Hertel 02387736 Reduced Shank Drill Bit 43/64 in Hss

Product Description

The HERTEL 02387736 is a reduced shank drill bit designed for drilling into low and medium tensile strength materials. The bit measures 43/64 inches (0.6719 inches) in diameter with a 1/2-inch straight-cylindrical shank, allowing it to seat in standard 1/2-inch chuck machinery without requiring a larger capacity tool. Constructed from high-speed steel (HSS) with an oxide finish, the 02387736 offers adequate wear resistance for general-purpose drilling in metalworking, fabrication, and maintenance applications. A 118-degree standard point angle suits a wide range of common drill press and hand drill operations. Licensed machinists, maintenance technicians, and metalworking tradespeople are the primary users of this bit.

This drill bit is suited for use in drill presses, milling machines, and hand-held power drills equipped with a 1/2-inch chuck. It is intended for right-hand cutting on low and medium tensile strength materials such as mild steel, aluminum, and similar metals. The 3-inch flute length provides a maximum drilling depth of 3 inches, making it appropriate for through-holes and moderate-depth blind bores in plate stock, structural members, and fabricated assemblies. The regular spiral flute geometry supports efficient chip evacuation during standard drilling operations.

Key Features

• 43/64-inch drill diameter (0.6719 inches decimal) with a reduced 1/2-inch straight-cylindrical shank
• 118-degree standard point angle for general-purpose entry into low and medium tensile strength materials
• High-speed steel construction with oxide finish for wear resistance in metalworking applications
• 3-inch flute length with regular spiral geometry for consistent chip evacuation
• Right-hand cutting direction compatible with standard drill press and power drill operation
• 6-inch overall length for reach in deeper setups without extended-length tooling

Compatibility

Designed as a general-purpose reduced shank drill bit for use in any 1/2-inch chuck drill press, mill, or hand-held power drill. Intended for drilling low and medium tensile strength materials.

Installation Notes

Secure the 1/2-inch shank firmly in a properly sized chuck before operation and verify runout is within acceptable limits for the application. Power down and de-energize any machine tool completely before changing or seating the bit. Follow applicable shop safety standards and machine tool manufacturer guidelines for speed and feed selection based on workpiece material. Do not force the bit through hardened or high-tensile materials beyond its rated workpiece material range.
