Hertel C.E11.1032 Extra Length Drill Bit 0.4062 in Hss

Product Description

The HERTEL C.E11.1032 is an extra length drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. Built from high-speed steel (HSS) with an oxide finish, it offers solid wear resistance for general purpose metal drilling operations. The bit measures 0.4062 inches in diameter with a 118-degree point angle, providing a conventional split-point geometry suited to a wide range of ferrous and non-ferrous materials. With an overall length of 18 inches and a flute length of 12 inches, it is a go-to choice for machinists, maintenance technicians, and fabricators working on structural steel, pipe, or equipment components that require extended reach.

This bit is intended for use in drill presses, milling machines, and heavy-duty handheld or magnetic-base drills. It is well suited to maintenance and repair operations (MRO), industrial fabrication, and on-site metalwork where depth of cut exceeds the capacity of jobber-length tooling. The two-flute design promotes efficient chip evacuation over the full 12-inch flute length, reducing the risk of bit binding during deep passes. General purpose grade designation makes this bit appropriate for a broad range of shop and field drilling tasks.

Key Features

• Extra length design: 18-inch overall length with 12-inch flute for deep-hole reach
• High-speed steel construction provides heat and wear resistance during metal cutting
• Oxide finish reduces friction and provides basic surface protection
• 118-degree conventional point angle for general purpose metal drilling
• Two-flute geometry promotes chip evacuation in deep drilling applications
• 0.4062-inch diameter for precise sizing in standard and custom bore applications

Compatibility

Designed as a general purpose extra length drill bit compatible with standard drill chucks and drill presses accepting 0.4062-inch shank tooling in industrial and MRO applications.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal cutting practices. Secure the workpiece firmly before drilling and verify chuck runout is within acceptable limits before beginning a deep-hole operation. Reduce feed rate and apply appropriate cutting fluid when drilling ferrous materials to manage heat buildup over the extended flute length. Follow shop safety standards and applicable OSHA guidelines for rotating equipment.
