3" Wet Diamond Core Bit for Concrete & Masonry, 1-1/4"-7 Arbor | General purpose, core drill concrete and masonry, 14" drilling depth, wet only, diamond hole saw

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! Cuts like butter. Ran this on a vevor core drill to install new ada signage in a sidewalk. Cut through 8” of 3000psi like the best of them. Minimal noticeable wear after 6 holes. Looks like it will last a long time!

Great bit. Went through a lot of rebar and it held up well. I rent the drill stand and I’m always worried about hurting a rental bit. This is great didn’t have to worry and saved the bit rental. Will be buying all the sizes I commonly use.

Worked well. Drilled three blocks with filled cells and rebar. Went slow through rebar but drilled holes four and five with no rebar just fine. For the price would buy again. Only drawback is the teeth should be a little more oversized to the interior. Had to clear plug to allow water flow about halfway through each hole.

Needed it for a last minute job out of town, next day delivery came in handy and equipment worked just as it should. We use it for reinforced concrete cutting that may include rebar mesh and others. Material quality is great as it held up through the whole job. Easily hooks on to your core drilling machine

This worked well. Water adapter I used the "DaduoRi 1 1/4"-7 Male Thread to 1/2" Hex Shank Core Drill Adapter Kit- Water Injection Capable, Includes Solid Brass Hose Quick Connector - Compatible with 1 1/4"-7 Core Bits for Concrete Drilling" and it worked perfectly. Drill used We used hammer drill in drill mode only - BAUER 7.3 Amp, 1 in. SDS-PLUS Type Variable-Speed Rotary Hammer. I would recommend a different drill as this drill had a lot of play in the connector and it caused drilling to take quite a bit longer. I previously purchased a dry bit 4 -1/2 and found out the hard way that was to small for a 4 inch pvc. So dad build a box to stabilize the first few inches as we could not drill the pilot hole. This drill bit did come open but was unused and worked great! I believe it still took use about 1 1/2 hours to drill the hole through 10 1/2 inches of concrete.

The shaft is well constructed, but there is so little abrasive on tip, I could only drill one hole. Compare with dewalt bit, which has alot of abrasive. I bought this for the length

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.

Drilled through concrete pavers using only a rotary drill. Be sure to clean out the core in the bit.

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.

Work great

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

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.
