3-1/2" Wet Diamond Core Bit for Concrete & Masonry, 1-1/4"-7 Arbor

I recently used the 4" Wet Drill Core Bit for a demanding concrete project, and it exceeded my expectations. Designed specifically for wet drilling, this bit offers a 10mm segment height and a 14" drilling depth, making it perfect for tackling tough concrete and hard masonry surfaces. The core bit provides smooth and consistent drilling even in the hardest materials. It cuts through concrete and masonry with ease, delivering precise, clean cuts every time. The 10mm segment height allows for enhanced durability, which means this bit will last through multiple tough jobs without wearing down quickly. The overall build quality is impressive. The bit is well-balanced and solidly constructed. Its 1-1/4"-7 Arbor fits perfectly onto the rig without any wobbling, ensuring stability during operation, which is crucial for accurate drilling. Using it in a wet-only environment helps manage heat and dust, contributing to a cleaner, safer workspace. The wet-drilling capability also extends the life of the bit, reducing wear compared to dry drilling. It's ideal for longer jobs where precision and extended use are key. The bit is designed for a wide range of tough materials, from reinforced concrete to hard masonry. Whether you're working on industrial projects or professional-level home renovations, this tool is up to the task. This 4" Wet Drill Core Bit is a reliable, high-performance tool. Its durability, precision, and ability to handle the toughest materials make it an excellent investment for any contractor or professional who needs a reliable bit for concrete or masonry. Highly recommended for anyone needing a solid, high-quality wet drill core bit!

Works great. No complaints.

... and you're looking at this product wondering if it can help you do it. The answer is YES but you will need to buy some extra equipment. I had to drill a 2.75" hole through about 12" of VERY HARD brick and this thing did the trick. Here's what else you need to buy: * #16 SDS Plus (TE-C) to 1-1/4" M Core Bit to Drill Adapter by BLUEROCK Tool * Diablo 1/4 in. x 16 in. x 18 in. SDS-Plus 2-Cutter * BOSCH 11255VSR Bulldog Xtreme 8 Amp 1 Inch Corded Variable Speed SDS-Plus Concrete/Masonry Rotary Hammer I know what you're thinking: can I get away with just a normal drill? Answer is NO. I tried a regular drill and a regular hammer drill but become extremely frustrated quickly. The long pilot bit is really critical for when you get stuck deep in the hole. Get the core bit back out and send the pilot bit through several times. Other important tips: * Use the hammer mode. I know it says all over this page not to do that but I couldn't make any progress with out it. Used hammer mode and everything was fine, drill bit is still in great shape. * Lots of water. I would drill 10 seconds, spray tons of water, then drill another 10 seconds and so on. * Drill lots of pilot holes. If you get stuck just drill a bunch more little holes and break out some of the pieces stuck in there. * Don't let brick build up inside the core bit. Always shake it out or pound it out before you collect too much which can cause the bit to get stuck. $300-$350 worth of equipment to drill holes is a bargain compared to what I was quoted. Have fun!

I used this to cut through my concrete to run a sewer pipe. This hole saw worked well. You must keep it very wet or it will get stuck. As I was getting deeper, the cutting became slower, I think the diamonds were wearing out. You need to remove and disassemble it, take a bar and knock out the concrete from inside of it routinely. Also you need a good grinder as it takes a lot of torque to cut through. I burned up 2 grinders on this project. This is a great product for a one time use.

Very impressed. I've core drilled 5 cuts with this thing and every one was perfect (2 and 1/2 inch bit). Cut right through a rebar infested concrete footer with ease. Make sure to use water and rotary drill mode only. If you use impact, you will destroy the bit. I liked this bit so much I bought another as a backup and bought 3 other sizes to go with it.

Great quality

No issues! A cost-effective alternative to rental or name-brand barrels. I purchased this to drill a series of 5" holes into an old stacked-stone and mortar wall. It cut through the mortar with ease. Naturally, drilling through the natural stone took longer, but the barrel cut through the stone smoothly and with ease. With an extension attached, I was able to drill 24" deep clean holes. It's worth noting that this is a wet-cut-only barrel. Where possible, get a garden host attachment for your core drill to keep the water moving. It keeps dust and temperature down and also continuously flushes the cutting surface to maintain a clean surfance for the teeth. The bit still looks great. No damage to the teeth and wear appears minimal. I trust it will cut many more holes.

Garbage do not buy. Would not even drill one hole

Es muy bueno

Worked as expected. Nice to find off sizes. Need holes for pipes to be slightly larger than nominal size

Pudimos hacer más de 5 perforaciones en concreto bastante fortificado. Siempre y cuando se utilize agua como agente enfriador y fuera de fricción. Cumplió con el cometido.

I needed a 7/8 in. bit to core drill 3 in. concrete pavers for pool safety cover anchors. After a dozen holes drilled it is still in good shape. It took a while to get here (Canada) but was worth the wait.

Work great
