About

The Mag Pen is a small handheld magnetic sweep designed to make it easy to do light cleanup up iron based materials from a machine or working surface safely. The idea came about after doing some hard milling on some 4140. This was done on a cnc machine and no amount of air blasts, brushes or vacuuming was easily going to clean it out of the t-slots, or machine vise. After spending several weeks of picking steel out of the nooks of the machine we decided there has to be an easier way. A magnet was a clear choice but there wasn’t a magnetic sweep on the market designed to get into tight spaces and to be a simple small form factor. We decided to build our own.

The tool features a 5/16 tip made of raw aluminum to easily get into tight places and pull out chips without scratching the cast iron, or steel of machines. The cap is magnetically retained and offers enough distance from the enclosed magnets to put the pen in with other tools without having annoying retention problems.
