    Milwaukee Magnetic-Base Drills for Hollow-Core Cutters

    Image of Product. Front orientation. Magnetic-Base Drills. Milwaukee, Style B.

    Style B

    These drills work with hollow-core cutters to cut only on the periphery of the hole and produce a solid slug. This allows for a faster and easier cut than drilling with standard drill bits. Also known as magnetic core drilling machines.
    They have a feed handle that mounts on the left or right side of the drill. The magnetic base attaches to flat ferrous surfaces (such as steel and cast iron). Holding force (also called drill-point breakaway) is calculated against a 1" thick steel plate.
