## Description

SHDIATOOL Diamond Core Drill Bits 3 Inch for Hard Stone Concrete Marble Granite Brick Laser Welded Dry or Wet Hole Saws 75mm - desertcart.com

Review: Excellent core bit - 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!
Review: surprisingly good value for an imported tool - Wasn't sure how well this was going to work but was pleasantly surprised with results. 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.

### ⭐⭐⭐⭐⭐ Worked as advertised, 4in diameter went through tile and 3in of concrete with ease.
*by A***R on 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.
