Milwaukee 49-57-4370 Steel Hawg Annular Cutter 4-3/8 in

Product Description

The MILWAUKEE 49-57-4370 is a threaded Steel Hawg annular cutter designed for use with electromagnetic magnetic drill presses in metal fabrication and structural steel applications. Built with abrasion-resistant carbide teeth and an alternating tooth form geometry, this cutter produces fast, clean holes up to 2 inches deep in steel, stainless steel, cast iron, and aluminum. The 4-3/8 inch cutting diameter uses an M18 x 1.5 metric threaded shank, and a spring-loaded, self-ejecting centering pin improves accuracy and speeds up plug removal between cuts. Licensed electricians, ironworkers, pipefitters, and mechanical contractors working with heavy steel fabrication rely on this style of cutter for hole-making tasks that would otherwise require multiple twist drill bit passes.

This annular cutter is suited for commercial and industrial settings where large-diameter holes must be cut through structural steel, plate, or pipe flanges. It is compatible with most electromagnetic drill presses that accept a threaded shank. For Milwaukee mag press models, use arbor 49-57-0030 with the 4262-1 magnetic drill press or arbor 49-57-0010 with the 4292-1 magnetic drill press. The cutter is also compatible with a No. 3 Morse taper arbor assembly 49-57-0010. Each unit is sold individually.

• Alternating tooth form geometry cuts up to 3 times faster than standard twist drill bits
• Abrasion-resistant carbide teeth extend cutter life and produce a cleaner hole finish
• Spring-loaded self-ejecting pin serves as a centering pin and speeds plug removal
• M18 x 1.5 metric threaded shank fits most electromagnetic drill press arbors
• 2 inch maximum cutting depth in steel, stainless steel, cast iron, and aluminum
• Compatible with No. 3 Morse taper arbor assembly 49-57-0010

Compatibility

Compatible with most electromagnetic drill presses that accept a threaded shank. For Milwaukee magnetic drill presses, use arbor 49-57-0030 with the 4262-1 or arbor 49-57-0010 with the 4292-1. Also compatible with No. 3 Morse taper arbor assembly 49-57-0010.

Installation Notes

Installation and use of annular cutters should be performed by qualified tradespeople familiar with electromagnetic drill press operation. Always secure the mag press to the workpiece and confirm the magnetic base is fully energized before starting a cut. Power down and disconnect the drill press before changing or inspecting the cutter. Apply cutting oil to the cutter and workpiece to reduce heat buildup and extend cutter life.
