Hertel 02387660 Reduced Shank Drill Bit 9/16 in Hss

Product Description

The HERTEL 02387660 is a reduced shank twist drill bit designed for drilling operations in low and medium tensile strength materials. The bit features a 9/16 inch cutting diameter with a 1/2 inch straight-cylindrical shank, allowing it to chuck into standard 1/2 inch capacity drill chucks even though the cutting diameter is larger. Constructed from high-speed steel with an oxide finish, it delivers reliable performance across common shop and field drilling tasks. The 118-degree standard point angle is a general-purpose geometry suited for a wide range of ferrous and non-ferrous workpiece materials.

This drill bit is intended for use in stationary drill presses, magnetic base drills, and hand-held power drills equipped with a 1/2 inch chuck. It is well suited for mechanical, HVAC, plumbing, and electrical tradespeople who need to drill holes slightly larger than what their chuck capacity would ordinarily allow. The 3 inch flute length supports a maximum drilling depth of 3 inches, making it practical for structural steel, angle iron, sheet metal stacks, and similar materials encountered in trade work.

Key Features

• Reduced shank design: 9/16 inch cut diameter fits into a standard 1/2 inch chuck
• High-speed steel construction for durability in low and medium tensile strength materials
• 118-degree standard point angle for general-purpose drilling geometry
• Right-hand spiral flute with regular helix for efficient chip evacuation
• Oxide finish provides mild corrosion resistance and reduces friction during cutting
• 6 inch overall length with 3 inch flute length for controlled depth drilling

Compatibility

Designed as an OEM-style replacement or direct-use reduced shank drill bit for any 1/2 inch drill chuck application requiring a 9/16 inch bore diameter in low to medium tensile strength materials.

Installation Notes

Secure the shank fully into the drill chuck before operation and verify chuck key is removed prior to powering on the drill. When drilling metal, use cutting fluid or oil where recommended by the material supplier to extend tool life and reduce heat buildup. Wear appropriate PPE including eye protection and secure the workpiece before drilling. Inspect the cutting edges for wear before each use and replace the bit if the point shows chipping or significant dulling.
