Cleveland C14824 Cobalt Screw Machine Drill Bit 0.1575 in

Product Description

The CLEVELAND C14824 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding production and maintenance environments. Built to an overall length of 2.165 inches with a cutting diameter of 0.1575 inches, this bit is engineered for precision and durability. The 135-degree split point reduces walking and allows penetration without a center punch on most materials. The web-thinned, parallel web configuration reduces thrust requirements and improves chip evacuation. Manufactured from M42 heavy-duty cobalt high-speed steel, the C14824 handles heat and wear better than standard HSS bits, making it suited to interrupted cuts and difficult materials.

This bit is intended for use in screw machine, turret lathe, and CNC drilling applications where a short, rigid tool is required to minimize deflection. Its primary workpiece materials are alloy steels and aluminum, though the cobalt construction extends capability to harder ferrous materials encountered in production shops, tool rooms, and maintenance facilities. A right-hand cut with a regular spiral and two flutes supports efficient chip clearing in through-hole and blind-hole drilling. Licensed machinists, toolroom technicians, and production drillers are the typical installers and users.

Key Features

• M42 cobalt construction rated for heavy-duty grade service with superior heat and wear resistance
• 135-degree split point reduces thrust and eliminates walking on entry
• Web-thinned parallel web lowers cutting resistance and improves chip flow
• Screw machine length body provides added rigidity and reduced deflection compared to jobber-length bits
• Right-hand, two-flute regular spiral flute design for efficient chip evacuation
• Diameter tolerance held to +0.0000 to -0.0007 inches for consistent, accurate hole sizing

Compatibility

Designed as an OEM-style replacement or direct procurement option for screw machine length drill bit applications requiring a 0.1575-inch diameter cobalt bit conforming to ASME B94.11M, DIN 1897, and ANSI or DIN specification designations. Fits standard straight-cylindrical shank chucks and collet holders accepting a 0.1575-inch shank diameter.

Installation Notes

This bit is installed by machinists and toolroom professionals in drill presses, screw machines, turret lathes, and CNC machining centers using a compatible straight-shank chuck or collet. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use, as a damaged cobalt bit can produce oversized or out-of-round holes.
