Line Boring with a Mag Drill vs Power Feed – Video

What this video shows

We run an IRM portable line boring set with our Power Feed, then swap in a mag drill on the same setup so you can see and hear the difference in the cut.

With a mag drill, the drill turns the boring bar and you feed the cut by hand. That works well for lighter or occasional jobs, but the finish depends on keeping steady pressure the whole way through. The line boring power feed advances the bar and cutter at a steady, controlled rate and runs on a standard handheld drill, so the cut is smoother and bore size is easier to control. It's built for machinists who line bore every day.

Both drives work with the same IRM Set A or Set B, so you can start with the mag drill you already own and add the Power Feed later. The end of the video shows our custom tool bits with replaceable inserts.
