ENEACRO1-1/4 Inch SDS-Plus 13 Amp Heavy Duty Rotary Hammer Drill, Safety Clutch 4 Functions with Vibration Control Including Grease, Chisels and Drill Bits with Case

Edit [11/4/19]: Stiill going great! Used the 3" chisel to remove an old mortar shower pan and wall surround done in ugly old tile. Then, after cutting large rectangular openings in the slab underneath to get at the old cast iron drains needing replacement, used the Eneacro with narrow bits to break the concrete into manageable sized pieces. SO glad I bought this! Unfortunately, I'm now out of grease, and although the hammer is still working, no one from Eneacro has yet responded to my question of what grease to use! Hellooo!I bought this just over a month ago, and the hammer function just stopped working. I was prepared to be upset, but then I thought even though I haven't used it as many hours as they said before it would require adding grease, I would try doing that. I squeezed a little more than half the tube provided into the hole on the top (nice of them to include the grease and the tool to remove the cap). Then I ran the drill without attempting to hammer or drill anything for about thirty seconds. When I tried hammering again, the chisel just vibrated slightly, but within a few seconds, the old sound of the powerful hammer came back and the chisel went to work again!I know the company has someone read these reviews, so I hope they will respond with information about what grease to use when I run out, which I will be doing sooner than I thought. I am so relieved that the lack of grease was why the hammer stopped working, because I have done so much with this tool in the month I've had it.First, I used it to drill holes in CMU's (cinder block) to anchor furring strips with Tapcon screws (2x3's on edge to accommodate 2" polyisocyanurate insulation board). I bought a Bosch 3/16" SDS-Plus bit to pilot the screws. SO much faster than my 18-year-old Makita hammer drill that had begun to scream at me.Then, I used it to chip off some uneven concrete. I had to be careful, because it wanted to take away more material than I needed to get rid of. I ordered a 3"x10" straight chisel from another manufacturer so that I could take up glued down linoleum flooring quickly. I haven't done that job yet, but I also knew the wider blade would provide more control in chipping away high spots in concrete.After that, I used the rotary hammer to put multiple 3/16" pilot holes for Tapcon screws to anchor pressure treated floor plates over 30-year-old concrete. This was the kind of task that had likely killed my hammer drill over the years as well as taking a huge amount of time to drill each hole. Thus, this was the true test of the rotary hammer that I bought to replace the Makita. What a dream! The ENEACRO had each hole to full depth almost instantly, and since it was so fast, the bit didn't get hot the way the bits in the Makita had. So these bits should last much longer because they stay relatively cool.Next, I used that new chisel to make digging a trench though hardened dirt and sandstone rocks to lay a drain pipe to carry water away from my foundation. Wow! Made the job much easier than it had been using a shovel and gave me far more control than a pick would have provided in breaking up the soil just where I wanted the trench. A narrower chisel would have just buried itself and I would have spent all my time pulling the chisel back out of the hole, but this one was perfect. Any wider chisel in this soil, and I would have been better off with a full-sized SDS-Max demolition hammer, which was good, because I couldn't find a wider chisel in SDS-Plus.After that, I used both the narrow chisel that came with the rotary hammer and the 3" one I bought separately to break up 5 1/2 CMU's that had been solid grouted with concrete, rather than ordinary mortar. Several had rebar set into them, so I also used my 12" diamond blade concrete saw. The hammer allowed me to trim the CMU away from the poured concrete that was placed behind the blocks without gouging it, which was my goal. The saw only cuts about 4" deep, and I needed to go 8", so the chisel was indispensable. It was at the end of this job that the hammer function stopped working as well as it had, and I thought it was maybe just that the machine was hot. The fix was as described in my first paragraph above.Most recently, I made a 4" round hole in ungrouted CMU to run a dryer vent through the wall. The smaller chisel did an almost perfect job of it, so I only had a tiny bit of hand chiseling to make the hole fit the 4" duct almost perfectly, with very little room for caulk! I haven't done the outside hole yet (It's raining out there!), just put a small hole in the center of where the 4" hole needs to be from the inside, making it easy to locate the hole on the outside when it stops raining.If you have suffered from the inadequacies of even a heavy-duty hammer drill for years, as I have, do yourself a big favor and step up to the ENEACRO rotary hammer. It's a terrific bargain in a powerful tool!

I'm amazed how quickly it drills through 6" concrete. The main reason for purchasing it is to break through concrete. It worked better by drilling holes then chipping it out

Bought this tool to take out a stone walkway. It made a hard job easier. I added grease after about 3 hours use so you might want to check more frequently than the book tells you. I was satisfied with this tool...it did what I bought it to do.

This rotary hammer made short work of inch-think mortar plus the tile on top and wall tile for a bathroom renovation. I researched multiple sites and multiple manufacturers, plus the different types of bits, and wanted to hit the right price point for an adaptable solution. SDS-Plus bits are widely available, and this hammer had the all-metal motor casing, 13 amps of power, and other desirable features. The price could not be beat for the features.I ordered an angled wide blade separately for stripping off the wall tile, and used the flat blade bit that comes with this hammer for the mortar and floor tile. The narrow point bit was not as effective for this project, but I expect it will be for the chimney I need to take down.The only big question was the lubrication. It comes with a decent size tube for the grease pot, but you also need to lube the bit shanks similar to oiling an air nail gun. After extensive research and a bunch of YouTube videos, I ordered Makita's Hammer Bit Grease. Very easy to use and holds up under steady use. You need to add just a small amount of grease for each hour of steady use, and the 2.08 ounce size will last a long while. This grease should also be good for the grease pot.The air flow in the hammer is very good, but the metal housing still gets hot. I can't imagine a plastic housing holding up for long. A stiff bristle brush cleaned off any dust that accumulated. I didn't need the rubber dust protector that comes with the gun, which is more for drilling applications.The hammer is easy to hold and to apply pressure. It would be heavy for above-the-waist hammering more than a few minutes, but then it would count as a workout :). My favorite feature is the front handle. Twist one way to loosen, adjust the position, then twist the other way to lock down. OMG, what a time and strain saver! You can get the perfect hand grip without putting the gun down, and it's easy to shift from a right-hand to a left-hand orientation.The carrying case holds everything easily, although it did come with a couple cracks in it from shipping. No functional issues with the case, and it has metal latches and a heavy duty handle. I wouldn't throw it in the back of a truck, but it will carry the hammer and accessories and hold up under respectful use.I am thrilled to have added this powerful time saver to my workshop, and I'm looking forward to using it on the chimney takedown and other projects.

Got here in a timely manner, tool was good as expected.
