HMD904
 
Permanent Magnet HMD904
All the same great features of the HMD904 with an added layer of safety and even more versatility. The permanent magnet easily operates with an on/off knob and grips to the steel without the need for electricity. Plus the unique structure of the magnet allows it to be used for pipe drilling without an adapter. The HMD904 can use all the same accessories as the other HMD904's and is made in the USA.
