Hougen 12154 Annular Cutter 1-11/16 in Hss Weldon

Product Description

The HOUGEN 12154 is a high speed steel annular cutter designed for clean, fast through-holes in mild steel and general steel stock. Unlike twist drills, annular cutters remove only a core of material at the perimeter of the hole, reducing the force required and leaving a precise, burr-minimal bore. The 12154 cuts to a diameter of 1-11/16 inches and reaches a cutting depth of 1 inch. The Weldon flat shank, with two flats and a 3/4-inch shank diameter, seats securely in compatible magnetic drill press arbors. The bright, uncoated HSS finish suits standard ferrous cutting applications where specialty coatings are not required. Installed by machinists and ironworkers in fabrication and structural steel work.

The HOUGEN 12154 is suited for drilling operations in mild steel and structural steel using magnetic base drills, drill presses, or milling machines equipped with a 3/4-inch Weldon-style arbor. Typical applications include fabrication shops, steel erection, and on-site structural work where precise, large-diameter holes are needed without pilot drilling. The uncoated HSS construction is appropriate for lower-speed, cutting-fluid-assisted operations on ferrous materials.

Key Features

• 1-11/16 inch cutter diameter for large-bore applications in steel
• 1 inch cutting depth accommodates standard structural stock thicknesses
• High speed steel construction provides durability in ferrous metal cutting
• Weldon flat shank with two flats resists slipping in the arbor under load
• 3/4-inch shank diameter fits standard magnetic drill and milling arbors
• Bright, uncoated finish compatible with cutting fluid use on mild and general steel

Compatibility

Designed for use with magnetic drill presses and milling machine arbors accepting a 3/4-inch Weldon flat shank. Rated for material application in mild steel and general steel stock.

Installation Notes

Installation and operation should be performed by qualified machinists or ironworkers familiar with rotary cutting tools. Secure the magnetic drill base fully before engaging the cutter, and confirm the arbor set screw engages both Weldon flats before operation. Apply cutting fluid continuously during use to extend tool life and improve cut quality. Disconnect power to the drill before changing or inspecting the cutter.
