Maybe I'm spoiled with the Bad Dog masonry drill bits I've been using for years, but these bits just couldn't cut it (pun intended). To be transparent I only tried using these for plaster and concrete (not glass or tile) so maybe they will work better on those substrates.When trying to drill plaster I found the bits would make a dimple and then seem to just spin in place without making any decent progress. One thing you don't want to do with old plaster walls is force a bit through it.. or use a hammer drill.. that will just loosen or break loose old plaster from the old lathe that is probably not nearly as well attached as it was 100 years ago :)So I gave up on the plaster and tried one of these in my concrete basement floor.. just to see. Well, again, they seemed to start ok and made a small dimple but the progress was terribly slow. Using a light hammer drill driver helped somewhat but again, it was slow going.I've drilled into concrete and plaster before with other bits so I have a pretty reasonable expectation of performance and speed and these definitely come out on the slower side. On a positive note, the tips held their shape, did not chip, and did not show appreciable wear after my testing so maybe I got a bad batch.. or more likely, they are not shaped aggressively as that would really test the material and weld of the bits.I still have them lying around but they aren't my go-to bits for anything. But, for the price point, I may have been expecting too much.. my other go-to bits cost about 15x as much for the same number of bits.

Punte molto valide. Molto bene su diversi materiali. Gress porcellanato forato con minimo sforzo (importante tenerle refrigerate a modo). Non eterne ma lavorano bene e durano. Ne ho subito comprato un secondo set di scorta per timore di non trovarle più quando il primo sarà andato. Consiglio senza esitazione.

Low / no durability for any drilling other than wood or concrete block. Stone, glass, tile, clay, etc. is unfazed by these worthless drill bits.

I’ve only use them once, they worked very well on wood. My next job will be on concrete, I’ll see how well they hold up on that.

I bought these for one thing, specifically to bore holes in brick and concrete. I’ve had a lot of issues with cheap bits, and the cheaper bits don’t work at all. I was pleasantly surprised with these bits. They worked much better than similarly priced bits.The only caveat is that these are specialized bits. The work well with hard material, but not metal. These are not all-around bits; they are for a specific propose. I don’t have an issue with that, as I understand the tool has to fit the job sometimes, but some people may want a more universal bit. I don't care much about this as it's almost impossible to find an all-around bit that works on masonry, so I didn't downgrade my review for this reason.One very nice feature is the hex shank quick attachment. That is extremely useful, and a great feature to use the bits. It can be a pain to change bits, and that makes it much easier.

SUMMARY• I originally got these bits to bore mounting holes in the concrete-foundation of my house — having experienced serious problems in the past with the cheap, ‘garden-variety’ masonry bits I used in the past. The need for those holes temporarily went away, however, so I evaluated the bits via a prospectively more challenging task: boring a ½ inch hole in the bottom of a glass jar using the largest bit in this set — ½” of course. With considerable care and water cooling/lubrication, I succeeded.• Moreover, the inside of the hole was smooth enough to plug with a rubber stopper and experience no leakage when the jar was filled with water. The tungsten carbide cutting surfaces showed little sign of wear.• Bottom line: given that the glass was at least as hard as most concrete, these results suggest that the bits are adequately hard and symmetrical to make good holes in masonry.TESTS AND RESULTS1. I first filled the bottom of a 10 oz jar with water, set it on a piece of wood inside a water-tight pan resting on the table of a drill press, and positioned the bit of the ½” bit on the bottom of the jar. See the first photo.2. I then bored at the manufacturer’s minimum suggested speed of approximately 800 RPM with very light pressure. After a few minutes (the process was slow) the bit penetrated the glass and water started flowing out into the pan. Therefore, I filled the pan with water adequate to maintain a water level of approximately ¼” to 3/8” in the jar — for cooling and lubrication.3. I finished boring through. See the second photo.4. I inspected the hole. Looks fairly good. See the third photo.5. To evaluate the smoothness of the hole, I filled the jar with water, plugged the hole snugly with a rubber stopper, and checked for leaks out the bottom. No leaks appeared. See the fourth photo.6. Finally, I checked the ½” bit for wear, both visually and with my finger. No significant loss of sharpness was apparent. See the 5th photo. (Note that these bits have FOUR carbide cutting edges — not two, as in cheap masonry bits.)DISCUSSIONGiven the hardness and breakability of glass, the adequate smoothness of the bored hole suggests a quality product (though similar results might be difficult to achieve in GLASS with a hand-held drill). Moreover, the Mohs hardness of the jar’s soda-lime glass — 6 to 7 — compares practically to the Mohs hardness of concrete — 5 to 7 (6 to 7 for HARDENED concrete, which presumably is not used in residential construction).Overall I’m favorably-enough impressed with these bits to give them a 5-star rating.

For many years, I have used my Tapcon concrete drill bit tool set for attaching wood to concrete block, and have been fairly satisfied. This Lytool masonry bit set is a different creature, and I mean that in a good way.In addition to basic grunt concrete drilling, these bits are designed for higher applications like stone (granite, marble, etc.) along with tile, and even glass. The instruction sheet gives good detail on using the bits with various materials, including RPM and whether or not to use water.I tested a couple of the bits out on an old scrap tile, and they did a good job. There are ten total bits with seven sizes, so this should cover most of your applications. Nice value!
