### ⭐⭐⭐⭐⭐ This with a cordless impact driver makes life beautiful again :-)
*by J***S on February 5, 2026*

Great set for the price. Used up to 2" so far with my Milwaukee impact driver and it's a beautiful thing when compared to a hole saw or paying $1500 for a dedicated cordless tool! Wish I would have bought it a long time ago!
