Hougen 12319 Annular Cutter 0.748 in Hss Weldon Shank

Product Description

The HOUGEN 12319 is a high speed steel annular cutter designed for clean, fast hole cutting in ferrous metals. With a cutter diameter of 0.748 inches and a cutting depth of 25 millimeters (approximately 1 inch), it removes only a core of material rather than a full slug, reducing heat buildup and extending tool life compared to twist drills. The Weldon flat shank with two flats measures 3/4 inch in diameter and locks securely into compatible magnetic drill press chucks. The bright, uncoated finish is standard for general-purpose HSS cutters working in mild steel applications.

This cutter is intended for use in metal fabrication, structural steel work, maintenance and repair operations, and industrial trade applications where precise, burr-minimized holes are required. It is suited for use with magnetic base drills and compatible annular cutter holders in shop and field environments. Primary material application is mild steel and general steel stock. The 0.748-inch diameter is a standard sizing used across fabrication and ironworking trades.

Key Features

• 0.748-inch cutter diameter for precise hole sizing in steel
• High speed steel construction for durability in ferrous metal cutting
• Weldon flat shank with two flats provides positive chuck engagement and prevents slipping
• 3/4-inch shank diameter fits standard magnetic drill press chucks
• Bright, uncoated finish suitable for general-purpose mild steel applications
• Annular cutting action removes only a core plug, reducing heat and cycle time

Compatibility

Designed for use with magnetic base drills and annular cutter holders accepting a 3/4-inch Weldon flat shank. Rated for material application in mild steel and general steel stock.

Installation Notes

Annular cutters of this type are installed and serviced by machinists, fabricators, and ironworkers using magnetic base drill presses. Ensure the drill unit is fully secured to the workpiece and powered down before changing cutters. Use the appropriate arbor or chuck designed for 3/4-inch Weldon flat shanks and confirm the set screws engage both flats before operation. Always use cutting fluid or lubricant appropriate for HSS tooling in steel to maintain cutter life and cut quality.
