11 Pcs Masonry Drill Bits Carbide Concrete Drill Bit Set for Stone Tile Brick Ceramic Glass Metal Sheet Plastic and Wood, Quick Change 6mm Hex Shank, Size 4mm,5mm,6mm,8mm,10mm,12mm with Case

Bought these drill bits to drill holes through acrylic sheets and plastic trims. Then attach with screws to wooden frames that I built. I drilled the holes with no problems and no cracks in the acrylic or plastic trim’s. The drill bits are strong and excellent quality also value for money. Recommend seller and product to everyone 👍 5⭐️ Stars.

I'm not often impressed to be honest, don't get me wrong I'm not a miserable dude, just prepared most of the time to be either flat out disappointed or barely satisfied...so to be impressed? Hallelujah something had not only met my lofty expectations, but surpassed them. Ok so your thinking, but dude, it just needs to put a hole in something....it has one metric.... hole-making. Long story short, used these with a non-impact driver/drill to put holes in my concrete floor in my home, and where standard Bosch masonry bits failed miserably, these things must ate through to create a neat hole, no cracks, no drifting, just a neat mound of dust and a hole. Simple and easy with just a bit of pressure. My tip, vary your speed during the drill, there's a joke in there but I'm not lowering myself to your standards, get your mind out of the gutter and add this set, which is strong, weighty, did NOT break, and comes in a plastic storage pack...to your basket. Inexpensive, does what it says on the tin, great fitment with the three teeth of most drill/drivers. I'm impressed. Thank the lord, I knew it would happen one day.

Good drill bit nice and sharp came in a decent container, but if you are too heavy handed they will bend which happened to one of mine. Apart from that they are good enough

Very good product first time using carbide bits more than pleased with the drill bit set.

Really good d drills went through re-I forced concrete posts easily, my old drills wouldn

Good quality. Do the job well.

The item arrived as predicted. Initially, I experienced some difficulty in actually opening the plastic container as, although there are arrows indicating the direction of movement of the lid, I needed to insert a blade just below the main headings before any sliding movement could be achieved. When opened, part of the case may be bent to more readily expose the heads of the variously sized drill bits available inside.Once I'd managed to open the case, accessibility was easy. To date, I have not had need to use any of the drill bits.All this is actually about opening the case! I still need the blade. The star rating relates only to this aspect.

One of the smaller drill bits broke immediately. All of the others have been fine
