TR Industrial TR89305 Electric Jack Hammer for Demolition, 60-Joules, ETL Listed

I had a brick patio with a thick concrete slab under it. The weeds had come up through the bricks, and many of them were loose. Rather than repairing the patio, I decided to remove it. This turned out to be a huge undertaking. I tried removing the bricks with a hammer and chisel and soon learned this would take forever. I considered renting an electric jackhammer, but it was going to be at least $75 a day. This job would take several days to complete, and I didn't want to feel like I had to rush and wear myself out in the process. I read the reviews for several different jackhammers, and decided to order the TR Industrial TR89305. I'm glad I did. This tool made quick work of removing the bricks. I learned that using the 1" chisel and working from the end of each break allowed me to remove them without breaking many. A friend was going to reuse the bricks. Once they were gone, I began breaking up the slab. The slab was 14" thick on the outer edge. This jackhammer would break up the concrete a few inches down. I had to slab off some and go back for another bite. I tried the pointed bit, but it tended to get stuck. I used the 1" wide chisel for almost all of the job. I applied silicone grease to the bit before inserting it into the jackhammer. At first, the bit bit would stick in the chuck of the jackhamner when I lifted it from the concrete. I would have to raise the jackhammer and use it to tap the bit into place before breaking more concrete. Over time, the bit loosened up and didn't cause this problem. I worked in a line about 3" from the edge. I would hammer some and move to another spot. I would have to go over each place a few times before the slab would break. As I got farther from the edge, the concrete became thinner and much easier to break up. On the last day of the job, I figured out that by locking the trigger in the on position, I could guide the jackhammer with my right hand without having to squeeze the handgrip tight. I wish I had figured this out sooner because the vibration from the tool causes numbness and some pain. The numbness goes away over time, but not gripping the tool so tight is much better for your hands. The jackhammer performed well. It comes with oil that you must add before using the tool. I bought a jug of Rotella 15-40w synthetic blend oil. After using the tool for about 30 hours, I did have to add some oil. Some oil seepage by the seal is common in this type of tool, and I don't think this is a big problem. I am very happy with how the jackhammer performed.

Edit: I've used this on and off for about a month for the pool I'm installing and it just keeps going. To think I almost rented a hammer from a local too rental that would have cost more for just a week! The bait here is tremendous and it's a solid machine. Upgraded my review to a 5 Star I saw the good and the bad reviews with this and gave it a shot. It did the job great, worked as expected. Broke up concrete between 4-8 inches fairly easily. I didn't have any problems with the jack hammer itself. Weight was good. I can't really say anything bad about it except I've never used anything else to know if something could be better. I used it for about a week before making this review.

I will start off by saying, when I first saw this tool, I was kind of skeptical of its quality and performance. However, I took a chance and purchased it, since my reasoning was if it lasted long enough to complete the job, then I would have gotten my money's worth. Once it arrived I was surprised by its weight and relatively beefy construction. Even the chisel bits that were included were properly hardened and very durable. I have continued to use the thing on multiple jobs with no issue. I rate 4 stars for a few reasons: 1. I have no other experience with electric breakers of the same size made by Bosch, Makita DeWalt etc. so I cannot say its excellent. 2. The screws do loosen so its good practice to use some threadlocking compound on them. 3. The trigger is rather stiff to depress. ( all are minor complaints ) . One thing to remember here too is using the right tool for the job. This piece of equipment works very well on thinner concrete and lower strength mixes, It struggled with a 12 inch thick 4k psi foundation that I had to enlarge a hole in, but the job did get finished. All in all, I had good luck with this machine so far , and I think its worth the money.

At first, I was doubtful. Then I decided to use it to demolish a driveway that had 12" thick concrete slabs... It took a few days, but this breaker hammer got the job done just fine. Just keep an eye for the oil. You must refill it every now and then. I used rotella 15w40 for diesel trucks. No issues so far. What is most impressive is that I tried using a Hilti 3000 breaker (top of the line $3000 hammer) alongside and compared them. The difference in performance was minimal. Yes, the Hilti is a little more powerful, bigger and easier to grab onto, but other than that, there was little difference in performance. Not to justify the abismal price difference between them. I think that says it all... I would love for it to have different handle types because sometimes it is hard to keep posture ( it's heavy). All in all, awesome breaker hammer to tackle anything from medium to heavy jobs. We will see how long it lasts, but so far it looks solid and it has paid over itself a couple if times now.

We are building a new deck, and had a 8x20 concrete slab about 8-12" thick. After the local rental tool place quoted me $329 for 48 hours, and a couple of contractors wanted $1000+ to do it for me, I realized quickly I needed a jackhammer. After some research and some wise guy funny comments from my friends, my jack hammer arrived and we went to work. This thing is a beast, it busted up everything we threw at it, we moved over 4.5 tons of concrete from my backyard to our dumpster, without any issue. No jams, no stoppage, just huge breaking power, and the concrete didn't stand a chance. If you need a jack hammer, I highly recommend it. Comes with a nice case, oil, two big strong bits for it, and a long cord. For the price, it cannot be beat. Thank you TR Industrial for this fantastic product.

Todo muy bien

Package arrived on time, added the oil which was supplied in the case and was ready to go. I used the hammer to break up old concrete poured down at the waterfront at our cottage. The unit is powerful and works well. Time will tell regarding longevity but after first use ( about 4 hrs steady use) very impressed

EXCELENTE PRODUCTO, MUY POTENTE, PERO AHORA NECESITO ADQUIRIR LAS PUNTAS PARA ESTE EQUIPO, CUALES SON LAS QUE NECESITO PARA ESTE EQUIPO? MUCHAS GRACIAS

This is a beast! With the attachment it is over 40 lbs but the handle allows you to stabilize it well. Cuts through old concrete and limestone rock like butter. Made short work of a set of old steps - now I'm looking for things to jackhammer! A well made piece of equipment.
