Hertel 89320584 Screw Machine Drill Bit Size 26 Hss

Product Description

The HERTEL 89320584 is a screw machine length drill bit sized to wire gauge 26, equal to 0.1470 inches in decimal. Built from high-speed steel with a bright, uncoated finish, it runs a standard 118-degree split-style point suited for general-purpose drilling in a wide range of materials. The shorter screw machine length body — 2-1/16 inches overall — provides added rigidity compared to jobber-length bits, making it a common choice in machine shops, production environments, and field service work where chatter and deflection need to be minimized. Right-hand cut. Typically installed in drill presses, CNC machines, or hand drills by machinists, maintenance technicians, and trade professionals.

This bit fits general-purpose drilling applications across metal fabrication, HVAC equipment assembly, plumbing rough-in, and electrical panel work where small-diameter precision holes are required. The 1-inch flute length accommodates shallow-to-moderate depth holes typical of sheet metal, light steel, aluminum, brass, and similar workpiece materials. Its compact overall length makes it especially practical in tight-clearance drilling situations where a standard jobber-length bit would be too long to seat properly in a chuck or to maneuver safely.

Key Features

• Wire gauge size 26, equivalent to 0.1470 inches decimal diameter
• 118-degree drill point angle for general-purpose material entry
• High-speed steel construction for durability across common metals
• Screw machine length body at 2-1/16 inches OAL for increased rigidity
• 1-inch flute length for shallow to moderate depth drilling
• Right-hand cut with bright, uncoated finish — no coating to chip or flake

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard three-jaw drill chucks and collet systems accepting a 0.1470-inch shank diameter in drill presses, CNC drilling centers, and portable hand drills.

Installation Notes

Secure the workpiece firmly before drilling to prevent movement at small diameters. Ensure the drill chuck is fully tightened and the bit is seated straight to avoid runout and premature tip wear. Apply appropriate cutting fluid for ferrous metals to extend tool life and improve hole quality. Inspect the drill point before each use — a chipped or worn 118-degree tip at this diameter will wander and produce an oversized hole.
