Powerful 13-Amp Motor
The drill is equipped with a 13-amp motor designed for demanding metalworking applications. The motor supports drilling with both annular cutters and twist drill bits, giving users flexibility when working with different hole sizes and materials.
Two-Speed Gearbox
The two-speed gearbox allows the operator to select an appropriate speed for the accessory being used:
- 475 RPM: Optimized for annular cutters.
- 730 RPM: Designed for twist-drill applications.
The speed selection is part of the tool's quick setup system, allowing users to switch applications without extensive adjustment.
1-5/8-Inch Drilling Capacity
With a maximum 1-5/8-inch annular-cutter capacity, this electromagnetic drill is built for large-diameter holes commonly required in structural steel fabrication, installation, maintenance, and heavy-duty metalworking.
Its portable format allows the drill to be positioned directly on large steel workpieces instead of requiring the material to be transported to a stationary drill press.
3/4-Inch Weldon Quick-Change Arbor
The 3/4-inch Weldon quick-change arbor is designed for compatible annular cutters. Its quick-change configuration helps reduce setup time when changing cutters.
The kit also includes a 3/4-inch Weldon-to-1/2-inch chuck adapter, expanding the drill's compatibility with suitable twist drill bits.
Electromagnetic Base
Unlike a permanent-magnet drill, the 4272-21 uses an electrically powered electromagnetic base. The magnetic base is designed to hold the drill against suitable ferrous workpieces while the tool is operating.
For best holding performance, the mounting surface should be clean, flat, and suitable for magnetic attachment. The manufacturer's specifications and operating instructions should always be followed for the specific workpiece and drilling position.
Auto-Stop Lift-Off Detection
The Auto-Stop Lift-Off Detection feature is designed to help protect the operator if the drill loses magnetic contact with the work surface. This provides an additional safety measure during demanding drilling operations.
Tool-Free Adjustments
The drill incorporates several tool-free adjustment features designed to simplify setup:
- Cutter-to-twist-bit adjustment
- Motor-head adjustment
- Feed-handle adjustment
These features help operators configure the machine more quickly when changing drilling applications.
LED Work Light
An integrated LED light helps illuminate the drilling area, making it easier to see the workpiece and drilling point, particularly in areas with limited lighting.
What's Included
The 4272-21 kit includes:
- 1 × 1-5/8 in. Electromagnetic Drill
- 1 × Safety Strap
- 1 × Lubrication Spray Bottle
- 1 × Chuck Key
- 1 × Carrying Case
- 1 × 3/4 in. Weldon-to-1/2 in. Chuck Adapter
- 2 × 1 in. Retractable Pilot Pins
Ideal Applications
The Milwaukee electromagnetic drill is suited to demanding applications such as:
- Structural steel fabrication
- Steel installation
- Metal fabrication
- Industrial maintenance
- Equipment repair
- Heavy-duty workshop drilling
- Structural and infrastructure work
- Large steel component drilling
Its portable magnetic design is particularly useful when drilling large or fixed steel components that cannot easily be moved to a conventional drill press.
Safety and Proper Use
Because this is a high-powered magnetic drilling machine, proper setup is essential.
- Inspect the drill, cord, arbor, cutters, and accessories before use.
- Make sure the electromagnetic base is properly engaged before drilling.
- Keep the mounting surface clean and free of debris that could interfere with magnetic contact.
- Use the supplied safety strap as directed, particularly for elevated or demanding applications.
- Keep hands, clothing, and other objects away from rotating components.
- Wear appropriate eye and hearing protection.
- Use suitable cutting lubricant when required.
- Disconnect the tool from power before changing accessories or performing maintenance.
- Never exceed the recommended capacity of the drill, cutter, or workpiece.
