Hougen 4-18248 Annular Cutter 1-1/2 in Carbide Tipped

Product Description

The HOUGEN 4-18248 is a carbide-tipped annular cutter designed for drilling clean, full-diameter holes through metal without the need for pilot drilling or step drilling. It features a 1-1/2 inch cutting diameter and a 4 inch depth of cut, making it suitable for deep-reach applications in structural steel fabrication, ironwork, and heavy mechanical assembly. The 3/4 inch shank diameter with 2 flats provides a secure, positive lock in compatible mag-drill chucks. The oxide straw finish helps resist heat buildup during prolonged cuts. Typically installed and operated by ironworkers, structural fabricators, and maintenance machinists.

This annular cutter is rated for use on aluminum, mild steel, stainless steel, and general steel stock. The 4 inch depth of cut makes it well suited for thick structural members, I-beams, angle iron, and plate steel where standard twist drills fall short. It is used with magnetic drill presses and is common on job sites, fabrication shops, and maintenance facilities where repeated precise hole-cutting in metal is required.

Key Features

• 1-1/2 inch cutting diameter for full-bore holes without pilot drilling
• 4 inch depth of cut for deep-reach applications in thick structural material
• Carbide-tipped construction for extended tool life on hard and abrasive metals
• 3/4 inch shank with 2 flats for positive engagement in mag-drill chucks
• Oxide straw finish provides heat resistance during high-cycle cutting operations
• Compatible material applications include aluminum, mild steel, stainless steel, and general steel

Compatibility

Designed for use with magnetic drill presses accepting a 3/4 inch flatted shank. Suitable for cutting aluminum, mild steel, stainless steel, and general steel.

Installation Notes

This cutter is installed and operated by qualified metalworkers, fabricators, or maintenance machinists using a compatible magnetic drill press. Ensure the workpiece is clean and the mag-drill base is fully energized and seated securely before beginning the cut. Use cutting fluid or coolant appropriate for the material being drilled to extend cutter life and maintain cut quality. Never exceed the rated depth of cut or force the cutter through material at a feed rate that causes excessive heat or chatter.
