Hougen 12740 Annular Cutter 1-1/4 in 2 in Hss Tin

Product Description

The HOUGEN 12740 is a high speed steel annular cutter designed for clean, fast through-holes in ferrous materials. It cuts a 1-1/4 inch diameter hole to a depth of 2 inches, removing only the material at the hole perimeter rather than boring out the full slug. The cutter is made from M2 grade high speed steel and finished with a Titanium Nitride (TiN) coating that reduces friction, extends edge life, and helps resist heat buildup during prolonged cuts. The Weldon Flat shank with two flats provides a secure, non-slip connection to magnetic drill presses and compatible rotary broaching setups.

The 12740 is suited for structural steel fabrication, ironworking, and general metalworking applications where clean hole tolerances matter. It is appropriate for use on mild steel, stainless steel, and carbon steel workpieces. The 3/4 inch Weldon shank is the standard interface for magnetic base drills used in field ironworking, steel erection, and shop fabrication environments. Licensed contractors and fabricators in HVAC ductwork, mechanical piping, and structural steel trades commonly use cutters in this size range for pipe penetrations, flange prep, and bracket mounting holes.

Key Features

• 1-1/4 inch cutting diameter with 2 inch depth of cut for through-holes in structural steel
• M2 high speed steel construction for durability and edge retention across ferrous materials
• Titanium Nitride (TiN) coating reduces heat and friction, extending tool life
• 3/4 inch Weldon Flat shank with two flats for secure, slip-resistant chuck engagement
• Rated for mild steel, stainless steel, and carbon steel material applications

Compatibility

Designed for use with magnetic drill presses and rotary broach setups that accept a 3/4 inch Weldon Flat shank. Compatible with mild steel, stainless steel, and general carbon steel workpieces.

Installation Notes

Installation requires a magnetic drill press or compatible drill unit with a 3/4 inch Weldon Flat chuck or arbor. Secure the cutter firmly using the Weldon Flat flats before powering the drill. Use appropriate cutting fluid or lubricant on the workpiece to manage heat and prolong cutting edge life. Always clamp or magnetically secure the workpiece per standard metalworking practice before initiating the cut.
