Cleveland C14246 Cobalt Screw Machine Drill Bit Wire 6

Product Description

The CLEVELAND C14246 is a screw machine length cobalt drill bit designed for high-performance drilling in demanding metalworking applications. Built to Series 2175 specifications, it features a 135-degree split point that reduces walking and penetrates material with less thrust than a standard 118-degree point. The bit is ground from M42 cobalt high-speed steel, providing elevated heat and wear resistance suitable for hard or abrasive workpiece materials. With a wire size 6 diameter of 0.2040 inches and an overall length of 2.375 inches, this stub-length bit delivers added rigidity compared to jobber-length alternatives, making it a preferred choice for machinists and maintenance technicians working on CNC equipment, drill presses, and manual machines.

This bit is suited for drilling alloy steels and aluminum in production and job-shop environments where stub-length tools reduce deflection and chatter. The parabolic flute geometry promotes efficient chip evacuation during deeper passes, which is particularly valuable when working in stringy or chip-prone alloys. The straight cylindrical shank accepts standard drill chucks and collet holders without modification. It is a single-piece unit sold individually and intended for professional machinists, toolroom technicians, and industrial maintenance personnel.

Key Features

• M42 cobalt construction resists heat buildup when drilling alloy steel and tough aluminum alloys
• 135-degree split point with web thinning reduces entry thrust and eliminates the need for a center punch on most metals
• Parabolic flute profile with parallel web configuration improves chip flow and reduces clogging on deep passes
• Screw machine (stub) length provides greater rigidity and reduced deflection versus jobber-length bits
• Right-hand cut with straight cylindrical shank fits standard drill chucks and collet systems
• Diameter tolerance of +0.0000 to -0.0007 inches meets ASME B94.11M and ANSI standards for precision fitment

Compatibility

Designed as an OEM-style replacement or direct drop-in for wire size 6 screw machine length drill bits used in standard drill chucks and collet holders accepting a 0.2040-inch straight cylindrical shank. Primary workpiece materials listed by the manufacturer are alloy steel and aluminum.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with cutting tool speeds and feeds for cobalt tooling. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Use appropriate cutting fluid or coolant for alloy steel applications to extend tool life, noting this bit does not have coolant-through capability. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
