Hougen 3-12250 Annular Cutter 1-9/16 in Hss Weldon

Product Description

The HOUGEN 3-12250 is a high speed steel annular cutter designed for clean, precise hole cutting in mild steel and steel stock. With a cutter diameter of 1-9/16 inches (1.5625 inches decimal) and a cutting depth of 3 inches, this tool handles deep-hole applications where twist drills fall short. The Weldon flat shank with two flats and a 3/4-inch shank diameter provides a secure, slip-resistant connection in compatible magnetic drill presses and annular cutter holders. The bright, uncoated finish is standard for general-purpose HSS cutters. It is installed by fabricators, ironworkers, pipefitters, and structural steel mechanics.

This annular cutter is suited for structural fabrication, pipe fitting, and steel plate work where large-diameter, deep-cut holes are required. It performs best in stationary or portable magnetic drill press setups. The 3-inch depth of cut makes it appropriate for through-cuts in thick-section steel members, gussets, and heavy-wall material. Applications include beam drilling, angle iron work, and on-site structural steel fabrication.

Key Features

• 1-9/16 inch cutter diameter (1.5625 inches decimal) for large-bore hole production
• 3-inch depth of cut for deep through-hole applications in thick steel
• High speed steel construction for durability in ferrous metal cutting
• Weldon flat shank with two flats and 3/4-inch shank diameter for positive drive retention
• Bright, uncoated finish — standard general-purpose HSS configuration
• Designed for use with magnetic drill presses and compatible annular cutter arbors

Compatibility

Designed for use in magnetic drill presses and annular cutter holders that accept a 3/4-inch Weldon flat shank. Rated for material applications in mild steel and steel.

Installation Notes

Install in a compatible magnetic drill press or milling machine chuck rated for the 3/4-inch Weldon shank diameter. Secure set screws firmly against the Weldon flats before operating to prevent shank slippage under torque. Always use cutting oil or lubricant appropriate for HSS tooling in steel to extend cutter life and maintain hole quality. Disconnect or de-energize the drill unit and allow the cutter to come to a complete stop before changing tooling.
