Hertel 71205603 Jobber Length Drill Bit 1/64 in Hss

Product Description

The HERTEL 71205603 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and similar materials. Manufactured from high speed steel with an oxide coating for added surface protection, it features a 118-degree standard point angle and a right-hand spiral flute configuration. The bit measures 1/64 inch (0.0156 inch decimal) in diameter with a 3/4-inch overall length and a 3/16-inch flute length. The two-flute, regular spiral design promotes consistent chip evacuation during drilling. This bit is commonly installed and used by machinists, HVAC technicians, plumbers, and electricians requiring precision in small-diameter pilot or clearance holes.

This drill bit is suited for light-duty and precision drilling applications where small-diameter holes are required. Its straight-cylindrical shank makes it compatible with standard drill chucks across a wide range of corded and cordless tools. The general-purpose grade and web-thinned, tapered web construction help reduce thrust during entry, making it appropriate for use in sheet metal, thin-gauge steel, plastic, and similar substrates encountered in trade service work.

Key Features

• 1/64 inch (0.0156 inch) diameter for precision small-diameter drilling
• High speed steel construction for durability across general-purpose applications
• Oxide coating provides surface protection and reduced friction
• 118-degree standard point angle for reliable entry on flat and curved surfaces
• Right-hand, two-flute regular spiral for consistent chip clearance
• Web-thinned tapered web reduces drilling thrust and entry resistance
• Straight-cylindrical shank fits standard drill chucks without modification

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks on corded and cordless drilling equipment. No coolant-through capability; intended for dry or externally lubricated drilling only.

Installation Notes

Installation and use should be performed by qualified tradespeople following applicable safety guidelines for rotating cutting tools. Secure the workpiece before drilling and verify chuck tightness before operation. At this diameter, bit breakage risk increases with excessive lateral pressure or misalignment — maintain steady, centered feed pressure. Wear appropriate eye protection at all times when operating drilling equipment.
