Chicago-latrobe 44103 Jobber Length Drill Bit Size 33

Product Description

The CHICAGO-LATROBE 44103 is a jobber length drill bit sized at wire gauge 33 (0.1130 inches decimal), designed for general-purpose drilling in metal fabrication and maintenance applications. Built from high speed steel with an oxide coating, this bit delivers adequate hardness and heat resistance for production drilling in cast iron and steel. The 118-degree standard point angle suits a wide range of materials without requiring regrinding for typical shop use. At 2.625 inches overall length with a 1.5-inch flute length, it fits standard drill chucks and is handled by machinists, maintenance mechanics, and tool-and-die technicians daily.

This bit is suited for light-to-medium drilling tasks in ferrous metals including cast iron and steel. The straight-cylindrical shank seats securely in both handheld and bench drill press chucks. Its regular spiral, two-flute configuration clears chips efficiently in through-hole and blind-hole applications. Manufactured to DIN 338 standards, the Series 150 designation places it in CHICAGO-LATROBE's general-purpose line, making it appropriate for job shops, maintenance departments, and production environments where consistent, repeatable hole sizing in the 0.1000 to 0.1500 inch range is required.

Key Features

• Wire gauge size 33, 0.1130 inches decimal diameter with tight tolerance of -0.0005 to 0.0000 inches
• High speed steel construction with oxide finish for basic heat and corrosion resistance
• 118-degree standard point angle for general-purpose use in cast iron and steel
• Web-thinned, tapered web configuration reduces thrust and improves cutting efficiency
• Right-hand cut, regular spiral, two-flute design for reliable chip evacuation
• Meets DIN 338 dimensional standards for consistent fitment and performance

Compatibility

Designed as a general-purpose OEM-style jobber drill bit compatible with any standard drill press, hand drill, or CNC drilling fixture accepting a 0.1130-inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel as specified by the manufacturer.

Installation Notes

Install and remove drill bits only after the drill press or power tool has been fully de-energized and the spindle has come to a complete stop. Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation to prevent runout or slippage. Apply appropriate cutting fluid when drilling steel to extend bit life and maintain hole tolerance. Follow applicable OSHA and shop safety standards for rotating cutting tools, including proper workpiece fixturing.
