The Projahn 4x4 Zentro+ hammer drill bit was put under the 'hammer' at Garrards.  We put it up against the main selling bit, which one bores the best hole?

All brands’ bits look the same, feel the same but they are not made the same.  Projahn is a German company which produces high quality precision tools and Garrards are proud to distribute their range of tools throughout Australasia.  The bits come in different types of shanks depending on the purpose of the bit - SDS Plus, SDS Max, Straight, or Hex shanks.
