Hertel 89320873 Screw Machine Drill Bit Wire 34 Hss

Product Description

The HERTEL 89320873 is a screw machine length drill bit sized to wire gauge 34, equivalent to 0.1110 inches in diameter. Designed for general-purpose metal drilling, this bit features a 118-degree split-free point and is manufactured from high-speed steel with a bright, uncoated finish. The shortened flute and body length of a screw machine style bit provides added rigidity over a standard jobber-length bit, making it well suited for production drilling, CNC machining, and drill press work where chatter and deflection need to be minimized. The right-hand cutting direction follows standard convention for most drill presses, lathes, and hand drills.

This drill bit is used in metalworking applications requiring small-diameter precision holes. Wire gauge sizing makes it common in electronics assembly, toolmaking, tap drilling, and light sheet metal work. The overall length of 1.875 inches and flute length of 0.875 inches suit it to close-clearance setups and short-stroke drilling operations. It is typically installed by machinists, tool and die makers, and HVAC or electrical tradespeople drilling through sheet metal or enclosures.

Key Features

• Wire gauge 34 diameter equals 0.1110 inches for consistent sizing
• 118-degree point angle provides a self-centering start on most metals
• High-speed steel construction handles general-purpose drilling at standard speeds
• Bright, uncoated finish allows visual wear inspection during use
• Screw machine length body adds rigidity and reduces deflection in short-stroke applications
• Right-hand cut matches standard drill chuck and machine spindle rotation

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard 3-jaw drill chucks and collet systems accepting round-shank bits at or near 0.1110 inches diameter.

Installation Notes

This bit is installed and changed by machinists or tradespeople using standard drill chuck keys or keyless chucks. Always power down and de-energize the drill press, lathe, or hand drill before changing bits. Secure the bit fully in the chuck to the full depth of the shank before operation. Use cutting fluid appropriate to the workpiece material to extend bit life and maintain hole quality.
