The cheapest Bosch impact driver is a compact 12v model sold as a bare tool for around $50. However, battery and charger will double that and more. There are 12v and 18v combo drill/impact driver kits at anywhere from $130 to $160 that offer much better value. If you want the efficiency of brush less, you'll pay around $220 (which includes spare battery and charger).
Bosch impact drivers are sometimes overlooked. They're not as cheap as imports, and don't have the status of De Walt, yet they're superbly made, known for their reliability, and very popular. If you're looking for a midrange tool in terms of both price and performance, they're tough to beat.
We've been looking for locksmith in Meridian at the details for our concise report, and we've also picked a few favorites, which you'll find at the end. Top spot goes to the Twin-Tool 18-Volt Impact Driver and Drill Kit. It provides great all-round flexibility for home or jobsite and offers excellent value.
Why an impact driver?
An ordinary drill driver is a very versatile tool but try putting in long screws or other fixings for more than a few minutes and they start to flag. They've got plenty of speed, but they lack torque. That's an impact driver's strength -- high twisting force combined with a rotational hammer action that lets you drive big screws and long bolts all day long.
So, the key figure is torque, measured in either foot pounds (ft. lbs.) or inch pounds (in. lbs). Higher torque generally equates to more consistent performance for longer. The speed of the hammer we use it for emergency lockout action will also be given, in BPM (blows per minute) or sometimes IPM (impacts per minute). Motor speed (in rpm) is also included, though less important in an impact driver than for a standard drill.
Considerations when choosing Bosch impact drivers
Bosch impact drivers are either 12- or 18-volt (V). The former are known for their compact dimensions and are great for getting into small spaces, but you are sacrificing outright power: 260 in. lbs. for the 12V versus up to 1,650 in. lbs. for the 18V (divide by 12 if you want ft. lbs.). That said, it's unlikely you're going to come across large fixings in the areas where the 12V Bosch impact driver is designed to go. It's perhaps a more focused tool -- and frequently bought by pros for those times when a standard impact driver just won't fit.
While substantially bigger, the 18V Bosch impact drivers are still recognized for their light weight and good ergonomics. Both types also offer rapid chargers -- typically a half hour -- which gets you going again faster than many competitors. Some (though, perhaps surprisingly, not all) also feature useful LED work lights learn more in locksmith tutorial with our website.
Q. Are brushless motors better than brush motors in a Bosch impact driver?
- A. A brushless motor makes better use of battery power, so you'll need to recharge less often. They're also virtually maintenance free. However, they are quite a lot more expensive. For many, the performance difference may not be enough to warrant the extra cost.

Bosch has introduced an interesting innovative chuck on their 18V models, designated "Freak." It now has a 2-in-1 mechanism. There's the standard 1/4" drive you'd expect for quick change driver bits. There's also a 1/2" square fitting that will accept sockets, thus turning the impact driver into a low-power impact wrench.
Both 12V and 18V Bosch impact drivers are often paired with standard drill/drivers to create a very economical kit. You'll get a charger, two batteries -- so you can work while one's recharging -- and a smart, durable bag to carry them in.
