Chicago-latrobe 47366 Jobber Drill 14.50mm Hss 118 Deg

Product Description

The CHICAGO-LATROBE 47366 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metalworking applications. It measures 14.50 mm (0.5709 inches) in diameter with a standard 118-degree point angle and a black oxide coating that reduces friction and provides moderate corrosion resistance. The overall length is 169.00 mm (6.65 inches), with a flute length of 114.00 mm (4.49 inches). The tapered web with web-thinning reduces thrust at the cutting edge and improves chip evacuation. This bit is used by machinists, maintenance mechanics, and metal fabricators working in production and job-shop environments.

The 47366 is suited for drilling steel and cast iron in general-purpose industrial and maintenance applications. Its straight cylindrical shank is compatible with standard drill chucks on bench drill presses, handheld power drills, and CNC machining centers equipped with appropriate chuck tooling. The regular spiral flute geometry handles a broad range of ferrous materials without requiring specialized tooling setup. Typical uses include through-hole and blind-hole drilling in plate stock, structural steel, and cast iron components where tight tolerances are not the primary requirement.

Key Features

• 14.50 mm (0.5709 inch) diameter, falling within the 12.50 mm to 15.00 mm size range of the Series 150 line
• 118-degree standard point angle for general-purpose entry into steel and cast iron
• Black oxide coating reduces friction and provides light corrosion protection during storage and use
• Web-thinned tapered web lowers drilling thrust and improves chip clearing
• Right-hand cutting, regular spiral flute geometry compatible with conventional drill press and handheld setups
• Conforms to DIN 338 specification for jobber-length drills

Compatibility

Designed for use in standard drill chucks accepting straight cylindrical shanks. Primary workpiece materials are steel and cast iron. Suitable for general-purpose drilling where DIN 338 jobber-length geometry is specified.

Installation Notes

Secure the shank fully in the drill chuck and verify concentricity before beginning a cut. Use cutting fluid or coolant appropriate for the workpiece material to extend tool life, particularly in steel. Ensure the workpiece is firmly clamped before drilling to prevent movement and bit deflection. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
