The BDF452 delivers 450 in.lbs. of Max Torque and 285 in.lbs. of PTI Torque, yet it weighs just 4.1 pounds compared to the BHP454 at 4.9 pounds. Less than a pound of difference but use it for a day and you'll find out.

The Makita BHP452HW is a two speed drill that can produce 0-400 rpm at low level and up to 1500 rpm at the high setting.  This makes it perfect for screwing in decks and then turn around and drill big holes into wood.

Like a lot of other Mikata cordless drills the BDF452 offers a built in L.E.D. light that illuminates the work area for more efficient work.  It is located above the trigger and points directly to where you are working.

This Makita is part of the LXT series which means you are getting cutting edge lithium ion 18V battery technology.  It comes with a smart charger which only requires about 30 minutes to fully charge your battery.  This translates to stay on the job longer and finishing sooner because you don't have to wait a half a day for your batteries to charge up.

One option that you should consider is the Rapid Automotive Charger. This auto charger is for 18V LXT and 18V Compact Lithium-Ion batteries that plugs into 12V DC sockets equipped in most automobiles and trucks for added mobility.
