Hougen 3-12258 Annular Cutter 1-13/16 in Hss Weldon

Product Description

The HOUGEN 3-12258 is a high speed steel annular cutter designed for clean, full-diameter hole cutting in mild steel and steel plate. With a cutting diameter of 1-13/16 inches (1.8125 inches decimal) and a 3-inch depth of cut, this cutter handles deep-reach applications where twist drills fall short. The 3/4-inch Weldon flat shank with two flats provides positive drive engagement in compatible magnetic drill presses and annular cutter arbors. The bright, uncoated finish is standard for HSS cutters used in general fabrication and structural steel work. Machinists, ironworkers, pipefitters, and steel fabricators are the primary users of this tool class.

This annular cutter is suited for structural steel fabrication, ironwork, and mechanical installations where accurately sized holes are required through plate, beam flange, or tube wall material. The 3-inch depth of cut makes it effective on thick structural members or stacked material where a standard short-reach cutter would bottom out before completing the hole. It is designed for use in portable magnetic drill presses that accept a 3/4-inch Weldon shank, a common setup on job sites and in fabrication shops.

Key Features

• 1-13/16 inch (1.8125 inch) cutting diameter for precise, full-diameter holes
• 3-inch depth of cut for deep-reach drilling through thick or stacked steel
• High speed steel construction for durability in ferrous metal applications
• 3/4-inch Weldon flat shank with 2 flats for positive rotational drive and secure chuck engagement
• Bright/uncoated finish, standard for HSS annular cutters in general steel fabrication
• Compatible material applications include mild steel and steel plate

Compatibility

Designed for use in magnetic drill presses and arbors that accept a 3/4-inch Weldon flat shank. Intended material applications are mild steel and steel as specified by the manufacturer.

Installation Notes

Installation and use of annular cutters should be performed by qualified machinists, ironworkers, or fabricators familiar with magnetic drill press operation. Secure the Weldon shank fully into the chuck or arbor and confirm the set screw engages a flat before starting the drill. Always use cutting fluid appropriate for ferrous metals to extend cutter life and maintain cut quality. Inspect the cutter for chipped or worn teeth before each use and never exceed the drill press manufacturer's recommended RPM for the cutter diameter.
