Hertel 02388015 Reduced Shank Drill Bit 1-7/64 in Hss

Product Description

The HERTEL 02388015 is a reduced shank twist drill bit designed for drilling through low and medium tensile strength materials in metalworking and general fabrication applications. The bit measures 1-7/64 inches (1.1094 inches decimal) in cutting diameter and features a 1/2 inch straight-cylindrical shank, allowing it to seat in standard half-inch chucks even though the cutting diameter is larger. Overall length is 6 inches with a 3 inch spiral flute length. The 118-degree standard point angle suits a wide range of common shop and field drilling tasks. An oxide finish provides baseline surface protection. Machinists, tool-and-die workers, and maintenance mechanics are the primary installers.

This bit is suited for production drilling and maintenance work on low and medium tensile strength materials such as mild steel, aluminum, and similar alloys. The reduced shank design makes it practical for use in drill presses or hand drills equipped with 1/2 inch chucks where a full-diameter shank would not fit. The right-hand spiral flute configuration clears chips efficiently during through-hole and blind-hole drilling operations. It is sold individually and is appropriate for both shop-bench use and field service environments.

Key Features

• 1-7/64 inch cutting diameter (1.1094 inches decimal) with a reduced 1/2 inch straight-cylindrical shank for compatibility with standard chucks
• 118-degree standard point angle for general-purpose drilling in low and medium tensile strength materials
• High-speed steel (HSS) construction for durability across repeated use
• Oxide finish for baseline corrosion and wear resistance
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• 6 inch overall length with 3 inch maximum drilling depth

Compatibility

Designed for use in drill presses and hand drills with 1/2 inch chucks; rated for drilling low and medium tensile strength materials including mild steel and aluminum alloys.

Installation Notes

Secure the shank fully in a properly tightened chuck before operation. Always power down and de-energize the drill press or tool before changing bits. Use appropriate work-holding to prevent workpiece movement during drilling. Eye protection and chip guards should be used in accordance with applicable shop safety standards.
