Model DP 4700 is an older drill but was built with power in mind.  Variable speed/reversing, stabilizer handle, key, and hook.  Have instruction manual w/parts listing and a no load speed of 0 - 550 RPM.  Caution, you will only use this drill once without the stabilizer handle!  I will guarantee this drill to be the most powerful for its size of any drill I have ever used or your money back.  Give me a call at 785-543-4223, leave a message, or reply to this ad.  Firm on the price and cash.
