Cleveland C15076 Drill Bit 15/32 in Cobalt Tialn 135 Pt

Product Description

The CLEVELAND C15076 is a screw machine length drill bit designed for high-performance drilling across a wide range of materials. Built from M42 cobalt high-speed steel and finished with a TiAlN (titanium aluminum nitride) coating, this bit delivers extended tool life and heat resistance in demanding production environments. The 135-degree split point starts on contact without a center punch, reducing walk and improving hole accuracy. At 15/32 inches in diameter (0.4688 inches decimal) with a 3-5/8 inch overall length, it fits standard drill chucks and machine spindles. Licensed machinists, tool-and-die workers, and maintenance technicians are the primary users of this bit.

The C15076 is suited for short-hole drilling applications where rigidity and chip evacuation matter. Its screw machine (stub) length body reduces deflection compared to jobber-length bits, making it well-matched for drill press, CNC, and manual mill operations. The parabolic flute geometry accelerates chip clearance, which is especially valuable when drilling gummy materials or deeper holes relative to diameter. This bit performs across aluminum, brass, carbon steel, cast iron, nickel alloy, plastics, stainless steel, and tool steel without coolant-through requirements.

Key Features

• M42 cobalt construction for high heat and wear resistance in hard and abrasive materials
• TiAlN coating extends cutting life and reduces friction at elevated temperatures
• 135-degree split point for self-centering entry and reduced thrust force
• Parabolic flute design promotes fast, efficient chip evacuation
• Web-thinned, parallel web configuration reduces cutting resistance
• Straight-cylindrical shank at 0.4688 inches diameter fits standard chucks without adapters
• ANSI specification designation ensures dimensional conformance

Compatibility

Designed for use with standard drill presses, CNC machining centers, and manual mills accepting a straight-cylindrical shank at 0.4688 inches. Primary workpiece materials include aluminum, brass, carbon steel, cast iron, nickel alloy, plastics, stainless steel, and tool steel. Part of the Cleveland Series 2175A screw machine drill line.

Installation Notes

This bit is installed and serviced by machinists, tool-and-die technicians, and maintenance personnel. Before mounting, verify chuck or collet capacity matches the 0.4688-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Do not exceed the recommended feed and speed ranges for the workpiece material, as overloading a cobalt bit without coolant in hard materials can lead to premature edge breakdown.
