Rated 3.4 out of 5 by 42 reviewers.
Rated 1.0 out of 5.0 by Used twice, stops working, not covered because I don't have a receipt. Used twice for hammer drilling 3/8" anchors, stops working, not covered because I don't have a receipt. Probably a hung brush and I will fix it if I can. July 24, 2015
Rated 4.0 out of 5.0 by Decent Drill / hammer drill I used this Makita 5/8 Hammer Drill too anchor bolt a dog pen to a concrete slab. Had no problems with 1/2 holes. The nice thing about this drill is it has a dual mode. Nice power to handle middle of the road work. The cost is reasonable for what you get. If your doing a lot of work with concrete. Be sure to clean out the concrete dust, with a burst of air pressure. It will last much longer if you do. It's not a Hilti but for around the house it's a nice tool. December 9, 2010
Rated 4.0 out of 5.0 by OK for the homeowner It did not come close to the Milwaukie ( sorry about the spelling) that my wife got in the divorce but it did OK for small jobs. Had a hard time getting the bit to stay secured in the chuck. Had to keep getting out the key and tightening up the chuck. If you get it on sale and only need a hammer drill once in a while, it will work for you. If you need to drill into "old" concrete that has cured for 10+ years then you may have a problem. And yes, in case you did not know, concrete continues to cure for many years. Hope this helps. September 2, 2014
Rated 3.0 out of 5.0 by Awful chuck and chuck key I loved this drill when I first got it. Tons of power, worked well the first day I had it. The chuck and chuck key started getting rounded to the point that it was almost unusable after a month. Wound up returning it July 13, 2013
Rated 1.0 out of 5.0 by hagerstown md homedepot when buying a drill that days 5/8 chuck you would think that you could get a half inch drill bit in it but all of these at home depot have a 3/8 opening NOT 5/8 not correct information what a let down had to drive back and buy another hammer drill for 300$ because false information May 19, 2015
Rated 5.0 out of 5.0 by Made in The USA! Great Value! I had bought a larger "Red" hammer drill, thinking it's bigger motor (in Amps) meant more power and better performance, and I was wrong. I was really surprised to see that the Makita was made (at least assembled) in America. For a small, fairly lightweight drill, it packs quite a bit of power. I love the keyed chuck, because it grips bits much tighter. The 360-degree rotatable handle and depth rod come in handy for doing multiple anchors. Sure beats taping my hammer bits. I also love that the forward/reverse switch actually moves the brushes, as opposed to just changing a gear setting. This means you get full power in reverse. One of the other reviewers said the tool wasn't as advertised, because it's a 1/2" chuck, not a 5/8". When dealing with hammer drills, or larger rotary hammers, the "size" refers to capacity (hole size), not chuck size. What that means is this has about 25% larger drilling capacity vs. a 1/2" hammer drill. Bottom line, this will not twist your arm off with power, but it has way more than enough power. When a smaller motor can drill a larger hole (as compared to the red or yellow hammer drills that cost $99 or more), that goes to show you that the tool itself is stronger and better-built. It doesn't have to rely on a bigger motor to get the job done. I recommend this drill to anyone I know who is looking for a basic electric drill, even if they don't think they need a hammer. It weighs less than the 3/8" drills on the market, performs better, and gives the added benefit of being able to drill into concrete/brick/block! September 19, 2012
Rated 4.0 out of 5.0 by I love it, although not 100% as advertised. Made in USA! I absolutely love this drill. Admittedly, I used it on one occasion, to drill a 1/2" diameter hole through a solid brick wall, and then to drill multiple (maybe 8 or 9) 3/8" diameter pilot holes for masonry screws. With new bits, the drill cut through the wall in 10 seconds or less. This drill is VERY powerful for the money. It's 6 amps. To put that in perspective, I have a Skil hammer drill that I got as a hand-me-down from my grandfather. The thing is a workhorse, and it's only 3.6 amps. I also have a DeWalt that is significantly outpowered by this drill. It looks, feels, and even sounds like a high quality, professional grade tool. The cord is thick and has plenty of length, although plan on using an extension cord if you're not five feet from an outlet. The extra handle is a nice feature and provides some much-needed extra leverage. I spent a little extra for a Makita because they are one of the only (if not the only) power tool company that still at least assembles their tools here in the USA. I like supporting our economy when I can, and I thank Makita for making that possible. With my unfailing patriotism, I really want to like this tool, so I may be a little biased. It would not be fair, however, for me to not point out a couple of flaws. First of all, the chuck on my drill is NOT 5/8", it is 1/2". That's not a HUGE concern, because I don't own any bits that are larger than a half inch at the base anyway. Even my 1 inch diameter masonry bit can be used in a half inch chuck. Also, it is a keyed chuck (which I preferred in this instance), but I can see how the key would be easy to round off. Tighten with caution. Thirdly, there may come as no surprise, but there is no brake on this drill, so you may want to reconsider if you find yourself about to use it on projects that require any level of delicacy. Finally, this drill does not come with a case. Minor setback, but a setback nonetheless. These downsides for me are minor and I hesitated to even take away one star. When I purchased this drill, I was looking for a corded (so I don't have to deal with charging batteries), keyed-chuck (no loose bits), American-made, semi-professional grade hammer drill. I got exactly what I wanted. July 24, 2012
Rated 1.0 out of 5.0 by Not a good investment. I bought my drill 2 years ago and used it for drilling 3/16th holes in concrete. I drilled about 100 holes and the brushes and armature burned out. Upon examination the pinion gear was near failure as well. When the drill was working it did a great job. But to fail this badly after a minimum of use is unacceptable, even for a product at this price point. In my opinion this drill is under designed for job. September 5, 2013
