Cleveland C03003 Jobber Drill Bit Wire 27 Hss 118 Deg

Product Description

The CLEVELAND C03003 is a jobber-length drill bit in wire gauge size 27, equivalent to 0.1440 inches in decimal diameter. Manufactured from high speed steel (HSS) with a bright uncoated finish, it features a standard 118-degree split point and a fast spiral flute pattern for efficient chip evacuation. The straight-cylindrical shank measures 0.1440 inches in diameter, making it compatible with standard drill chucks. Web-thinned construction reduces thrust at the point and improves penetration. This bit is suited for general-purpose drilling and is installed by machinists, maintenance technicians, and trade professionals working with aluminum and similar non-ferrous materials.

The C03003 is designed for general-purpose applications where a wire gauge 27 diameter is required. Its 3-inch overall length and 1-7/8-inch flute length make it well suited for through-hole and blind-hole drilling in sheet metal, aluminum stock, and light fabrication work. The right-hand cutting direction is standard for conventional drill press and handheld drill motor use. This bit ships individually but is subject to a minimum order quantity of 10 units per order.

Key Features

• Wire gauge size 27 (0.1440 inches) with diameter tolerance of -0.0007 to 0.0000 inches for consistent hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Fast spiral flute design promotes chip clearing in aluminum and soft metals
• Bright uncoated HSS construction — no coating buildup to affect diameter accuracy
• Straight-cylindrical shank fits standard 3-jaw chucks without modification
• Meets ASME B94.11M and ANSI specification designation for dimensional compliance

Compatibility

Designed as an OEM-style general-purpose jobber drill bit for use in standard drill presses, handheld drill motors, and CNC drill fixtures accepting a 0.1440-inch straight-cylindrical shank. Optimized for primary use in aluminum workpieces per manufacturer specification.

Installation Notes

Install into a properly sized drill chuck and tighten securely before operation. Secure the workpiece with a clamp or vise before drilling to prevent rotation and maintain hole accuracy. Use appropriate cutting fluid or lubrication when drilling aluminum to extend bit life and improve finish quality. Inspect the cutting edges for wear or chipping before each use and replace bits that show dull or damaged geometry.
