Perfect combination of weight and power.
By rob smith
I bought this model about 6 months ago and am impressed with its ergonomics,weight, and decent power. I was looking for a new cordless to add to my collection of drills and narrowed my choices down to this drill and the 12 volt Makita 6217DWDEX. The Panosonic is about a 1/4 lbs lighter- at 4 pounds, has a 1/2" chuck versus a 3/8" chuck, and comes with 3amp ni-mh batteries versus 2.6 amp ni-mh for the Makita. Why a 12 volt? Because of weight. What's been happening to cordless drills over the last 2-3 years is ridiculous. The 18 and 24 volt models are now weighing in at around six pounds, are a foot long,and cost twice as much as a good quality high amp corded drill. Torque? How much do you need? More on that later. Anyway, let's talk about this Panasonic drill. The build quality is excellent. The seams line up perfectly, decals are put on straight, and there were no flaws in its apperance. The grip on this drill is made of a "grippy" rubber which prevents slippage if your hands are sweaty. This "grippy" rubber handle runs up the back of the drill. This could provide a little bit of cushioning protection if you accidentally drop the drill onto a hard surface. The 1/2" keyless ratcheting chuck grips bits very tightly. I haven't had any round shank drills spin on me. I checked the run out of the chuck with a gauge pin and Starrett test indicator and obtained a reading of .004" runout. Quite acceptable for a hand held drill. The 3 amp batteries have ventilation slots in the bottom. This is an important feature because the number one enemy of batteries is heat. Excessive heat will kill batteries. This heat is generated when recharging batteries or if the tool is under a very heavy load. The battery life is excellent so far. I've driven over 300 number 12 screws, 2", on a single charge into treated deck lumber. I've also used a 1 inch spade drill to drill through several 2" thick floor joists and the drill hasn't bogged down. One thing I did notice is that the drill handle gets hot under extended use. The battery doesn't get hot, just the handle and the bottom of the drill housing. This concerns me a little. Heat kills motors eventually. I'll have to keep an eye on this. The batteries have an excellent "shelf life." I've left one of my batteries in the case without charging it for 4 months and it still has a strong charge. On to rpm, torque, and the clutch. This drill like most has two speed ranges-low, up to 400rpm and high, up to 1300rpm. The trigger on this drill is average. What I mean is that once the trigger is depressed about 2/3rds of the way the drill kicks into maximum rpm. I would like to have a more sensitive trigger. This is my only major complaint about the operation of this drill. By the way, the electric brake on this drill is fabulous! It stops the drill so quickly that the drill actually twitches in your hand when you release the trigger. It's instantaneous! There are 18 clutch settings. The clutch collar clicks solidly when adjusting the clutch and doesn't jump out of position. The torque rating on this drill is advertised to be 293 in. pounds in low gear with the clutch locked out. This is wrong! The actual torque is 199 in. lbs. The 293 in. lbs. is what Panasonic calls its "free load" torque. This "free load" torque is based on mathematical calculations that consider the gear train, magnets in the motor, electrical motor efficiency, and amperage provided by the batteries. It's a theoretical measurement. Under load-when work is actually being done- the actual torque is about 30% less than the advertised torque. What! Don't worry, Dewalt, Makita, Bosch, and Milwaukee, all the premium brands, advertise in the same manner. It's deceptive and unethical (part of the "torque war" that's going on right now), but helps to explain why when a group of 12volt, or 14.4 volt, or 18 volt drills are tested, they are all nearly identical in performance. Some may drill a few more holes, some may drive a few more lag bolts, but the results are pretty close to each other. I knew the torque of this drill was less than advertised before I bought it and wasn't too concerned about it. 199 in lbs. will easily twist the heads off of 10# wood screws if you don't pre drill holes- I've done that. Here's a tip. Whatever the advertised torque is on a cordless drill- subtract 30% from it to get the actual torque. One last comment about torque and this Panasonic. This drill has a feature called "full torque speed control." This means you get the same amount of maximum torque in low range with the clutch locked out no matter how far you depress the trigger. You get the same maximum torque at 70 rpm as you do at 400rpm. This provides great control when driving fasteners. You don't have to "open up" the rpm's to get that extra torque to seat a stubborn screw or lag bolt. My final conclusion about this drill is that it is well built, lightweight, has enough torque for 95% of your jobs, and has unbelievable battery life. Why lug around a 6 pound 18 volt or 24 volt drill all day when a compact 12 volt will handle almost any fastening or drilling job you encounter? I see a lot of electricians and hvac people use Panasonic 12 volt drills, and I understand why. Nobody wants to stand on a ladder and hold some behemoth drill overhead all day. I would rate this drill as 4- to 4 1/2 stars. I think the trigger should be more sensitive and I am a little concerned about the drill becoming hot under extended use, but I think it has the best combination of weight, ergonomics, battery life, and torque of any compact drill on the market.

The best cordless driver for the money-just buy it!
By Mediahound
This is the best driver/drill out there for a number of reasons such as; it has a sturdy chuck that securely holds even the smallest of bits. I had a Makita previously and with small bits, it would often loosen on it's own-very annoying. It runs very smoothly, has NiMH batteries (don't even bother with something that uses NiCAD), and it's much lighter and easier to hold than the 15.6v version-try holding the 15.6v version above your head for a while and you'll see what I mean.This Panasonic 12v packs plenty of punch for everything but the most severe industrial jobs. Among those in the know, Panasonic is regarded as the best maker of cordless drivers. The combination of reliabilty, ergonomics and smoothness is why.This driver is perfect not just for usage around the house as a powerful cordless screwdriver and drill, but it can also quite effectively be used in industrial/contractor situations with no problem at all. I'm a photographer and just used this driver to install frame mounting hardware to the backs of about 100 picture frames for a corporate client and I was extremely pleased every time I reached for it-it's not too heavy, I didn't worry about the chuck coming loose or having the unit fail. I can't say this much about other brands I've owned in the past.

By Jonathan Peck
This is an excellent drill. At 12-Volts this Panasonic packs plenty of punch, and maintains constant speed under load. The finish is excellent and all parts fit together snugly. This drill has just the right weight and size, and fits comfortably in your hand. The Panasonic kit comes with two 3.0 amp batteries so you always have one in the ready. My battery lasts a full day with heavy use.
I bought the Panasonic to replace a 12-V Makita. The Panasonic has more power at the same voltage (the 3 amp batteries). Small drill bits will not spin in the chuck!!! The electronic brake is also excellent, althought this can't be good for the brushes. No problems so far.
My only complaint is that the trigger needs to be more sensitive/responsive. It slowly increases RPM's as you depress it, and then goes right to full speed.
Overall, I highly recommend this drill for all general tasks. It will out-perform other 12V drills, and is just the right weight to carry around or for working overhead.
