and you can use these in many creative ways.....I own a Jancy, now Fein...... and find all sorts of ways to solve my hole making needs......it is the best hole making tool I have ever bought and has allowed me to make hole that I would have thought impossible or too hard to attempt......I even bought a Jacobs style chuck for the drill that allows me to use standard twist drills for small size hole...... even if you are not drilling thick structural type material.....this machine is a game changer.... good example, I build mobil bars for hotels, roll around, about 4x6x3 feet.....from square or rectangle tube....well, the guy I work for will have me make the frame, then tell me, oh yeah we need hole drilled to hold the side inserts, etc on.....that sometimes means drilling over 100 holes.....I am over 65 years old and drilling with a hand held drill is not for me..... I place the Mag Drill on the steel table and just move the completed frame around ...... makes simple work.....I also carry a 3/8x6x18 inch steel plate on location, and attach the drill to the plate, then clamp small parts like 3x3 angle that is only 3 inches wide to the plate with a clamp, and I have a little drill press in the field...... By the Way,,,I think Fein made the first motorized electric drill back at the turn of the last century..... correct me if I am wrong,,,,, cheers from an old weldor in Florida, Paul
