Question: Is the Impact gun (DC825) variable speed?  Or is it full speed the instant you pull the trigger...
Document: Pros - drillVery powerful drill, you will be glad it comes with a side handleprecise variable speed controlall functions work as they are supposed togood battery life for NiCadexcellent clutchLED work lightCons - drill:heavy3 speed switch can feel a little vagueplay in output shaftStill a NiCadThe drill/driver works well, is extremely powerful, and has a very secure ratcheting chuck. The hammer function works well, and the variable clutch is precise and easily adjusted. The LED is a nice touch.
After owning the hammerdrill for only 45 days, the reverse button on the drill stopped working. It was very difficult to switch between forward and reverse. When letting go of the trigger the drill would not immediately stop; it would slowly some to a stop instead of instantly. Something was causing the trigger to not be released all the way and the reverse selector to not be depressed. I've only used the drill 3 times since I've had it. It still looks brand new!
These are the best drills/impact drivers i have ever used. Ive drilled a lot of holes in concrete with the hammer drill. The impact driver is so strong it can break a 3/8" lag bolt if you arent carful. Nice drill chucks. Good battery life too.
I used the 1/4&#34; impact to do all the maintenance on my Rhino last weekend. My only regret is that I didn't buy this tool sooner. Keep in mind though that this a light-duty impact. While fairly stout, it will not do the work of a 3/8&#34; or 1/2&#34; impact.
I received the Hammerdrill/Impact Driver Combo Kit on time. Upon opening the box I noticed the yellow/black bag was slightly torn. I have used the kit three times already and it works great. Just disappointed that the bag was torn.....thus only 3 stars.
While the drill actually has more peak torque than the impact driver, being able to drive or loosen screws the impact can't quite handle, it does not try to twist itself out of your hands with use. Instead it has a hammer mechanism, that applies torque in little impulses, to drive or remove fasteners. If it had a little more power, it would be 5 stars. As it is, it doesn't have any more power than the Craftsman it replaced, which sells for half the price.
If they could tighten that up a bit, when in 'drill' mode, this would be the best cordless drill I ever used.The impact driver is a good one. Compact, yet adequately powered. I like that you can insert bits one-handed into it. Again, the LED worklight is a nice touch. Battery life is good for NiCads, and again, it is heavier than a comparable tool with a Lithium battery.
These are the original workhorse DeWalt Drills.The 18v XRP battery makes these run what seems like forever and the build quality of the tool itself is near bulletproof.Specifically-Pros:Great matched pair. Two Batteries included. A nice touchHuge run time. I know this from owning both the 18 and the 14.4v sets of these1-hour rechargeEven the impact driver can easily drive 4 inch long screws (end on) into 2x4s.
