Hougen 12331 Annular Cutter 1.2205 in Hss Weldon Shank

Product Description

The HOUGEN 12331 is a high speed steel annular cutter designed for cleanly cutting through mild steel and general steel stock. With a 1.2205-inch cutter diameter and a 3/4-inch Weldon flat shank with two flats, this cutter seats securely in compatible magnetic drill presses and milling setups. The bright, uncoated finish maintains consistent cutting performance across standard ferrous materials. At 0.3 pounds, it is a lightweight tool that delivers precise, slug-ejecting cuts rather than full-disk removal, reducing heat buildup and extending tool life on production runs and field work alike. Fabricators and ironworkers commonly reach for this cutter on structural and sheet steel applications.

This annular cutter is suited for use in magnetic drill press applications on mild steel and general steel plate. A 25-millimeter cutting depth supports through-cuts on typical structural members and plate stock. The Weldon flat shank design is the standard connection type found on most magnetic drill presses used in steel fabrication, construction, and maintenance environments. It is installed by licensed fabricators, ironworkers, and maintenance technicians who require accurate, burr-minimized holes without the full-material removal of a twist drill.

Key Features

• 1.2205-inch cutter diameter for standard hole sizing in steel fabrication work
• High speed steel construction provides durability on mild steel and steel stock
• 3/4-inch Weldon flat shank with two flats for secure chuck engagement
• 25-millimeter cutting depth suits common structural plate and member thicknesses
• Bright, uncoated finish delivers reliable performance without coating maintenance concerns
• Lightweight at 0.3 pounds for easy handling in both shop and field settings

Compatibility

Designed for use on mild steel and steel materials. Compatible with magnetic drill presses and milling setups that accept a 3/4-inch Weldon flat shank connection.

Installation Notes

This cutter is installed by fabricators and ironworkers using magnetic drill presses equipped with a Weldon-style chuck. Ensure the drill press is powered down and the magnet is disengaged before changing cutters. Seat the shank fully and tighten the set screws against the Weldon flats before operation. Always use the appropriate cutting fluid for the material to reduce heat and extend cutter life.
