Hertel 02387678 Reduced Shank Drill Bit 37/64 in Hss

Product Description

The HERTEL 02387678 is a reduced shank drill bit designed for drilling operations where a standard full-size shank would exceed the chuck capacity of the machine. Built from high-speed steel with an oxide finish, this bit measures 37/64 inch (0.5781 inch decimal) in cutting diameter with a 1/2 inch straight-cylindrical shank. The overall length is 6 inches with a 3 inch spiral flute length. The 118-degree standard point angle is a general-purpose geometry suited for a wide range of common materials. This bit is installed by machinists, maintenance technicians, and metalworking tradespeople in drill press, lathe, or hand-drill applications.

This bit is intended for use on low and medium tensile strength materials. Typical applications include drilling through mild steel, aluminum, brass, thermoplastics, and similar workpiece materials in production, maintenance, and repair environments. The reduced shank design allows the 37/64 inch diameter bit to seat in a standard 1/2 inch capacity chuck, expanding the usable range of the tool without requiring a larger chuck or machine spindle. Right-hand cutting direction is standard for conventional drill press and hand drill operation.

Key Features

• Reduced shank design: 37/64 inch cutting diameter fits a 1/2 inch chuck
• High-speed steel construction for durability across common metal and plastic workpieces
• 118-degree standard point angle for general-purpose drilling geometry
• Oxide finish provides mild corrosion resistance and surface hardness
• Right-hand spiral flute promotes chip evacuation during through-drilling
• 3 inch flute length supports drilling depth up to 3 inches

Compatibility

Designed for use in any drill press, CNC machine, or hand drill equipped with a 1/2 inch capacity chuck; suitable for low and medium tensile strength workpiece materials.

Installation Notes

This bit is installed by machinists or maintenance technicians using a standard 1/2 inch keyed or keyless chuck. Secure the shank fully into the chuck and verify runout before drilling. Use appropriate cutting fluid or dry-cutting practice per the workpiece material specification. Follow shop safety protocols and applicable OSHA machining guidelines when operating rotary cutting tools.
