Here’s a fun fact about me, I’ve been around construction tools and machinery all my life.  My dad is a Master Carpenter and General Contractor so I’ve pretty much seen power tools evolve over the last 20+ years.  I even remember his first cordless drill, which barely had enough power to drive a screw without pre-drilling.    So this months favorite tool is the Bosch PS40-2.  The Bosch PS40-2 is a 12-volt Lithium-Ion Impact Driver that is very well balanced, light weight and very powerful.  If you have never used an impact driver, you’re in for a treat.  The sound of it “impacting” when driving a screw or bolt is normal (some think the sound is a defect).    Don’t judge it by it’s compact look this drill is a monster… it’s small enough to carry with your and use in tight places but powerful enough to drive a screw without drilling.  The battery life is also great… I typically charge it and can use it for the full day before needing to recharge.  Just keep in mind that this is a driver, not a typical “drill” so if you want to drill something this isn’t the best tool for the job.  Bosch offers a PS30-2A (drill/driver) for that kind of job.

Here are some specs on the PS40-2:
- Hammer and anvil system produces 800 in-lbs of torque
- Delivers 1,800 RPM/3,000 BPM with 60 per cent more torque than 18V drill-driver; 800 in.-lbs of max torque.
- 3 LEDs illuminate work area for use in dark areas.
- Spring-Loaded Impact Mechanism.
- Aluminum gear housing with protective rubber front and a 1/4″ hex drive with quick release.
- Ergonomic Soft Grip Handle; bumpers on side of tool.
- Variable speed trigger.

The Bosch PS40-2A also will make a GREAT father’s day gift!
