Hougen 12320 Annular Cutter 0.7874 in Hss Weldon

Product Description

The HOUGEN 12320 is a high speed steel annular cutter designed for clean, precise hole cutting in ferrous metal workpieces. Unlike twist drills, annular cutters remove only a core ring of material, reducing the force required and extending tool life on repetitive drilling tasks. The cutter measures 0.7874 inches in diameter with a 0.984-inch (25 mm) cutting depth and mounts via a 0.75-inch Weldon flat shank with two flats for positive engagement in compatible magnetic drill presses. The bright, uncoated finish is standard for HSS cutters used in general fabrication where coating is not required.

This cutter is suited for metalworking professionals, ironworkers, structural steel fabricators, and maintenance tradespeople who use portable magnetic drill presses or drill press stations. It is appropriate for use on mild steel and general steel stock. The 0.7874-inch diameter is a common hole size requirement for conduit knockouts, bolt holes, and structural connections in both field and shop settings.

Key Features

• 0.7874-inch (20 mm) cutter diameter for precise, repeatable hole sizing
• 25 mm (0.984-inch) cutting depth handles typical plate and structural steel thickness
• High speed steel construction provides durability on mild steel and general steel applications
• 0.75-inch Weldon flat shank with 2 flats ensures secure, slip-free chuck engagement
• Bright, uncoated finish — standard HSS grade suitable for general-purpose cutting with cutting fluid

Compatibility

Designed as a replacement or additional cutter for magnetic drill presses and drill press arbors accepting a 0.75-inch Weldon flat shank. Rated for use on mild steel and steel workpieces.

Installation Notes

Installation is performed by metalworking or fabrication professionals using a magnetic drill press or compatible drill press with a Weldon shank arbor. Ensure the shank set screws engage both flats fully before drilling. Always apply cutting fluid during use to extend tool life and prevent heat buildup. Secure the workpiece or verify magnetic base engagement before beginning any cut.
