Drilax Diamond Hole Saw Kit for Tile and Glass, 10 Pc Drill Bit Set 1/4 to 2 Inch with Guide, Ceramic Porcelain Granite Stone Core Bits for Drill, Circle Cutter for Faucet Drain Installation

good buy. Bit i used worked great to drill hole in a counter for soap dispenser. I was able to use the templet to position the bit and hold water for drilling hole. this gives you most any size you need for a little more than buying one bit. the holder / guild worked good and the zipper carry case is nice and not flimsy. i would buy it again if needed. I used to sided tape to hold guide to counter top and hold water in while drilling. it took maybe 30 seconds to go through 1/2" Corian counter top in a camper.( bits must be used with water ).

With a lot of doubt and very narrow expectation I bought this one. Basically I scoped to drill just 2 holes of the largest size and be done with it, if it fails. To my sweet surprise, this thing worked more than I expected. I was able to use almost all the drill bits for our bathroom renovation! Based on the first success, we even extended the tiles all the way to the ceiling. Because now we can easily drill holes for each purpose!! 1. I drilled holes into a 1/4 inch porcelain tiles, ceramic tiles 2. I had drill holes for the 1/2 inch water outlets, shower outlets, electrical conduits, screw holes for shelves 3. Which means, I had use same bit more than twice/thrice Im not a professional but here are few things I have observed. Things to remember 1. ALWAYS use water. Dry drilling is not healthy to the bit and causes a lot of dust and sparks. 2. Use the foam thats provided as a guide. Improves accuracy of the hole by a 1000% and reduces slippage! 3. Start slowly. Set your drill to its lowest speed and with very light pressure. Allow the bit to make scour marks on the tile first. Ofcourse hold the foam tighter!! 4. Drill - Stop - Clean - Continue. I always take the drill bit out, run it in a stream of water and then continue the drilling. This prevents "sludge" that forms with the water and tile dust from accumulating or thickening. What doesnt work 1. The drill bit spindle gets scarred by the chuck holder. Since there are no holding wedges on the spindle, you have to tighten the chuck and thus leave marks on it. 2. This is definitely 2 person job. You need one person to steady the drill (atleast initially) and another person to hold the foam and stream water on the drill bit Considering the fact the closest PRO version is more than double this price, and it worked for an entire reno project for me, I would say it served its purpose! But given the fact it still has the edge (read diamond bits), I think this is a great choice to buy for DIYers like me.

They drill fine, have tried on tiles and concrete with no issues, keep the water up to it..

I purchased in January 2021 for $44. I actually needed 3 of the sizes that this 1 kit came with. I went to several tile shops, supply houses and looked online and I found that price of just ONE of their bits was more than this set. I figured worst case scenario, I would burn them up, finish the job and pitch them in the trash! 2 years later and I have absolutely punished these bits and they haven’t slowed down a bit! I’ve used them on porcelain and ceramic tile, 2 granite countertops and the ultimate torture test was drilling through 3/4 granite tiles. I needed 4 inch round holes that kept cracking when trying to use a grinder. I decided to use these bits to drill multiple holes to make the 4” hole and it worked great! You can use the foam backing pad that holds the bits to CENTER it since the bit itself doesn’t have a centering bit. Get the hole started by holding the foam piece with one hand, fill it with water to keep the bit cool, then start the bit slowly with the other hand. I used a Dewalt battery drill and they worked great. I do keep them cool with water and low RPM’s while using them. I’ve even let a friend borrow them and they are still good. The ONLY CON: They are not deep enough to go all the way through a granite countertop. Bit is too shallow. So you can either start the top and go as far as possible then tap it out with a hammer. Or start the top and go as deep as possible then switch and approach from the bottom if you need to. For all tile including porcelain, just take your time and keep the bit wet and cool and they work and will last! Work great on tile backer board also! Definitely recommend them though!

Surprised that they really cut well. I was skeptical at this price. Don't know how long they'll last but the 1st couple of cuts went well.

Awesome bits and storage case. I was refurbishing an old outdoor table and in doing so I put new tile on its top and needed to drill a hole in one of the tiles for the tables umbrella to go through, they worked flawlessly! I have since used them when retiling my shower, again they worked flawlessly!

Love everything about this set and used it as soon as it came. It has everything a hole saw should have. Extremely sturdy and fast in cutting through pottery and glass. The assortment of sizes means I will never have to purchase any more diamond hold drill bits .. .ever!

First off, for the price, the bits were a good value. I got multiple sizes of diamond bit for less than $40 and they did work great for the first 2 holes in 3cm granite. 2 holes each were their max though, and that was with constantly drilling in water at a slow rate for around 30-45 seconds, vacuuming the hole (water and particles both), then rewatering and repeating until all the way through. The 2" hole bit held up better than the 1/4" bit in granite, but neither will be usable for a third hole which is a shame because I need to drill four 1/4" holes and not just two. I have since purchased a different brand 1/4" bit and it cut both of the other holes without issue and still has diamond abrasive material on the tip following the two holes. Those other bits were more expensive though so like I said in the title, you get what you pay for. Obviously if you are cutting through softer or thinner materials you'll get more holes cut with the bits. Note: These are not deep enough to cut through 3cm granite without having to cut from both the top and the bottom and ensuring that you keep the holes lined up. I had to cut from the top with the 2" hole saw, then realign and cut from the bottom to get all the way through. I knew that going in and am not downgrading the product based on that, just wanted to make sure everyone that reads the reviews understands that.

Excelente producto, puedo comentar que se me presento un problema, el monomando de lavabo que compre, tenía un diámetro de ensamble superior al que tenía mi lavabo, por lo que con el cortador hice más grande el orificio y me quedo excelente, mi lavabo es de cerámica

Having used a few brands of these bits before I decided to pay a little more for this set however they aren't well made with poor grip to your chosen drilling device. Onnfirstbuse under cooling conditions I wore the bit out before breaching 4mm of glass. Very disappointed.

Muy buena calidad y muy económicos.
