Hertel 02387819 Reduced Shank Drill Bit 51/64 in Hss

Product Description

The HERTEL 02387819 is a reduced shank drill bit designed for drilling into low and medium tensile strength materials including mild steels, aluminum, plastics, and similar workpieces. The bit features a 51/64 inch (0.7969 inch decimal) cutting diameter with a 1/2 inch straight-cylindrical shank, allowing it to run in standard 1/2 inch drill chucks even though the cutting diameter exceeds that size. Constructed from high-speed steel with an oxide finish, the 02387819 delivers consistent performance in general-purpose metal and fabrication work. The 118-degree standard point angle suits a wide range of common materials and is compatible with standard drill press and hand-drill setups.

This bit is suited for production and maintenance applications where a full-shank bit of this diameter would require a larger chuck. The reduced shank design makes it practical for use on standard drill presses, magnetic drills, and handheld power drills equipped with 1/2 inch chucks. It is used in metal fabrication shops, maintenance facilities, and general machining environments. Right-hand spiral flutes with a regular spiral type evacuate chips effectively during through-hole and blind-hole drilling operations.

Key Features

• 51/64 inch cutting diameter (0.7969 inch decimal) with a 1/2 inch reduced straight-cylindrical shank
• 118-degree standard point angle for general-purpose drilling in low and medium tensile strength materials
• High-speed steel construction provides durability across common metal and non-metal workpieces
• Oxide finish helps reduce friction and provides light corrosion resistance during storage and use
• 3 inch flute length supports a maximum drilling depth of 3 inches
• Right-hand cut with regular spiral flutes for efficient chip evacuation

Compatibility

Designed for use in standard 1/2 inch drill chucks on drill presses, handheld power drills, and magnetic drills. Intended for drilling low and medium tensile strength materials.

Installation Notes

Installation should be performed by a qualified machinist or tool operator familiar with drill press and cutting tool safety procedures. Secure the shank fully in a 1/2 inch chuck and verify runout before drilling. Always clamp the workpiece securely and use appropriate personal protective equipment including eye protection. No coolant is specified for this bit; confirm suitability for your material and feed rate before extended use.
