Hougen 12744 Annular Cutter 1-3/8 in Hss Tin

Product Description

The HOUGEN 12744 is a high-speed steel (HSS) annular cutter designed for clean, efficient hole cutting in ferrous metals. It features a 1-3/8 inch cutting diameter and a 2 inch depth of cut, making it well suited for thicker structural steel applications. The cutter is manufactured from M2-grade high-speed steel and carries a titanium nitride (TiN) finish that increases surface hardness and extends cutting life compared to uncoated tooling. The 3/4 inch Weldon flat shank with two flats provides positive drive and eliminates slippage in compatible magnetic drill press chucks. Machinists, ironworkers, and structural fabricators are the primary users of this tool.

The HOUGEN 12744 is intended for use in magnetic drill presses and milling machines equipped with a Weldon-style chuck accepting a 3/4 inch shank. It is rated for cutting mild steel, stainless steel, and general steel stock. The 2 inch depth of cut allows the cutter to pass through standard structural members, pipe flanges, and plate steel in a single pass without repositioning. It is commonly used in fabrication shops, ironworking, and on-site structural steel erection where portable mag drills are the standard tool of choice.

Key Features

Compatibility

Designed for use with magnetic drill presses and milling machines equipped with a Weldon-style chuck accepting a 3/4 inch shank diameter. Suitable for cutting mild steel, stainless steel, and steel stock as noted in the manufacturer specifications.

Installation Notes

Annular cutters should be installed and operated by qualified machinists or ironworkers familiar with magnetic drill press operation. Ensure the magnetic drill base is fully seated and energized on a clean, flat steel surface before starting the cut. Always use an appropriate cutting fluid or pilot pin lubricant to extend cutter life and prevent heat buildup. Inspect the Weldon flat shank set screws in the chuck for proper tightening before each use to prevent shank movement during the cut.
