- Speed: 475/730
- Cutter interface: 3/4-inch Weldon quick-change

When it belongs on your shortlist
The first comparison should be with the 4274-21 because magnet design separates the two in a way that headline motor size does not. If you are evaluating a used or discounted listing, confirm the exact model on the unit, not just in the seller's title. Then compare the accessories you need for annular and twist drilling.
A workshop with dependable power may be willing to consider an electromagnetic base, while a field job may make power management a more prominent concern. Neither setting excuses an unsupported attachment. Evaluate the working surface, available restraint point and method of controlling the workpiece before deciding which magnet design belongs in the shortlist.

Check AmazonThe limitation to check first
Do not credit the 4272-21 with the 4274-21's permanent-magnet hold during power interruption. The source page confirms Auto-Stop lift-off detection, but that feature does not change its magnet type. Likewise, the supplied spray bottle should not be described as an integrated through-spindle coolant tank without exact documentation.
Questions, answered
Does 4272-21 use a permanent magnet?
No. Milwaukee identifies 4272-21 as its electromagnetic drill. The closely related 4274-21 uses the permanent magnet.
