You can get a 2.5" - 3" bit for $50 -$80 on Amazon... Hell of a drill and a great bargain. I have owned three SDT 85's prior to this because the STD 85's water feed is a major flaw. Had this one for month's and drilled hundreds of holes... still works perfect. Worth every penny. **Q: I bought this with 3" and 4" core bits, but there is no pilot bit. Can you refer me to the appropriate pilot bit.** A: I have used this drill with up to a 4 1/2" bit. I do not use a pilot bit for drilling on flat surfaces. I drill mainly into masonry and concrete to anchor newel post for railing and fencing. This method would not be advisable for counter tops I think...We use a ply wood or composite lumber strip two or more inches wider than the hole and drill the appropriately sized hole with a hole-saw in it, centering the hole over my mark I use that to get the drill started. Once it is 3/16" or more into the material you can remove the guide if you want. It works well for us. **Q: What's up with the water connection? I read it needs to be replaced or something. I would need to be able to hook up a garden hose to this** A: It connects to a standard garden hose, however every connection on mine was loose and had to be tightened in order to stop it from leaking **Q: I am new with core drill. is there anything else i need to buy if i just need to drill a 4 inches hole? thanks!** A: You will need a 4" core drill bit if thats the hole size you need. It will screw onto your drill and you are ready to go except for water and power. Good luck. ## Frequently Bought Together - CORE DRILL Model 4Z1 2-SPEED CONCRETE CORING DRILL by BLUEROCK TOOLS - 2" Inch Diamond Wet Core Drill Bit 1-1/4” Threaded by BLUEROCK Tools for Concrete Rebar Asphalt Brick Rock Masonry Hole Barrel Coring - 3" Inch Diamond Wet Core Drill Bit 1-1/4” Threaded by BLUEROCK Tools for Concrete Rebar Asphalt Brick Rock Masonry Hole Barrel Coring --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/11058761-bluerock-4z1-4-concrete-core-drill-110v-1500w-2-speed](https://www.desertcart.sn/products/11058761-bluerock-4z1-4-concrete-core-drill-110v-1500w-2-speed) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-18*
