Hertel 02387785 Reduced Shank Drill Bit 3/4 in Hss

Product Description

The HERTEL 02387785 is a reduced shank twist drill bit designed for drilling into low and medium tensile strength materials using standard drill presses, lathes, and hand-held power tools with 1/2 inch chuck capacity. The bit features a 3/4 inch cutting diameter with a reduced 1/2 inch straight-cylindrical shank, allowing it to fit into smaller chucks without sacrificing hole size. The 118-degree standard point angle suits general-purpose drilling in mild steel, aluminum, brass, and similar workpiece materials. An oxide finish provides light corrosion resistance during storage and use. Overall length is 6 inches with a 3 inch spiral flute length, and the right-hand cutting direction is standard for conventional drill operation.

This drill bit is suited for metalworking shops, maintenance and repair operations, and light fabrication environments. It is appropriate for use in residential or commercial trade settings where a journeyman machinist, millwright, or maintenance technician requires a general-purpose drill bit capable of producing 3/4 inch holes without a larger chuck. The reduced shank design makes it practical for portable drilling applications where only a 1/2 inch drill is available on site.

Key Features

• Reduced 1/2 inch shank fits standard 1/2 inch drill chucks while producing a 3/4 inch hole
• 118-degree standard point angle for general-purpose drilling in low and medium tensile strength materials
• High-speed steel construction provides good wear resistance for intermittent drilling operations
• Oxide finish offers light corrosion protection during storage
• 3 inch spiral flute length supports chip evacuation up to 3 inches of drilling depth
• Right-hand cut, regular spiral flute — compatible with standard drill rotation

Compatibility

Designed as a general-purpose reduced shank drill bit for use in 1/2 inch capacity drill chucks on drill presses, lathes, and portable power drills. Suitable for low and medium tensile strength workpiece materials.

Installation Notes

Installation of this drill bit is performed by a machinist, millwright, or qualified maintenance technician. Secure the reduced shank fully within the chuck jaws and verify tightness before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable workplace safety standards and equipment manufacturer guidelines for speed selection based on material and bit diameter.
