Jancy Magnetic-Base Drills for Hollow-Core Cutters
 |  |  |
Style A | Style B | Style C |
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 electromagnetic base attaches to flat ferrous surfaces (such as steel and cast iron). These drills also have a valve to adjust coolant flow. Holding force (also called drill-point breakaway) is calculated against a 1" thick steel plate.
Styles A and B—Styles A and B have a fixed base.
Style C—Style C drills adjust 7° left and right.
Magnetic-Base Drill Chucks and Adapters—Chucks and adapters (sold separately) allow these models to accept standard drill bits.
