Hammerhead 12V Lithium-ion Right Angle Impact Driver/Auto Hammer


We were contacted a while back about this new concept called the Hammerhead.  After hearing about the concept, we thought it was pretty cool and decided on trying one out.

The Hammerhead is a cross between an autohammer and a right angle impact.  Yes, it does both.  All the user has to do is move a switch located on the top and you can change between the two tools.  When you’re using the autohammer feature, the tool comes with a bit you insert into the hex collet.  When not in use, you can store it on the tool.  When you want to move to an impact, just take the bit out of the 1/4″ quick release collet and insert the bit you need.

The Autohammer is powered by a 12 volt Lithium-ion battery which takes 30 minutes to fully charge and 5 minutes to charge to 10%.

Nail capacity up to 8D (2-1/2”)
Wood/drywall screw capacity up to #8×3”

So is this tool for you?  Well only you can decide that.  If you deal with small spaces, you might find a need for this tool.  That’s where this tool could shine.  Personally I own a craftsman Autohammer and have never used mine.  Now that is not a knock against the Hammerhead, but it’s just a very specific application you would use for this.  One downside to this tool is the battery is integrated into the tool.  So if the battery dies, you can’t change the battery and insert a new one to finish the job.  Also if the battery fails, the tool fails.  While it is backed by a two year warranty, three if you register it, you are still down without a tool.  Now it’s hard for me to sit here and really tell you about this tool.  This tool is new to the market, so I am not sure how well they are built, if they have a defect or use an inexpensive battery that doesn’t last.  While it feels solid, I don’t really know anything about the company or the tool.  Currently it is sold only at Lowes.


  1. Sorry to hear you have a Craftman autohammer 🙂 The only time I used mine was to play with it to nail scrap 2×4’s. Never really found a use for it that a trusty hammer could do faster. I fell for this gimmick I really try to stay away from these things know. I agree that it could be the best tool out there, but if you can find a use for it why invest? I saw it at Lowes several weeks ago for $30 bucks, still to expensive I thought. Now, let me see it I can find my autohammer to play with & drive nails into scraps. Maybe not, nails are expensive now a days & a hammer is cooler to use anyway. Laters TIA

  2. I think I’ll stick with my Craftsman R.A.I.D. (right angle impact driver) and AutoHammer. Like you I never use my AutoHammer but my 76 year old father thinks it the best tool ever invented!

  3. I do see allot of use in a tool like this at least the impact driver portion. If this were made by one of the major manufacturers and had a replaceable battery I would buy it. I bought the Rigid Jobmax just so I could get their 90 degree impact head for it. Has saved me on the job more than a few times
