Cleveland C03582 Jobber Drill Bit 13/64 Inch Hss

Product Description

The CLEVELAND C03582 is a jobber-length twist drill bit designed for general-purpose drilling in metal, aluminum, and similar materials. Built from high speed steel with a bright uncoated finish, it features a 118-degree standard point angle and a slow spiral, two-flute design that promotes chip evacuation and clean hole entry. The straight cylindrical shank seats securely in standard drill chucks. At 3.625 inches overall length with a 2.4375-inch flute length, this bit fits the proportions expected of a jobber-length tool and is suited for use in hand drills, drill presses, and CNC drilling applications. It conforms to ASME B94.11M standards.

This bit is intended for drilling aluminum as its primary workpiece material, though the general-purpose grade makes it suitable for a range of soft to medium metals and plastics. The 13/64-inch diameter (0.2031 inches decimal) is a common size for pilot holes, clearance holes, and through-hole drilling in light fabrication, mechanical, plumbing, and HVAC sheet metal work. The web-thinned, tapered web configuration reduces thrust force at the point, making it easier to start holes accurately without center-punching on softer materials.

Key Features

• High speed steel construction for durability across repeated use in metal and aluminum
• 118-degree standard point angle with web-thinned tapered web for reduced entry thrust
• Slow spiral, two-flute design promotes efficient chip removal
• Bright uncoated finish suitable for general-purpose applications
• Straight cylindrical shank fits standard drill chucks without adapters
• Conforms to ASME B94.11M and ANSI specification designations

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks on hand drills, drill presses, and CNC drilling equipment accepting a 13/64-inch straight shank.

Installation Notes

Installation of this drill bit is performed by qualified tradespeople and machinists following standard safe drilling practices. Secure the shank fully in the chuck and verify runout before drilling. Always wear appropriate eye protection and secure the workpiece before operation. When drilling metal, use cutting fluid where appropriate to extend bit life and improve hole quality.
