EZARC Masonry 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

Really amazing durability

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.

These bits are solid. Easily drill through the toughest concrete or steel.

The best I ever used.

Used on plaster with metal lath and concrete. Kept its edge.

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

These masonry drill bits work well on concrete. All bits wear out sooner or later so for the money these are a fair deal for the dollar. Very good size for deep holes and works great with an impact drill at high speed. Comes in a nice case for storage . I would recommend this set .

I needed to drill into concrete. 1 inch. I have bought multiple other EZ Arc products with great success. Not so with these bits. I know they are low cost but….they are dull. I started out with the 3/8 equivalent bit. I used a 20v dewalt drill with full battery. I used a pattern of 15 seconds drilling and dip in water. After about 10 minutes of trying ….I think the bit drilled down 1/4 inch. I though I was losing my mind so I grabbed the 1/4 inch equivalent …same results. I looked at the bits closely. The cutting surfaces show minimal abrasion. The bits show little signs of being heated. I went and dug out an old Bosch bit. It sailed through the material in about 30-60 seconds. My opinion is that these bits came minimally sharpened. Again the bits that I sent back were barely scored so the metal must be tough. But you should not have to reshaped new bits.

I had an issue with a drill bit however the I believe the customer service is second to none with their prompt response in resolving the issue.
