EZARCMasonry Drill Bit Set, Concrete Drill Bit Set with Hex Shank for Brick/Cement/Tile/Block/Plastic/Glass/Wood/Metal, Carbide Drill Bit Tip 5/32"-3/8", 5PCS

I needed a set of drills that would go thru wall tile (Shower Stall) and I needed to be able to go from small to large size in a fashion that my 4 year old could make the change and I could keep one hand on the pieces being drilled. Well these 1/4” Quick Change shafted bits are perfect.I showed my 4 year old the three bits in the order I needed them ‘A’, ‘B’ and ‘C’ and how to change them out - I held the piece, called out the bit I needed and was handed the drill with the proper bit in place - no tightening needed - they were seated in the 1/4” socket and I drilled the three holes getting to the largest and then I put in the anchors and we proceeded to the next hole. As she would say “Easy Peasy”.Of course the drills are gritted perfectly to handle ceramic tiles and grout- I did not have any chip out and the pressure needed was about what I use on wood - I never have done a PSI test for wood or tile (sorry).Overall, I liked these so much that I bought an entire set of wood bits with a 1/4” shank - so my helper can continue providing those extra hands when needed.Be safe

I finally had the chance to use my new drill bits. This time I made sure I bought tungsten carbide bits. I broke one of the bits from my other new set. They may have been titanium. I broke that bit trying to drill through a steel plate which was the backing of a security camera. It snapped in half. I tried 3 other bits and they all just sat there spinning but no hole.I got a new camera so here we go again. I set everything up the same way with the plate in my vice. The 1/4" hex base meant the bit will not slip in my drill. Started out drilling and within about 4-5 seconds I was through the steel. I drilled the other two holes just as easy. I was so impressed I actually wrote this review.Finally I have a nice set of drill bits that can drill through anything.

I liked the quality

Each Drill Bit made perfect sized holes for anchors & screw bolts into my Brick Porch Walls. Bricks were solidly made & laid for a 3ft wall around porch & 3 columns supporting roof. I drilled holes for Tarping the openings on the porch for winter weather so as not to get snow, rain & wind on my porch. Needed a bunch holes in the bricks to tie down tarp grommets & hang a few 14 in Weather Temp Devices. All holes Drilled were smoothly done just like drilling wood. Drill Bits were no torn up & looked exactly new after making some 20 holes into Solid Brick. I have other masonry drill bits & found these to be my go to Mason Bits. These Bits will hold their own!

Works perfectly fine in different surfaces. Good quality.

These drills will drill steel and even stainless steel (with water cooling) and then into concrete. I am very happy with them.

They seem to last and actually work on all materials listed

I cannot complain. Easily drilled clean holes through carbon fiber hood, which is awesome because you only get one shot at that. My wife actually drilled too deep into the brick mortar with her project while using these bits.
