Cleveland C14626 Cobalt Screw Machine Drill Bit Wire 4

Product Description

The CLEVELAND C14626 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding industrial and metalworking applications. Built from M42 cobalt high-speed steel, this bit delivers superior heat and wear resistance compared to standard HSS tooling. It features a 135-degree split point that reduces walking and cutting pressure, enabling faster penetration with less feed force. The straight-cylindrical shank measures 0.2090 inches in diameter and fits standard drill chucks. With a heavy-duty grade rating and web-thinned geometry, this bit handles tough interrupted cuts and close-tolerance hole work that tradespeople and machining professionals encounter in production environments.

This drill bit is well suited for drilling into alloy steel and aluminum in production machining, maintenance, and fabrication settings. The screw machine length profile provides a shorter, more rigid body than jobber-length bits, making it ideal for drill press work, CNC setups, and hand-held power tools where reduced deflection matters. It conforms to ASME B94.11M and meets ANSI and DIN 1897 specifications, making it compatible with standardized tooling programs across manufacturing and mechanical contracting shops.

Key Features

• M42 cobalt construction provides elevated heat resistance for drilling hard alloys and abrasive materials
• 135-degree split point reduces thrust and eliminates center-punch requirements on most metals
• Web-thinned, parallel web configuration improves chip evacuation and cutting efficiency
• Screw machine length body increases rigidity and reduces deflection vs. jobber-length bits
• Right-hand cut with regular spiral flutes for standard clockwise drill operation
• Meets ASME B94.11M, ANSI, and DIN 1897 standards for dimensional accuracy and performance

Compatibility

Designed as a heavy-duty OEM-style replacement or direct tooling selection for applications requiring a wire gauge No. 4 (0.2090 inch) screw machine length drill bit with a straight-cylindrical shank, compatible with standard drill chucks accepting that shank diameter. Primary workpiece materials listed are alloy steel and aluminum.

Installation Notes

This bit is installed and operated by machinists, tool-and-die tradespeople, and mechanical fabricators using drill presses, CNC drilling centers, or handheld power drills with a compatible chuck. Secure the shank firmly in the chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Use cutting fluid or coolant when drilling alloy steel to extend tool life, as this bit does not support through-coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace when diameter tolerance can no longer be held within the rated range of plus 0.0000 to minus 0.0007 inches.
