DeWALT DC825 Impact Driver

Just a quick demo of my new DeWALT 18 volt impact driver with the 18V NiCad battery. I had a Craftsman 1 1/2 inch spade bit for this demo. The wood is a 4x4, which I think is treated lumber we had bought for our deck awhile back. I've been very impressed with the power of this drill. It's totally variable, not a 'two-speed' variable...meaning you can make it go very slow and then gradually faster. It's not the 'variable' type that's either sort of slow and then fast, nothing in between. Towards the bottom the hole got pretty clogged up with wood and I think it would have done a little better if I had pulled it back to clean the hole out at least once. Camera used for video is Panasonic LX5.

torque (impact) vs horsepower (regular drill)

@haus05 Tis true... I'm an apprentice electrician and I pissed myself when I saw an experienced worker on our site use a Makita impact driver to hole saw a piece of wood :3

@knurlgnar24 Yea I Agree Drills Drill.... Impacts Are Great For Screwing, Setting Lag Bolts, Fastening Pipes etc etc ... But For An Application As Demonstrated In This Video One Should Choose A Hammer Drill.... If I Was On A Jobsite & Saw Someone Drilling 1" Holes In Wood/ Pressure Treated Lumber I Would Laugh As Would 99% Of The Other Trades On Site... The 1 % Not Laughing Would Be The Guy Using An Impact Gun To Drill

@knurlgnar24 of course, you need to use special impact drill bits. but an impact driver is ideal for low rpm, high torque drills like the spade drill in the video. spade bits are also generally softer steel so you can get away with using standard bits. there's also no problem with "elongation", at least not in wood. Does the hole in the video look elongated to you?

If you drill large numbers of large diameter holes in wood with a normal drill, you will just kill your wrists.

@aseglkj I normally do not reply to rude posts, but you're misinforming people who may not understand how impact drivers work so I'll reply for their sake. Impact drivers tend to 'drill' an imprecise elongated hole and work much slower than a true drill. They can also cause dangerous bit breakage on hardened bits not designed for impact use. Keep in mind that you also need a special attachment to use round shank bits. A pro will tell you that the proper tool for drilling is a drill

@knurlgnar24 uh, actually, dumbass, they're perfect for drilling into wood, especially hardwood. drilling with an impact driver will reduce the strain on your wrist A LOT

I like it.

A good tool and a nice demo, but I want to mention (for people who may not already be aware) that a drill is better suited for this particular task. Impact tools are designed to reduce arm/wrist strain in high torque applications and to prevent cam-out. They excel at fastening but are not particularly useful for drilling.

Again, nice demo. It's interesting to see how this impact driver is capable of doing dual duty in a pinch.

i bought a set it came with the drill driver and the impact and 2 lithium ion batteries you cant beat them the batteries charge in 30 mins the drill driver it great lots of torque and the impact is awesome dewalt is the way to go!!

DeWalt big tool.
