Cleveland C14226 Cobalt Drill Bit 15/32 Inch 135 Point

Product Description

The CLEVELAND C14226 is a screw machine length drill bit designed for high-performance drilling in demanding shop and field environments. Built from M42 cobalt high-speed steel, this bit handles alloy steels, aluminum, and other tough workpiece materials where standard HSS tooling falls short. The 135-degree split point starts on contact without a center punch, reducing walking and improving hole accuracy. With a 15/32-inch (0.4688-inch decimal) diameter and an overall length of 3-5/8 inches, it fits standard drill chucks and is sized for stub-length rigidity. Machinists, maintenance mechanics, and fabricators reach for this bit when production drilling calls for heat resistance and edge retention.

This drill bit suits metalworking applications in manufacturing, maintenance, and fabrication settings where short, rigid tooling improves control and reduces deflection. The screw machine length profile makes it well suited for drill press work, CNC drilling operations, and hand-held power drills in tight clearance situations. Primary workpiece materials listed include alloy steel and aluminum, making it a practical choice across a range of ferrous and non-ferrous drilling tasks.

Key Features

• M42 cobalt steel construction for heat resistance and extended tool life in hard materials
• 135-degree split point reduces thrust and eliminates the need for center-punching
• Parabolic flute geometry promotes efficient chip evacuation during deep drilling passes
• Web-thinned, parallel web configuration reduces cutting resistance
• Straight-cylindrical shank (0.4688 inch) fits standard 3-jaw drill chucks without adapters
• Right-hand cut; manufactured to ASME B94.11M standards with ANSI specification designation

Compatibility

Designed as an OEM-style replacement or direct substitute for screw machine length drill bits in the 0.4500 to 0.5000 inch decimal diameter range, conforming to ASME B94.11M dimensional standards.

Installation Notes

Installation of drill bits should be performed by qualified machinists or maintenance personnel familiar with rotating cutting tool safety. Ensure the drill chuck is fully tightened and the workpiece is securely clamped or fixtured before beginning any drilling operation. Disconnect power and allow the spindle to come to a complete stop before changing tooling. Do not exceed the recommended RPM range for the workpiece material and bit diameter.
