Hertel 2386324 Screw Machine Drill Bit Size 25 Hss

Product Description

The HERTEL 2386324 is a screw machine length drill bit designed for high-volume hole-making in metal fabrication, machining, and production drilling applications. Built from high-speed steel with an oxide coating, this bit carries a Size 25 wire gauge diameter of 0.1495 inches and an overall length of 2.0625 inches. The 135-degree split point reduces walking on entry and lowers thrust force, making it a reliable choice for drilling in steel, cast iron, and similar ferrous materials. The parallel web configuration and web-thinned geometry help maintain cutting efficiency throughout the flute length.

This bit is suited for use in CNC machining centers, drill presses, and hand-held electric drills in job shop and production environments. Its stub-length body — shorter than jobber-length bits — provides added rigidity in close-clearance setups and fixtures where overhang must be minimized. Machinists, tool-and-die tradespeople, and metalworking professionals who require consistent hole quality at small diameters will find this bit fits standard production workflows. The straight cylindrical shank seats directly into standard drill chucks without adapters.

Key Features

• Size 25 wire gauge diameter: 0.1495 inches for precision small-hole drilling
• 135-degree split point reduces thrust and self-centers on entry
• High-speed steel construction handles intermittent cutting in ferrous metals
• Oxide finish provides light corrosion resistance and reduces chip welding
• Screw machine (stub) length at 2.0625 inches overall adds rigidity over jobber-length alternatives
• Right-hand spiral flute with web-thinned, parallel web geometry for efficient chip evacuation

Compatibility

Designed as a standard screw machine length drill bit compatible with any drill press, CNC machining center, or hand drill equipped with a chuck accepting a 0.1495-inch straight cylindrical shank.

Installation Notes

Installation and bit changes should be performed with the machine fully powered down and the chuck key removed from the work area before securing the shank. A licensed machinist or qualified metalworking technician should verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before beginning a cut. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling deep holes or hard materials to extend tool life. Inspect the cutting edges and point geometry before each use and replace if chipping or wear is observed.
