Hougen 12317 Annular Cutter 0.6693 in Hss Weldon

Product Description

The HOUGEN 12317 is a high speed steel annular cutter designed for clean, fast hole-cutting in mild steel and structural steel. Annular cutters remove only a core plug rather than the full disc of material, which reduces cutting force, extends tool life, and produces a precise, burr-minimal hole in a single pass. The 12317 measures 0.6693 inches in diameter and seats on a 3/4-inch Weldon flat shank with two flats for positive drive and no slippage under load. The bright, uncoated finish is standard for HSS cutters used in general fabrication work. Machinists, ironworkers, and metal fabricators are the primary users of this tool.

This cutter is suited for use on magnetic drill presses that accept a 3/4-inch Weldon shank, a common standard in portable and benchtop mag-drill applications. Typical applications include structural steel fabrication, steel erection, HVAC duct framing, and general metalworking where a clean through-hole is required in mild or low-carbon steel. The cutter is sold individually and is a direct-use item requiring no additional adapters when the host tool accepts a standard 3/4-inch Weldon connection.

Key Features

• 0.6693-inch (17 mm) cutting diameter for precise hole sizing in mild steel
• High speed steel construction provides durability across general fabrication tasks
• 3/4-inch Weldon flat shank with two flats for positive, slip-free drive
• 25 mm cutting depth suitable for typical structural steel plate and tube wall thickness
• Bright, uncoated finish — no coating to chip or peel during use
• Annular cutting geometry removes only the core plug, reducing heat and cutting force

Compatibility

Designed for use with magnetic drill presses and drill units fitted with a standard 3/4-inch Weldon shank chuck or arbor. Suitable for cutting mild steel and general carbon steel stock.

Installation Notes

Installation of annular cutters should be performed by qualified machinists or metalworkers familiar with mag-drill operation. Ensure the drill unit is powered off and unplugged before inserting or removing the cutter from the arbor. Tighten the Weldon shank set screw securely against both flats to prevent rotation under load. Use the appropriate cutting fluid or lubricant for the material being drilled to maintain cutter life and improve cut quality.
