Selected User Reviews For CooPee 17pcs SDS Rotary Hammer Drill Bits Chisel Bits Hole Tool Set Drilling Bricks, Concrete, Masonry, Wall, Stone
So far, I have only used a 5/8" bit, and it has proved to be a great tool. The machine continues to work well after about 50 holes in 4 1/2" concrete. This bit is not as sharp as the unused bits, but it wears very little. The bit has been kept from overheating by dipping it in a bucket of water for about 10 seconds each after each hole.
All the pieces fell out of the sealed box when I opened it up. After installing them back in the case, I moved them all to a new location, only to find they fell out again. The case for this equipment is useless everything in it is just thrown in a bag, as they do not remain in place within the case, and there is no labeling to indicate where the various parts belong. I have no idea how well or how long the bits will last, since I haven't used any of them, and I couldn't get past the fact that they kept falling out when I opened the case. As I see it, it's essential that the bits remain in place and are.
There were all the parts from the blue box outside of the blue box when it arrived. There is an oily film on the bits to protect them from rusting and a very thin coating on their tips. Thus far, I have only used a few drill bits and they all performed well in an STS.
When it is used for self-employment, or not as a form of forced labor, it is quite useful. There are some weaknesses in the steel used, including its lack of strength and durability. If you're looking for a value for the money, you can't do better.
It has a good price for everything it offers.
what I was supposed to do.
This is a nice set, it's.
Getting the most for my.
