2" Aggressive Wet Core Diamond Drill Bits for Concrete and Other Masonry 1-1/4"-7 Threaded Arbor

Es una herramienta super útil para el trabajo que realiza mi esposo. Estamos muy conforme con el producto

Great drill bit, keep it wet when using and lasts longer.

I thought this was a cheap price compared to the high end black bit but it turned out to last just as long. It might be slightly slower in very hard stone and old concrete. But it does last. For 1/3 the price. Nice.

Hole saw is great for its price. I made 3 holes mounted on my Milwaukee rig and there is plenty of teeth for more. It should be used wet only with a good water system, otherwise it will not last a bit.

For the price i paid for it, i never expected it to last foreve, it might have had a ruff up or two and missing 2 teeth but it's still going. 2 teeth that has gone, is by no fault of ours but it is grinding still.
