Cleveland C14561 Cobalt Screw Machine Drill Bit Wire 36

Product Description

The CLEVELAND C14561 is a cobalt screw machine length drill bit sized to wire gauge 36, equivalent to 0.1065 inches in diameter. Built on the Series 2133 platform to ASME B94.11M and DIN 1897 standards, this M42 cobalt bit is engineered for heavy-duty drilling in demanding materials. The 135-degree split point reduces walking at entry and lowers thrust force, making it well suited for production drilling environments. Overall length is 1-13/16 inches, with a 13/16-inch flute length and a 1-inch straight cylindrical shank. Diameter tolerance is held to +0.0000 to -0.0005 inches for consistent, repeatable hole size.

This bit is designed for drilling into alloy steels and aluminum in high-volume or production settings where a short, rigid drill is preferred over jobber-length tooling. Screw machine length drills reduce deflection and chatter in CNC machining centers, drill presses, and turret lathes. The right-hand cut, two-flute spiral configuration supports efficient chip evacuation in both ferrous and non-ferrous materials. It is commonly used by machinists, tool-and-die shops, and production facilities where tight tolerances and material hardness demand a premium cutting grade.

Key Features

• M42 cobalt construction provides heat and wear resistance for drilling alloy steel and aluminum
• 135-degree split point reduces drill walk and lowers required thrust at entry
• Screw machine (stub) length body increases rigidity and minimizes deflection
• Web-thinned, parallel web geometry improves chip flow and cutting efficiency
• Diameter tolerance of +0.0000 to -0.0005 inches ensures consistent hole sizing
• Meets ASME B94.11M and DIN 1897 specifications for dimensional conformance

Compatibility

Designed as a heavy-duty OEM-style replacement or direct-use screw machine drill bit for applications requiring wire gauge 36 (0.1065 inch) hole diameters in alloy steel and aluminum workpieces.

Installation Notes

This bit is installed and used by machinists and toolroom professionals in standard drill press, CNC machining center, or turret lathe chuck systems accepting a 0.1065-inch straight cylindrical shank. Ensure the spindle and chuck are fully stopped before changing or seating the bit. Verify workpiece is securely fixtured before drilling to prevent movement at entry. Coolant-through is not supported on this bit, so surface-applied cutting fluid is recommended when drilling alloy steel.
