Hertel 02387751 Reduced Shank Drill Bit 45/64 Inch Hss

Product Description

The HERTEL 02387751 is a reduced shank drill bit designed for drilling into low and medium tensile strength materials. The bit carries a 45/64-inch cutting diameter (0.7031 inches decimal) on a 1/2-inch straight-cylindrical shank, making it compatible with standard 1/2-inch drill chucks without requiring a larger spindle bore. The 118-degree standard point angle provides a reliable, self-starting entry geometry suited to general-purpose production and maintenance drilling. The body is high-speed steel with an oxide finish that provides light corrosion resistance and reduces friction during cutting. Overall length is 6 inches with a 3-inch flute length. The bit cuts right-hand with a regular spiral flute pattern and requires no coolant for typical applications.

This drill bit suits maintenance, fabrication, and general shop applications where a reduced shank allows use of a common 1/2-inch chuck while still producing a hole near the 3/4-inch range. Typical installations include structural steel layout, plate work, and general metalworking on mild steel, aluminum, and similar low to medium tensile strength workpiece materials. It is sized for use in bench drill presses, floor-standing drill presses, and hand-held corded drill drivers with 1/2-inch chuck capacity.

Key Features

• 45/64-inch cutting diameter (0.7031 inches) on a reduced 1/2-inch straight-cylindrical shank
• 118-degree standard point angle for reliable entry on low and medium tensile strength materials
• High-speed steel construction for durability across general metalworking tasks
• Oxide finish reduces surface friction and provides light corrosion resistance
• Regular spiral flute with 3-inch flute length supports chip evacuation up to 3 inches drilling depth
• Right-hand cut, no coolant required for typical use

Compatibility

Designed as a general-purpose reduced shank drill bit for use in any 1/2-inch chuck-capacity drill press or hand drill; suited to low and medium tensile strength workpiece materials including mild steel and aluminum.

Installation Notes

Installation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotating cutting tools. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the shank before operation. Always wear appropriate eye protection and follow applicable shop safety procedures when operating drill presses or hand drills. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or excessive dullness is observed.
