Milwaukkee shockwave impact duty driver bits are to be most perdurable, best try-on driver bits on the market. The opitmized shockzone geometry is for each tip type to provide up to 30x more torque vs. past impact bits.The exact fit coutom machined tip prervente stripping and reduce wobble while the custom alloy 76 steet and trademarked heat treat maximizes resistance to wear and shock. shockwave driver bits are to driver exreme durabitity for the demanding applications.
