Hertel C.402.1300 Jobber Drill 13mm Hss Oxide

Product Description

The HERTEL C.402.1300 is a general-purpose jobber-length drill bit designed for metal fabrication, maintenance, and production drilling applications. It is manufactured from high speed steel with an oxide coating that reduces friction and provides moderate corrosion resistance during cutting operations. The bit measures 13.00 mm (0.5118 inches) in diameter with a 118-degree standard point angle, a two-flute right-hand spiral configuration, and a straight-cylindrical shank for use in standard drill chucks. Overall length is 152 mm (5.98 inches) with a flute length of 114 mm (4.49 inches). This type of bit is commonly installed and used by machinists, maintenance technicians, and general tradespeople across a wide range of drilling tasks.

The C.402.1300 is suited for drilling through mild steel, aluminum, wood, and similar general-purpose materials in both shop and field environments. Its straight-cylindrical shank accepts standard three-jaw drill chucks on benchtop drill presses, handheld power drills, and CNC-style machines that accommodate straight-shank tooling. The 13.00 mm diameter falls within the 12.50 to 15.00 mm size range, making it a practical choice for applications that require a half-inch-class hole without metric-to-imperial conversion compromises.

Key Features

• 13.00 mm (0.5118 inch) diameter for half-inch-class drilling without imperial sizing compromise
• 118-degree standard point angle compatible with general-purpose drilling in a wide range of materials
• High speed steel construction provides toughness and re-sharpenability
• Oxide coating reduces friction and offers light protection against corrosion and heat
• Right-hand spiral flute evacuates chips efficiently during drilling
• Straight-cylindrical shank fits standard three-jaw chucks on most drill presses and handheld tools

Compatibility

Designed as a general-purpose jobber drill compatible with any drill press, handheld power drill, or machine tool equipped with a standard three-jaw chuck capable of accepting a straight-cylindrical shank in the 12.50 to 15.00 mm size range.

Installation Notes

This drill bit is installed and used by machinists and qualified tradespeople. Secure the straight-cylindrical shank fully into the chuck before beginning any drilling operation. Always power down and de-energize the drill press or machine tool before changing bits. Use appropriate cutting fluid or coolant for extended use in ferrous materials to preserve cutting edge life, and wear proper personal protective equipment including eye protection when drilling.
