Bosch 18-Volt Litheon Impactor - Review
Bosch recently added an 18-volt impact gun to their Litheon line and we've had our hands on one for about three months now. We skipped any staged testing protocols (i.e. how many 3" lag screws can it drive) and just brought it to work. So for the last 14 weeks we have treated this tool in such a way that we now understand what red-headed step-children have to go through. Instead of carrying the gun down a ladder, we threw it. Instead of packing it up in its case, we lobbed it in the back of the truck, instead of putting it under a tarp, we left it out in the rain. If this thing is going to be a job site gun, it's got to survive basic training. So on to our thoughts...
First, the Bosch comes with a few practical features, but thankfully, nothing audacious or gimmicky. It's got an LED, a nice little bit holder at the base of the handle and a belt clip that can be placed on either side of the handle (with just the removal of one screw), depending on the task at hand, or whether you're a righty or a lefty. The belt clip is nice, but it's one of those things that will hop off your hip going down a ladder or crouching over. It's handy for a quick holster, but nowhere near as secure as a Prazi Monster Hook, so we would still recommend picking up one of those or something like it.
And as for day-to-day functionality, the Bosch Impactor is really a top-notch gun. It laughed at our rough treatment and easily and consistently drove 6" Timberlok screws into wet 4x6s. It's shorter and stubbier than our old Makita, and it feels better in the hands.
Our one gripe with the tool is that the nose of the gun has a protective rubber sheath on it, which is great and prevents surface marring in tight spots, but the piece is removable and somewhat loosely fit. On more than one occasion, the piece would come slightly loose and snag on something (one time even causing the gun to hop off our hip and fall onto a finished floor). Why not just make the piece permanent? This might sound like nit-picking, but with Bosch so close to making a perfect impact driver, this loose flap of rubber really bothered us.
And as always, Bosch provides a great case with the tool, capable of holding extra batteries and bits and with enough room left over for a few hand tools as well.
We also had the opportunity to check out the difference between the Bosch slim pack and fat pack Litheon batteries. Obviously, the fat pack are going to be stronger (they were) and last longer (they did), but it all comes at the cost of a heavier unit (and a more expensive one). Both batteries held charges for quite some time, but the fat pack were tremendous on this front. Sometimes we would go a few days on one battery. Keep in mind, we weren't doing production work, but still, under the same load, we would have had to hit up the Makita charger at least three or four times. The way we see it, there is really no way you'll ever find yourself in a situation where you're standing around holding a dead battery, waiting impatiently for the other one to charge.
The bottom line here is that this is a fantastic tool. It's durable and powerful, and to be honest, this tool integrated itself so well into our life that we forgot we were reviewing it. If Bosch keeps the battery line alive, this is a tool that you could potentially have for a long, long time. But this kind of quality doesn't come cheap. The Bosch Impactor costs anywhere from $250 to $380 depending on the package you get. You can get the gun with either 2 fat pack batteries or two slim pack batteries. Our opinion on this is that if you're going to be working the gun pretty hard, the fat pack are worth it, but if you're an electrician or someone who won't be using it full time or for particularly strenuous tasks, the slim packs should do you fine.
