I purchased this hammer drill after the death of my Black & Decker 18v Firestorm. Initially, I had considered similar products from Matika and DeWalt, wanting the additional capability of the hammer action, with the smaller bulk of the 14.4v battery. The Porter Cable GTF comes in fairly robust case, complete with a diagnostic charger, stabilizing handle, 2 batteries, driver bit and different size (S,M,L) adjustable hand grip inserts. I found the drill some what hefty, with it's balance just forward of the hand grip; which is the only reason I did not give it 5 stars.
Offering 420 in-lbs of torque (50 in-lbs more than the Matika and 20 in-lbs more than the Dewalt 14.4v hammer drills) it has plenty of power and will easily snap the head off a 4" deck screw driven into a railway sleeper. The high/low settings will give you 450-1400rpm, and in hammer action 18500bpm. Battery life was excellent, allowing me to do several hours of deck work before swapping batteries. The charging unit can recharge your dead battery in approx. 1hr, it will also analyze the condition of your battery for optimal performance.
As mentioned before, I felt this was heavy drill. It does not balance as well as the Dewalt or Matika, which is probably why it feels heavier, though it certainly not unmanageable; much smaller than the enormous 18v Craftsman drill, that thing is a whopper. However, because of it's forward weight, using the hammer action vertically is really easy. There is also the option of swapping out the hand grip inserts, which helped reduce fatuige on the hands and wrists. Ergonomically speaking, fine. The stabilizer handle screws into either the left or right side of the drill which is a tremendous help when using the hammer action.

I am a full-time carpenter.

This is a professional quality drill/driver, with metal gears, heavy-duty trigger switch, ratcheting chuck with carbide teeth. It has heft and although some might complain about its weight, anything that generates over 400 in. lbs. of torque and doesn't fall apart after 40 hrs. of hard use HAS to weigh something, right?

I read an April 2005 review on 'premium' vs. 'homeowner' grade cordless drills and was interested to see that in nearly every photo of a disemboweled premium drill, said premium drill was the Porter-Cable. It's built to last.

Here's what to watch out for:

1) If you charge the batteries, then don't use them for a few days, your amp hours will be far lower than if you charge the batteries and use them the same day. I don't get quite as much run time out of the batteries as I would like, but I am doing mean things to my drill, like running a 3/4" x 16" masonry bit in hammer/drill mode and leaning into the poor little drill, driving 1/2" x 12" lag screws into pressure-treated wood, drilling holes through 20 oz. copper and tin in -5˚ weather....and so on. When used for what I imagine is a more appropriate application, like driving sheetrock screws into sheetrock, the batteries last long enough for me to wonder when they'll die so I can take five.

2) The HIGH/LOW switch. Works great, but one day I somehow left it in between settings: i.e., in the middle, not on HIGH or LOW, and the drill made a horrendous racket and would not drive anything to save its life. Convinced the drill was completely shot, I began hunting for the case so I could take it back to Home Depot and give them puppy dog eyes.

UPDATE: I have used the drill a few times and I could not be happier. I like this drill so much that when it came time to by a reciprocating saw I went with a PC (See my other reviews). OK...I have not even used the drill yet but opening reaction is great. I ordered mine off of because I couldn't find a better price, only one hardware store in the Twin Cities area had the drill in stock and wanted $25 more than So saving $25 off of cost, do not have to drive 25 miles to store, do not have to pay tax and get free shipping, only down fall is the 10 day wait.


Case seems sturdy with metal case latches, not cheap molded plastic. Storage for extra bits and manual slot is a definate plus. All batteries, side handle, charger and of course drill fit very well. Problem with the case is the extra "grip to fit" (GTF) plates do not fit in the bit storage compartment.


My drill came with the large GTF insert, that was changed quickly. I have small hands so the small insert is very nice for myself. GTF is great because a friend of mine with pretty large hands found the large insert to be helpful so this drill is not a one size fits one its a many sizes fits many. Switching from forward to reverse is a snap, a bit clip on either side of the drill along with the side bar that secures tightly to either side too. Balance is a little forward moving but that is good for drilling and with the hammer drill option what do you really expect. The battery removal is not as easy for this drill compared to many other brands. The battery slides horizontally into position with a smaller release button.
