Hertel 71206858 Jobber Drill Bit Wire 68 Hss Oxide

Product Description

The HERTEL 71206858 is a jobber-length drill bit sized to wire gauge 68, equivalent to 0.0310 inches in decimal. Constructed from high speed steel with an oxide coating, this bit is designed for general-purpose drilling in metal, plastic, and similar materials where precision small-diameter holes are required. The standard 118-degree point angle and two-flute spiral configuration promote clean chip evacuation and accurate hole entry. At 1.375 inches overall length with a 0.5-inch flute length, this bit fits standard drill chucks and rotary tools used in bench and hand-drill applications. It is suited for use by machinists, electricians, HVAC technicians, and plumbers who need reliable small-gauge drilling in tight or confined spaces.

This bit is well suited for light-duty production drilling, maintenance and repair work, and precision layout drilling across residential and commercial service applications. The straight-cylindrical shank and regular spiral type make it compatible with standard three-jaw chucks. The web-thinned, tapered web configuration reduces thrust required during entry, which is beneficial when working in thin-gauge sheet metal or circuit board stock. Individual packaging makes this bit easy to stock and reorder as part of a standard shop consumables inventory.

Key Features

• Wire size 68 with 0.0310-inch decimal diameter for precision small-hole applications
• High speed steel construction with oxide coating for improved wear resistance
• Standard 118-degree point angle for general-purpose use across common materials
• Two-flute spiral design promotes chip clearance and reduces heat buildup
• Web-thinned tapered web reduces drilling thrust on entry
• Straight-cylindrical shank fits standard drill chucks and rotary tool collets

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw chucks and rotary tools accepting a 0.0310-inch straight-cylindrical shank.

Installation Notes

This bit is installed and used by machinists, HVAC technicians, electricians, and plumbers during fabrication and service work. Secure the shank fully in the chuck before operation and verify chuck is tightened to prevent slippage. Use appropriate drilling speed for the material being worked — higher RPM is generally recommended for small-diameter bits in metal. Inspect the bit for chipping or wear before each use, as small-gauge bits are susceptible to breakage under lateral load.
