Hougen 12624 Annular Cutter 3/4 in Hss Tin Coated

Product Description

The HOUGEN 12624 is a high speed steel annular cutter designed for fast, clean through-hole cutting in metal. It cuts a ring of material rather than a solid slug, reducing cutting force and heat buildup compared to twist drills. The cutter measures 3/4 inch in diameter with a 1 inch depth of cut and is manufactured from M2-grade high speed steel with a titanium nitride (TiN) coating to extend tool life and reduce friction. It uses a 3/4 inch Weldon flat shank with two flats for secure chuck engagement. This tool is used by ironworkers, fabricators, maintenance technicians, and structural steel contractors.

This annular cutter is suited for drilling clean holes in mild steel, stainless steel, and general steel stock. The Weldon flat shank design is compatible with standard magnetic drill presses and annular cutter chucks that accept 3/4 inch Weldon-style tooling. It is a practical choice for structural steel fabrication, HVAC duct framing, equipment mounting, and general metalworking applications where precise, burr-minimized holes are required in plate or structural members.

Key Features

• 3/4 inch cutter diameter for standard structural hole sizes
• 1 inch depth of cut handles typical plate and structural stock thicknesses
• M2 high speed steel construction for durability in steel cutting applications
• Titanium nitride (TiN) coating reduces friction and extends cutting edge life
• 3/4 inch Weldon flat shank with 2 flats ensures positive, slip-resistant chuck engagement

Compatibility

Compatible with magnetic drill presses and annular cutter holders that accept a 3/4 inch Weldon flat shank. Rated for use in mild steel, stainless steel, and general steel materials.

Installation Notes

Installation and use of this cutter should be performed by a qualified metalworker or fabricator familiar with magnetic drill press operation. Before mounting or changing the cutter, ensure the drill press is fully powered down and the magnetic base is disengaged. Secure the shank firmly in the chuck so both Weldon flats are properly engaged to prevent slippage under load. Always use cutting fluid appropriate for the workpiece material to maintain cutter life and hole quality.
