BOSCH GT300 1/4inch Carbide Tipped Glass

Had a bath to shower remodel done and needed many holes drilled in porcelain tiles, but contractor's sub didn't have bits for anything but ceramic tile. Loaned the guy my diamond tipped bits, and they took forever to drill through the porcelain. General contractor came back and brought the sub his set of bits. Now, they didn't cut through the tiles like butter, but they did drill holes fairly easily. So impressed, I bought myself a set. These get the job done!!

I only used it once to drill into a bathroom shower ceramic tiles. It works well, but it's not like butter, like some reviews claim. You have to score the tile before you drill, or it will go sliding all over the place. It takes a little patience, but the grab bar is up.

These bits are much smaller than the image. The quality is average—a big disappointment.

Summary: Adding a few grab bars to dad's shower. I used a lot of products for this project, so including all related products in this review.Recommendation:1) When mounting grab bars, it's always easier if you can find the stud to attach to. In this vertical install, I decided to use a stud and Wing-Its anchors; partially because I wasn't sure I could hit both, and didn't want to put two fasteners vertically (on either the right or left only), but that would also position the bar in the shower a little too far in (towards the shower control).2) The WingIts requires a 3/4" hole through the mounting material. For tile, this can be especially challenging. I used the SHDIATOOL diamond 3/4" bit, with the DRILLAX adapter to get through the tile, and then used the 3/4" BOSCH bit to finish through the dry wall. Also used the BOSCH bits for the other small hole. Having the right tool for the job is the difference between project completion, and a messy, disaster.Related Products:Moen R8924P Home Care 24-Inch Concealed Screw Bath Safety Bathroom Grab Bar, Peened ~ $30Pros: Moen name, includes stainless screws.Cons: None.Conclusion: 5-starshttps://www.amazon.com/gp/product/B001EI0TJ4Structural Grab Bar WingIts, PK2 ~ $14Pros: Heavy duty, highly rated.Cons: Cost ($7/anchor).Conclusion: 4-stars (cost)https://www.amazon.com/gp/product/B004CCRJWOSHDIATOOL Diamond Core Drill Bits 3/4 Inch ~ $13Pros: Right tool for the job, looked brand new after drilling two holes (with proper technique, including cool water).Cons: None.Conclusion: 5-starshttps://www.amazon.com/gp/product/B07213KCN9Drilax Core Drill Bit Arbor Adapter ~ $15Pros: Allows SHDIATOOL bit to be used with drill (instead of angle grinder).Cons: Cost (a little expensive).Conclusion: 4-stars (cost)https://www.amazon.com/gp/product/B0737H7CMXBOSCH GT3000 Carbide Hammer Drill Bit Set ~ $25Pros: Cuts great; carrying case.Cons: None.Conclusion: 5-starshttps://www.amazon.com/gp/product/B001GNC8RS

These tile drill bits perform exactly as advertised. No slipping, clean holes and went through effortlessly. Worth every penny.

They drill well, only issue they break very easily. I ordered 2 and drilled 5 holes with each.

Used it to drill a few holes through tile in bathroom shower. Put down some duct tape first to prevent slipping. Perfect easy to drill holes

Product exactly as described. As mentioned in many reviews, was only able to drill 3-4 holes through porcelain tile before drill dulled, but hey…. It’s Porcelain!Recommend you buy one bit for each 3 holes you have to drill through porcelain tile!

Brocas de excelente calidad, lo tome en promocion y gane bastante, ya los he utilizado para diversos trabajos en losetas, ceramicos y da un corte perfecto

works well on ceramic, needed to put on stainless steel grid on kitchen backsplash. very hard ceramic tiles but bit worked well. need patience as it did take slow and easy process in order not to crack tiles.

Usamos a broca para perfurar porcelanato e foi ótima.

Voy a tratar de realizar la devolución. El producto se dañó y quedó inservible en el primer orificio de un mosaico del baño.

High quality product.
