Milwaukee 49-59-4144 Tct Annular Cutter 1-7/16 in Hard Metal

Product Description

The MILWAUKEE 49-59-4144 is a tungsten carbide tipped (TCT) annular cutter engineered for fast, clean hole-making in hard metal materials. The cutter features an advanced tooth geometry that simultaneously cuts, clears, and cleans during drilling, reducing heat buildup and chip interference. Its thin-wall design displaces less material than standard twist drills or competing annular cutters of the same diameter, resulting in faster cycle times and burr-free holes. The 3/4-inch Weldon shank provides secure seating in most small and large magnetic drill presses. Installation and operation are handled by licensed machinists, fabricators, and ironworkers working in structural steel, manufacturing, and maintenance applications.

The 49-59-4144 is suited for drilling in hard metals including stainless steel and cast iron. At 1-7/16 inches in diameter and approximately 3.65 inches in cutting length, it handles typical structural and heavy fabrication hole sizes in a single pass without pilot drilling. The cutter is sold individually and is compatible with the ejector pin 49-59-0014, which is required for slug ejection during operation. It is appropriate for both shop and field use with magnetic drill press equipment.

Key Features

• Advanced TCT tooth geometry cuts, clears, and cleans simultaneously for faster holes and longer tool life
• Thin-wall design removes less material per pass compared to standard hole cutters, increasing hole speed
• Rated for hard metal applications including stainless steel and cast iron
• 3/4-inch Weldon shank fits most small magnetic drill presses and large magnetic drill presses with the appropriate arbor
• Compatible ejector pin: 49-59-0014 (sold separately)
• Sold individually, one cutter per unit

Compatibility

Designed for use with most small magnetic drill presses and large magnetic drill presses equipped with a 3/4-inch Weldon shank arbor. Use ejector pin 49-59-0014 for proper slug ejection.

Installation Notes

This cutter is installed and operated by qualified metalworkers, fabricators, or maintenance professionals using magnetic drill press equipment. Before mounting the cutter, ensure the drill press is fully powered down and the magnet is disengaged. Confirm the Weldon shank is fully seated and the set screw is tightened before beginning any cut. Always use cutting fluid appropriate for the base material, particularly when drilling stainless steel or cast iron, to manage heat and extend tool life.
