Hougen Magnetic Drills are some of the most popular on the market and arguably some of the best. Doug Hougen patented the first Rotabroach Annular Cutter back in 1973 and since then a whole industry has obviously taken off. If you are in the market for a new Mag Drill now is a good time. Until the end of this month 2/28/2011, you can take advantage of this mail-in rebate promotion for your choice of: Drill Chuck & Adaptor, Twisted Drill Adaptor Kit, 1” Arbor Extender or 2” Arbor Extender. The promotion is good with the purchase on any of the Hougen HMD904 or HMD914 models.
