Hertel 89321459 Screw Machine Drill Bit 7/64 in Hss

Product Description

The HERTEL 89321459 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastics. It measures 7/64 inch (0.1094 inch decimal) in diameter with an overall length of 1-13/16 inches and a flute length of 13/16 inches. The shortened screw machine length body reduces deflection and improves rigidity in drill press, CNC, and turret lathe applications. The 118-degree split-point angle is a standard general-purpose geometry that starts on contact without a center punch on most materials. Manufactured from high-speed steel with a bright uncoated finish, this bit suits machinists, maintenance technicians, and fabricators who need a reliable everyday drill bit in the 0.1000 to 0.1500 inch size range.

The 89321459 is suited for production and maintenance drilling in light manufacturing, HVAC fabrication shops, plumbing rough-in work, and electrical panel shops where short, stiff drill bits are preferred in tight clearances or guided fixtures. The screw machine length format fits standard drill chucks and quick-change tooling holders commonly found on bench drill presses and handheld power tools. Right-hand cutting direction is the standard for conventional drill press rotation.

Key Features

• 7/64 inch diameter (0.1094 inch decimal) for precise small-diameter hole work
• 118-degree point angle for general-purpose cutting in a wide range of materials
• Screw machine length body at 1-13/16 inches OAL for added rigidity and reduced deflection
• High-speed steel construction provides toughness across ferrous and non-ferrous materials
• Bright uncoated finish for straightforward resharpening and visual wear inspection
• Right-hand cut compatible with standard drill press and power tool rotation

Compatibility

Designed as a general-purpose replacement or stock drill bit for applications requiring a 7/64 inch screw machine length bit in the 0.1000 to 0.1500 inch decimal size range.

Installation Notes

Install this bit into a standard drill chuck and tighten with a chuck key before operation. Secure the workpiece firmly before drilling to prevent spinning or movement. Use appropriate cutting fluid on harder metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace or resharpen if chipping or dulling is observed.
