Hertel 2385763 Screw Machine Drill Bit 1/16 in Hss

Product Description

The HERTEL 2385763 is a screw machine length drill bit engineered for high-speed steel cutting in tight-clearance applications. It measures 1/16 inch in diameter with an overall length of 1-5/8 inches and a flute length of 5/8 inch, making it well suited for work in confined spaces where standard-length bits cannot maneuver. The 135-degree split point starts on contact without walking, reducing the need for a center punch. An oxide finish provides added lubricity and mild corrosion resistance. This is a right-hand, spiral-flute bit with a straight cylindrical shank and web-thinned, parallel web configuration. Machinists, tool-and-die workers, and trade professionals in metal fabrication handle this type of bit regularly.

This screw machine drill bit is intended for drilling small-diameter holes in metal and similar materials where a shorter, more rigid bit reduces deflection and chatter. The stubby geometry improves rigidity compared to jobber-length bits, which is useful when drilling on lathes, drill presses, or CNC equipment. Its heavy-duty grade designation indicates suitability for demanding production environments. The 1/16 inch diameter fits small fastener pilot holes, precision metal work, and general fabrication tasks where tight dimensional tolerances are required.

Key Features

• 135-degree split point starts on contact, minimizing bit walking without a center punch
• Screw machine length body at 1-5/8 inches OAL increases rigidity and reduces deflection in close-quarters drilling
• High-speed steel construction withstands heat generated during metal drilling
• Oxide coating adds lubricity and light corrosion resistance
• Web-thinned parallel web lowers thrust force required during drilling
• Straight cylindrical shank is compatible with standard drill chucks

Compatibility

Designed as an OEM-style replacement or standard supply item for screw machine length drill bit applications requiring a 1/16 inch diameter, straight cylindrical shank, and right-hand cutting direction.

Installation Notes

This bit is installed and operated by machinists and trade professionals using drill presses, lathes, or CNC equipment. Secure the straight cylindrical shank firmly in the chuck before operation to prevent slipping. Always power down and de-energize the machine before changing bits. Use appropriate cutting fluid for the material being drilled to extend bit life and maintain hole quality.
