers, turret lathes, drill presses, and screw machines. The C15072 is well suited for production shops, machine shops, and industrial maintenance applications where consistent hole quality in alloy or aluminum workpieces is required. The web-thinned, parallel-web construction reduces cutting resistance and extends tool life in repetitive drilling cycles.

Key Features

• M42 cobalt steel construction for heat resistance and extended tool life in hard alloys
• 135-degree split point reduces thrust and eliminates center-punch requirements on most materials
• Parabolic flute design with web thinning improves chip evacuation and reduces cutting resistance
• Screw machine length body provides greater rigidity and reduced deflection versus jobber-length bits
• Right-hand cut with straight cylindrical shank fits standard chucks and quick-change systems
• Meets ASME B94.11M and ANSI specification standards

Compatibility

Designed for use in CNC machining centers, drill presses, turret lathes, and screw machines where a 13/32 inch straight shank drill bit is required. Primary workpiece materials are alloy steel and aluminum per Series 2175A specification.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Secure the shank fully within the chuck or collet to the minimum recommended engagement depth before operation. Do not exceed the rated spindle speed for the workpiece material and bit diameter.
