ZELCAN Chisel Set with SDS Plus Shanks, 6pc Masonry Concrete Drill Bit Set, Tile Grooving Scraping Flat Point Scaling Chisels 40Cr Steel Rotary Hammer Drill Tool Kit SDS Plus Bits for Home Improvement

totally awesome, works with my equipment, saved a bunch of money.

Muchas gracias

Muy buen producto

The flat bits worked well for grooving buried rock and concrete. The pointed bit got stuck when driven straight in too deep and had to be extracted by using other bits to break it free. Probably best not to go deeper than the point. Move and repeat in a line. Wear a mask and hearing protection.

Bits fit the drill well and do as they should

Thank you

Very tough bits, work well in my SDS. Lock in very tightly and our hard enough to do the job. Used in conditions that are not always ideal and have taken on a little corrosion. Extra care needed to halt corrosion.

I was in a hardware store looking at sds+ bits to see if there was something better to use for scraping up tile in a remodel I am doing. The last bathroom did not go as easily as I thought it would and I expect that was due to using chisels that were too wide and/or too thick. I saw the bosch bulldog tile scraper and figure that had to help with its nice long thin-ish, offset and angled profile. I didn't want to pay the asking price for a tool I might never use again ( and might not work any better than the others did ). That brought me to amazon to look for a cheaper alternative, and get a variety of bits to try for less money. I chose this vendor, even though there were cheaper alternatives, because their pictures seemed to show the same sort of profile I saw on the bosch. I'm disappointed now that I see them. There is an angle but it is so slight it is hard to be sure. Its only about < 2mm difference from center of the bit when measured at the tip of the chisel. I had to lay it on a flat surface and then I could see a very slight rise or drop depending what side I have the bit laid on. So the bend is there but I'm not sure its enough to make any helpful difference. It was even harder to see if there was any offset. It certainly doesn't look like it. It is clearly not as angled or offset as portrayed in the pictures. Since this one bit is the most important one to me for an upcoming project, I am going to return this set and buy the bulldog bit.That small gripe aside there is a good variety and they seem durable. The metal is not perfect. As others have mentioned there is some texture to them. I'm not sure I would say pits. More like a subtle grain. Since I bought them to destroy things with them I was not terribly concerned about surface imperfections. They came with a decent edge on all the bits. If I had paid $50 per bit I would expect better finish. If I were just looking for a cheap variety to play with I would probably keep this set, but I'm not sure it is any better or different than the large selection of other sets being sold on amazon for less.
