Good product have used twice and performed well

Yes this is a good item to have if you got a how much drill dick and break cement you got all the bits you in my need right there I was happy I had it when I had to make three holes in front of my house so I can put three poles so people can stop parking on my damn sidewalk and breaking the damn water pipes that are under it it cost me a lot of money to keep fixing that damn thing so I got frustrated already and I seen this and I bought the tool that I needed for it and it came out perfect believe me I recommend this item my nephew just got one for himself and he loves it too he already broke some cement in his house so he can redo the porch in the back and he said work great for him too so people I do recommend this to anybody that needs this then has the tool that uses these you have it right there you can never lose it because you have them all in one spot that's another thing why I liked it too it kept it nice and organized 👍🏻👍🏻👍🏻👍🏻👍🏻

I didn't catch it in the reviews when I ordered the set, but realized it's metric sizes for the drill bits, so don't expect them to make proper sized holes for ## inch sized concrete anchors. You'll want proper sized bits for anchor holes.If you need a set of bits that you can just outright beat the snot out of for demolition use, this set works great. The bits seem well made, and have held an edge so far with extensive use.

Nice companion accessories for my hammer drill.

My first order came and upon opening it discovered they had obviously been used with one bit being very chewed up and damaged... Annoying, but Amazon made getting a replacement easy.These are great for the price, but don't expect to use them daily without wear and tear. The chewed up bit from the used set I got first was probably from someone who thought they could drill a 5/8" hole in concrete without a hammer drill and melted the bit. I would have stepped it up and started with a smaller bit first, but those looked untouched. Don't expect to abuse these and have them last!

Really nice bits for the money. Case is decent, though it doesn't hold all the bits super well and they were all over the place upon arrival (not a big deal really). That is just the bonus piece though so it is really serviceable enough.All of the bits look finely machined and professional, and came lightly oiled as they should be. I can't really speak to the durability yet as I haven't got to really beat on them, but they certainly look and feel solid enough for a home-gamer like me.

After seeing the price for individual bits are in the stores, I had a difficult time spending $20 to $30 for one bit. Once I saw reviews that indicated the would last more than just one use, decided to give them a try. I have only used a coupe of them so far. However, they handled concrete with ease and about an hour trying to break through stone. There was next to no damage to the bit, and showed no signs of fading. Just for the fact I made it through one project, and know they can be reused they are more than worth the price.

I needed the chisels but this kit was cheap so I bought it with the bits.The chisel has already done enough work that I would call it worth it for the low cost of this set.The bits are another matter. I drilled probably 8 holes with one bit and it’s already worn out. It was in high density concrete but still. Again this is an inexpensive set. If you just need it to get through a project it’ll do the trick. If you need long lasting hammer drill bits, look elsewhere.
