Cleveland C16792 5/16 Inch Cobalt Taper Length Drill Bit

Product Description

The CLEVELAND C16792 is a taper length cobalt drill bit designed for heavy-duty drilling across a wide range of materials. Built to Series 2575 specifications, it features a 5/16-inch (0.3125 inch) diameter with a 135-degree split point for self-centering entry and reduced walking on hard surfaces. The parabolic flute geometry promotes fast chip evacuation and cooler cutting, making it well-suited for prolonged use in demanding shop and field environments. At 6.375 inches overall length with a 4-inch flute, this bit provides extended reach over standard jobber-length drills while maintaining rigidity. Licensed machinists, millwrights, and maintenance technicians are the primary users of this tool.

This drill bit is rated for use in aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. The cobalt construction (M42 grade) gives it the heat resistance needed for tough alloys like stainless steel and nickel-based materials where high-speed steel bits tend to break down. The taper length configuration makes it a practical choice where standard jobber bits lack reach, such as drilling through structural members, heavy plate, or deep-set flanges in fabrication and maintenance applications.

Key Features

• M42 cobalt construction for superior heat and wear resistance in hard and abrasive materials
• 135-degree split point reduces thrust and eliminates center-punch requirement on most materials
• Parabolic flute design accelerates chip removal and reduces heat buildup during deep drilling
• Taper length body at 6.375 inches OAL provides extended reach over standard jobber-length bits
• Web-thinned, tapered web configuration reduces cutting resistance and improves hole entry
• Straight shank with 5/16-inch diameter fits standard drill chucks and collet holders without adapters

Compatibility

Rated for use in aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel per manufacturer material application data. Conforms to ASME B94.11M and DIN 340 standards, with specification number DIN 338.

Installation Notes

Installation and use of this drill bit is performed by machinists, millwrights, and maintenance technicians operating drill presses, magnetic-base drills, or handheld power drills. Secure the straight shank firmly in the chuck and verify runout before drilling to protect the cutting edge. Use appropriate cutting fluid or coolant for ferrous and stainless steel applications to extend tool life. Do not exceed the recommended feed and speed ranges for the workpiece material, and reduce feed pressure when the point begins to break through to avoid grab and bit damage.
