I bought two of these SHDiamtool core drills, a 50mm and a 32mm for custom work on sandstone blocks 2 to 2-1/4" thick. I had 12 blocks that needed one 2" hole drilled completely thru and four 1-1/4" holes drilled an inch deep, not all the way thru.These drills do not come with a pilot drill, so I made a template out of plywood and 2x4s with the same hole sizes and layout as I needed for the blocks. That made it easy to be sure the drill didn't skip or wander when making initial contact with surface of stone. I used a drill press with water coolant and checked a core drill speed chart to make sure I was in the ball park for spindle speed - used 1080 rpm for both sizes - and these things cut thru sandstone really well and quite quickly using only moderate downfeed pressure.This pair of core drills performed well and did exactly what I needed - I would buy them again, but they hardly show any wear on them after 12 holes with the 50mm and 48 half depth holes on the 32mm. Make sure you have or buy the correct arbor for them and you should have no problems if you keep them cool with water, use the correct spindle speed and don't use too much down force. ### ⭐⭐⭐⭐⭐ Excellent core bit *by on Reviewed in the United States November 4, 2025* I used this to core drill 6 holes on my granite tread steps, it works great with the corded hand grinder! I use the garden hose to spray water as I’m drilling. The core bit still looking great with no signs of damage! It exceeded my expectations! Excellent product! ### ⭐⭐⭐⭐⭐ Worked as advertised, 4in diameter went through tile and 3in of concrete with ease. *by on Reviewed in the United States April 28, 2024* I can't speak to it's longevity or durability as I only needed it for this one job, but it's a well built tool. It went through the tile and concrete in a couple minutes. Wasn't great at going through the wood. It pretty much burned it's way through sub floor. For this 4in diameter I recommend using a plug-in grinder for the power.Overall happy with the performance and ease of use. Definitely use earplugs, a mask and safety goggles. It makes a lot of dust. Follow the instructions. The hole was exactly where I wanted it, did not walk off center at all. ## Frequently Bought Together - SHDIATOOL Diamond Core Drill Bits 1-3/8 Inch for Hard Stone Concrete Marble Granite Brick Laser Welded Dry or Wet Hole Saws 35mm - SHDIATOOL Adapter for Core Bits 5/8-Inch-11 to M14 Thread --- ## 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.mx/products/75472856-shdiatool-diamond-core-drill-bits-1-3-8-inch-concrete](https://www.desertcart.mx/products/75472856-shdiatool-diamond-core-drill-bits-1-3-8-inch-concrete) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-08-12*
