Hougen 12217 Annular Cutter 17/32 in Hss Weldon Shank

Product Description

The HOUGEN 12217 is a high speed steel annular cutter designed for clean, fast hole cutting in mild steel and steel plate. With a 17/32-inch cutting diameter and a 2-inch depth of cut, this cutter removes only a thin ring of material rather than a full slug, reducing heat buildup and extending tool life compared to twist drills. The 3/4-inch Weldon flat shank with two flats provides positive drive engagement and prevents slippage in compatible magnetic drill press chucks. The bright, uncoated finish is standard for HSS annular cutters used in general fabrication and structural steel work.

This cutter is suited for use in magnetic drill presses and drill press applications found in steel fabrication shops, structural ironwork, HVAC duct framing, and general metal construction. The 17/32-inch diameter is a common size for bolt clearance and fastener pass-through holes in mild steel. The 2-inch depth of cut accommodates standard structural steel sections and plate stock. Licensed tradespeople and fabricators working with magnetic base drills will find this a direct fit for Weldon-style spindle chucks requiring a 3/4-inch shank.

Key Features

• 17/32-inch cutting diameter produces precise, consistent holes in mild steel and steel
• 2-inch depth of cut handles standard structural steel sections and plate
• High speed steel construction provides durability in ferrous metal cutting applications
• 3/4-inch Weldon flat shank with 2 flats ensures positive chuck engagement and prevents rotation
• Bright, uncoated finish — no additional coating to chip or flake during use
• Annular cutting geometry removes only a ring of material, reducing feed force and heat

Compatibility

Designed for use in magnetic drill presses and drill presses equipped with a Weldon-style chuck accepting a 3/4-inch shank diameter. Suitable for cutting mild steel and steel stock.

Installation Notes

Annular cutters of this type are installed and removed by a licensed or qualified operator following standard machine shop or fabrication safety practices. Ensure the drill press or magnetic base drill is fully powered off and locked out before changing cutters. Secure the Weldon shank fully into the chuck and tighten all set screws against the flats before operation. Use cutting fluid appropriate for HSS tooling on steel to extend cutter life and manage heat.
