Powerful 13-Amp Motor
At the heart of the drill is a 13-amp motor designed to provide the power required for demanding metal-drilling applications. The motor supports both annular-cutter and twist-bit drilling, giving users greater flexibility when working with steel components.
Two-Speed Gearbox
The two-speed gearbox provides dedicated operating speeds for different drilling applications:
- 475 RPM – optimized for annular cutters.
- 730 RPM – suited to twist-drill applications.
The speed selection can be adjusted without tools, making it easier to switch between drilling methods while working.
Permanent Magnetic Base
Unlike conventional electromagnetic magnetic drills, the permanent magnetic base operates without electricity. This allows the drill to maintain its magnetic hold even if power to the tool is interrupted.
The partial magnet mode can also be engaged with a quarter-turn of the magnet knob, allowing easier positioning and hole alignment before applying the full magnetic hold.
1-5/8-Inch Drilling Capacity
The drill is designed for applications requiring holes up to 1-5/8 inches with suitable annular cutters. This capacity makes it well suited to structural steel fabrication, installation work, equipment maintenance, and other applications involving heavy steel components.
3/4-Inch Weldon Quick-Change Arbor
The 3/4-inch Weldon quick-change arbor is designed for annular cutters and allows cutter changes without unnecessary setup time. The included 3/4-inch Weldon to 1/2-inch chuck adapter also expands the tool's versatility for compatible twist-drill applications.
Auto-Stop Lift-Off Detection
The Auto-Stop lift-off detection system is designed to respond if the drill loses its magnetic hold on the workpiece. This feature provides an additional layer of protection when drilling in demanding positions.
The permanent-magnet design also makes this model particularly suited to vertical and overhead steel drilling, according to Milwaukee.
What's Included
The Milwaukee 4274-21 kit includes:
- 1 × 1-5/8 in. Magnetic Drill Kit
- 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
This magnetic drill is designed for demanding metalworking environments such as:
- Structural steel fabrication
- Steel erection and installation
- Metalworking shops
- Industrial maintenance
- Equipment repair
- Bridge and infrastructure work
- Heavy fabrication
- Vertical and overhead steel drilling
Its portable magnetic-drill format allows users to bring the drilling machine directly to large steel workpieces instead of moving the workpiece to a conventional drill press.
Practical Design for Jobsite Work
The tool combines a substantial drilling capacity with features intended to reduce setup time. Tool-free adjustments, the quick-change arbor, two-speed gearbox, and included carrying case make the 4274-21 practical for repeated drilling operations in fabrication and maintenance environments.
Its approximately 30.5-pound tool weight reflects its heavy-duty construction and magnetic holding system, so proper handling and the included safety strap should be used according to the manufacturer's instructions.
Safety Considerations
Magnetic drilling involves rotating cutting tools and heavy equipment. Always follow Milwaukee's operating instructions and applicable workplace safety requirements.
- Secure the workpiece before drilling.
- Use the supplied safety strap as directed.
- Verify that the magnetic base is properly engaged before starting.
- Do not operate the drill on unsuitable or insufficiently thick magnetic material.
- Keep hands, clothing, and other objects away from rotating components.
- Use appropriate eye and hearing protection.
- Apply suitable cutting lubrication when required.
- Disconnect power before changing accessories or performing maintenance.
- Inspect cutters, pilot pins, arbor components, and the power cord before use.
Why Choose the Milwaukee 1-5/8 in. Magnetic Drill Kit?
The Milwaukee 4274-21 is built for professionals who need a portable solution for large-diameter drilling in steel.
