Hougen 12646 Annular Cutter 1-7/16 in Hss Tin

Product Description

The HOUGEN 12646 is a high speed steel annular cutter designed for clean, fast hole cutting in ferrous metals. Built from M2-grade high speed steel with a titanium nitride (TiN) coating, this cutter delivers extended tool life and reduced friction during cutting. It features a 1-7/16 inch cutting diameter and a 1 inch depth of cut, making it suitable for through-holes and stepped-hole applications in structural and fabrication work. The Weldon flat shank with two flats provides positive drive engagement and prevents slipping under load. Licensed trades and skilled fabricators use this cutter with magnetic drills and drill presses.

This annular cutter is suited for use on mild steel, stainless steel, and general steel stock in fabrication shops, ironworking, and structural steel installation. The 3/4 inch Weldon flat shank is a standard connection size compatible with most magnetic drill arbors used in the trade. It is commonly used in steel erection, HVAC duct framing, and mechanical pipe support fabrication where clean, burr-minimized holes are required without pilot drilling.

Installation Notes

Annular cutters of this type are installed and operated by machinists, ironworkers, and qualified fabricators. Secure the cutter firmly in the arbor by engaging all Weldon flat set screws before use. Always use cutting fluid rated for the workpiece material to reduce heat buildup and extend tool life. Ensure the workpiece is firmly clamped or the magnetic base is fully energized before beginning the cut.
