Cleveland C15264 Cobalt Drill Bit 9/32 Inch 135 Point

Product Description

The CLEVELAND C15264 is a screw machine length drill bit designed for high-productivity drilling in demanding shop and field applications. Built from M42 cobalt high-speed steel with a TiCN (titanium carbonitride) coating, it delivers strong wear resistance and heat tolerance compared to standard HSS tooling. The bit measures 9/32 inch (0.2812 inch) in diameter with a 2-11/16 inch overall length and a 1-1/2 inch flute length. The 135-degree split point reduces walking and allows faster penetration with less feed pressure. Machinists, tool-and-die workers, and maintenance technicians use this bit in both manual and CNC drilling setups.

The C15264 is suited for drilling aluminum, brass, carbon steel, cast iron, nickel alloy, plastics, stainless steel, and tool steel. Its screw machine length profile fits standard drill chucks and CNC turrets where a shorter, stiffer bit reduces deflection in tight clearance or high-cycle applications. The parabolic flute geometry promotes efficient chip evacuation, making it effective in deep-hole and interrupted-cut conditions across both production and maintenance environments.

Key Features

• M42 cobalt steel construction for elevated heat and wear resistance
• TiCN coating reduces friction and extends tool life on hard and abrasive materials
• 135-degree split point minimizes walking and lowers required feed force
• Parabolic flute profile improves chip evacuation in deep drilling
• Web-thinned, parallel web configuration for consistent cutting geometry
• Straight-cylindrical shank fits standard 3-jaw chucks and collet holders

Compatibility

Designed as a screw machine length replacement drill bit in the Cleveland Series 2175N, suited for use across a wide range of materials including aluminum, brass, carbon steel, cast iron, nickel alloy, plastics, stainless steel, and tool steel per ANSI specification designation.

Installation Notes

Install in a properly sized drill chuck or collet that matches the 0.2813-inch straight-cylindrical shank. Ensure the workpiece is securely clamped before drilling. Use appropriate cutting fluid or coolant for the workpiece material, noting this bit does not support through-coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace when tolerance or surface finish degrades.
