In addition, For me, these are as good as most, and I would say they are probably up to most. Because of the carbide cross tips, I can go through rock and concrete, wire mesh, and even rebar with them (but I have not tested it Even though there are problems with the clear plastic cases they come in, I like them anyway. There was a crack at the top of my piece, and the hanging hole is useless since the two halves don't grab enough to suspend even a little It's no big deal though, this case is just a bonus, so we don't lose a star. The shanks of the bits are deeply indented with a unique pattern that makes them easy to read The dimensions of the read size are If I want to locate a twist drill, for example, I hate to find the size had 'worn off' because it had just been etched or printed I do not have the capability of testing the metal, but the buzzed right through cement block and slid smoothly into my concrete slab, as if nothing happened. Once that is done, the bit still looks sharp and feels solid. It's hard to tell how long they will last, but so far I don't think they'll break. You might even be able to sharpen them if you're good at using a grinder. Concrete bits made by big name brands may last longer, for These bits will do the trick, and you get nine of them for less than half the price of two 6 inch long by 12 inch Considering that I'm not a contractor who uses them every day, it would be nice to have a better choice of sizes when I need them. All the tips wear out, and they are all Tungsten Carbide, so I can get the kit with 5 times as many for about the same price.

+ Carbide tips break through rocks, wire mesh, and structural steel. Keeping them all together in one case is handy, since it is small and neat. The size of the bit is stamped on the shank of an SDS Plus. Pro

Cons

The case was broken when it arrived. Please note There is no way to hang the case.

I sometimes need to bore a hole into a concrete foundation or a brick if I'm working around the house. The first step to mounting a masonry retention bolt is drilling a hole to fit. To do this, I have found an SDS Chucked Hammer Drill to be most effective. SDS stands for "Slotted Drive System" which holds special bits that have these slots. These bits come in 7 diameters the DUDUA TC Cross Tip bits have Tungsten Carbide (TC)X tips. There are a total of 30 pieces two each 6mm(1/4") and a total of 5mm(3/16") Eight (4mm) is 5/16", ten (3/8") is 3/8", twelve (1/2") is half, fourteen (nineteenth), and sixteen (4mm) is 5/8". The fluted drilling depth for each tool is about 90mm, and they are all about 160mm long (*6 inches). In a plastic tube with a twist cap, they are safe, compact, and easy to store. Take a look at the 2 doubled bit sizes together in figure 1 In the second picture, the TC crosstips can be seen when the bit tips are constructed. There is a size stamp on each shank and the bits are made with carbon steel bits to withstand the pounding that comes from a hammer impact drill Compared to a regular drill bit, a regular drill bit is made of a different hardened steel that would fracture instantly, hence the different color. A SDS Shank can be used with an SDS Hammer Drill (Picture 3) in order to prevent the bit from rotating inside HAMMER drills use repeated blows parallel to the bit to slam the drill bit into the material being drilled, and rotation allows them to change bits quickly. SDS shanks are identical, and they all have the same structure, so bit changes are made quickly. The rotation direction of an IMPACT drill is insufficient for these bits, which can only be achieved in axial rotation where it is appropriate. AVOID RISKING your eyes by always wearing eye protection! When high speed rotary tools turn, they will fling pieces of debris, and this debris can cause If you breathe the fine dust created by the concrete drilling, you could suffer silicosis lung problems. Wear a respirator or sturdy dust mask when drilling concrete. First! This DUDUA 9 Piece Carbon Steel Hammer Drill Bit Set, SDS Carbide Tipped Drill Set is a great choice. I found the bits to be very strong, well made, and I expect they will last a long time. Despite the high price, they provide I hope you found the information and my review helpful.

The SDS drill if you have one will work very well. These are as good as most I have used, but the price will make you buy them again. Concrete is hard, they don't last forever, and the sharper the bit, the better the cutting. Buying more of these.
Great value for the money.
