In .498" shank is bigger better? More $ more power? We test the infamous CP717, the new comer Thor 498K bored over 7X air hammer and a massive 9X CP4289 to find out. Any bigger and our air hammer dyno is going to be kaput and all future data lost. So let's see who takes the top spot! As always, Torque who started this channel is working in product development for Astro Tools who also make the 498K air hammer in this video. TTC is not the only testing out there, always consider multiple sources! ~We earn from qualifying Amazon affiliate links here ~
