Cleveland C14587 Cobalt Screw Machine Drill Bit Size 24

Product Description

The CLEVELAND C14587 is a cobalt screw machine length drill bit sized at wire gauge 24 (0.1520 inch diameter) with a 135-degree split point and web-thinned geometry. Built from M42 cobalt high-speed steel, it delivers the heat resistance and edge retention needed for production drilling in tough materials. The right-hand cut, straight-cylindrical shank and shortened screw machine length body are designed for rigid setups where a standard jobber bit would flex or chatter. Licensed machinists, tool-and-die shops, and industrial maintenance technicians are the primary users of this bit type.

This bit is suited for drilling alloy steels and aluminum in screw machine, turret lathe, and CNC drilling applications where a shortened overall length of 2-1/16 inches provides extra rigidity and reduced deflection. The 1-inch flute length and parallel web configuration support chip evacuation in close-clearance fixtures and multi-spindle setups. It conforms to ASME B94.11M and meets both ANSI and DIN 1897 specification designations, making it appropriate for shops that hold production drilling to published dimensional standards.

Key Features

• M42 cobalt construction for heat resistance in hard and abrasive workpiece materials
• 135-degree split point with web thinning reduces thrust force and improves self-centering
• Screw machine length body at 2-1/16 inches overall for maximum rigidity in fixed setups
• Right-hand cut, straight-cylindrical shank at 0.1520 inch diameter fits standard collets and drill chucks
• Regular spiral with 2 flutes and parallel web configuration promotes consistent chip flow
• Diameter tolerance held to +0.0000 to -0.0007 inch for repeatable hole sizing
• Heavy-duty grade rated for alloy steel and aluminum primary workpiece materials

Compatibility

Designed as a screw machine length replacement drill bit for use in standard drill chucks, collet holders, and multi-spindle heads accepting a 0.1520-inch straight-cylindrical shank, consistent with wire gauge 24 tooling in ASME B94.11M and DIN 1897 compliant applications.

Installation Notes

Installation is performed by machinists and CNC setup technicians. Always power down and lock out the machine before seating or removing the bit from the chuck or collet. Confirm shank seating depth and runout with an indicator before production drilling begins. Do not exceed the speed and feed parameters recommended for the workpiece material and cobalt tooling grade.
