Magnetic Drills

Magnetic drills are portable tools that use a powerful electromagnet base to attach securely to a ferrous metal surface, enabling precise and stable drilling in various positions including horizontal, vertical, and overhead. They are primarily used for drilling large diameter holes in steel and are widely used in steel fabrication and industrial construction.
Key Features and Operation
Magnetic drills work by core drilling using an annular cutter which only cuts the periphery of the hole, leaving a "slug" of metal in the center. This method is faster and more efficient for large holes in metal compared to conventional twist drills.
Portability: Their compact and lightweight design allows them to be brought to the workpiece on a job site, a major advantage over traditional, stationary drill presses.
  • Stability: The powerful magnetic base (e.g., 2,900 lbs of force) provides high stability, ensuring accurate and burr-free holes.
  • Safety: Key safety features include a safety strap (always recommended for operator safety and to prevent falling during power loss) and often an automatic shut-off function if the magnetic base loses sufficient contact with the material.
