The Milwaukee 1-5/8 in. magnetic drill will deliver the fastest drilling and strongest hold on 1/4 in. steel in its class. It's 13 amp motor delivers the fastest drilling w/ annular cutters or twist drill bits. Equipped with a 2-speed gear box the tool can be adjusted tool-free between annular cutters at 475 RPM and twist drill bits at 730 RPM. The permanent magnet base operates without electricity for continuous magnetic hold even during power interruption. Activating partial magnet mode with a 1/4 turn of the magnet nob allows for faster, easier hole alignment. This magnet technology makes the Milwaukee 1-5/8 in. magnetic drill better for vertical and overhead drilling applications than traditional electromagnetic models.
