Hertel 89320774 Screw Machine Drill Bit 3/32 in Hss

Product Description

The HERTEL 89320774 is a screw machine length drill bit designed for general-purpose drilling in metal, plastic, and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable performance across a wide range of shop and field applications. The 118-degree split-point angle provides consistent centering and clean entry without a pilot hole. At 1.75 inches overall length, this stub-length format offers added rigidity compared to jobber-length bits, reducing deflection when drilling in tight spaces or short-reach setups. Licensed trades and machine operators rely on this format for production drilling and maintenance work alike.

This bit is suited for use in drill presses, CNC machines, hand drills, and screw machine operations where a compact, rigid cutting tool is required. The 3/32-inch diameter and 0.75-inch flute length make it well matched for light-duty metal fabrication, HVAC bracket work, electrical panel knockouts, and general maintenance drilling. The right-hand cut is compatible with standard chuck tooling across all common drill platforms.

Key Features

• High-speed steel construction for durability across general-purpose drilling tasks
• 118-degree point angle for self-centering entry without a separate pilot hole
• Bright uncoated finish suitable for a wide range of base materials
• Screw machine (stub) length reduces deflection in short-reach applications
• Right-hand cut compatible with standard drill chucks and screw machine tooling
• 3/4-inch flute length provides adequate chip clearance at this diameter

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard 3-jaw chucks and collet holders accepting 3/32-inch shank tooling across drill presses, hand drills, and CNC drilling platforms.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Always ensure the drill chuck is fully tightened and the workpiece is secured before beginning any drilling operation. Eye protection and appropriate chip guarding are required per standard shop safety practices. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
