Cleveland C15935 Cobalt Jobber Drill Bit No. 14 135 Deg

Product Description

The CLEVELAND C15935 is a cobalt jobber-length drill bit in No. 14 wire size (0.1820 inch decimal diameter), designed for heavy-duty drilling in superalloys, stainless steel, and other hard-to-machine materials. Built to M42 cobalt high-speed steel grade, this bit delivers superior heat and wear resistance compared to standard HSS tooling. The 135-degree split point reduces thrust and self-centers on the workpiece without a pilot hole. An oxide coating provides added lubricity and surface protection during high-temperature cutting operations. This is a professional-grade cutting tool for machinists, maintenance technicians, and metalworking trades.

This bit is engineered for drilling superalloys and hard ferrous metals in production and maintenance environments. Its fast spiral flute geometry promotes chip evacuation in deep-hole applications. At 3-3/8 inches overall length with a 1-1/8 inch flute length, it is sized for standard jobber-length applications in benchtop drill presses, CNC drilling, and handheld power drills. The straight-cylindrical shank at 0.1820 inch diameter fits standard 3-jaw chucks without an adapter. This bit is sold individually and suits shops that need single-unit replenishment of precision wire-size tooling.

Key Features

• M42 cobalt HSS construction for heat resistance in superalloy and hard-metal drilling
• 135-degree split point reduces thrust and eliminates the need for a center punch on most metals
• Oxide coating improves lubricity and extends tool life under high cutting temperatures
• Fast spiral flute design promotes efficient chip evacuation in deep holes
• Web-thinned, tapered web configuration reduces cutting resistance at the drill tip
• Meets ASME B94.11M and NAS specification standards for jobber-length drill bits

Compatibility

Designed as a heavy-duty OEM-style replacement or direct-use jobber drill bit for applications requiring No. 14 wire size (0.1820 inch) within the 0.1500 to 0.2000 inch drill bit size range. Fits any standard 3-jaw drill chuck accepting a straight-cylindrical shank. Suitable for use in drill presses, CNC drilling machines, and portable power drills in metalworking and maintenance applications.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with metal-cutting operations. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before drilling. Always wear appropriate eye protection and follow applicable shop safety standards when operating rotary cutting tools. Coolant-through is not supported by this bit; use an appropriate cutting fluid applied externally when drilling superalloys or stainless steel to extend tool life.
