Decide whether a magnetic drill can be secured to steel, stainless steel or aluminum before choosing the cutter and operating setup.

Mag Drill Minimum Steel Thickness: Exact-Model Checks
Compare exact-model minimum steel requirements, full-base contact and thin-plate stop rules before selecting a magnetic drill.
Examples with a documented plate-thickness floor
Evolution publishes a 3/8-inch minimum plate thickness for these two exact US models. That shared number does not approve coated, curved, uneven, non-ferrous or otherwise unsuitable work; check the full manual and surface conditions.
- Evolution S28MAG: The smaller 1-1/8-inch annular-capacity branch; diameter, depth and the mounting-surface requirement must all pass independently.
- Evolution EVOMAG42: The larger 1-5/8-inch annular-capacity branch; its single-speed identity and exact package still need separate confirmation.

Model guide availableEvolution S28MAG
a compact-capacity corded drill for hole schedules that stay within its 1-1/8-inch annular diameter limit
- Annular diameter
- 1.125″ maximum
- Cutting depth
- 2″ maximum
The 2-inch depth figure is separate from diameter, and a 2-inch cutter is not automatically a 2-inch-diameter cutter. Evolution specifies a 3/8-inch minimum plate thickness. The published magnetic adhesion figure is not a lifting capacity or a reason to ignore that minimum.

Model guide availableEvolution EVOMAG42
a larger-capacity alternative to the S28MAG when a single-speed corded machine suits the work
- Annular diameter
- 1.625″ maximum
- Cutting depth
- 2″ maximum
The US product page lists one speed, not two. Do not import a speed range from a different Evolution machine. Its chuck accessory information also distinguishes the chuck from the HTA47 adapter; confirm what the exact package contains before buying a twist-drill accessory.
