Review on 🔪 DEWALT DW5229 16 Inch 12 Inch Carbide: Precision Cutting Tool for Ultimate Performance by Charles Lewellen

This is a great drill bit for drilling 8 inch thick concrete block walls and then you have 3/4 batten strips and half inch drywall to drill in at least 9 1/4 total 4 inches to go inside from the outside of the house. This carbide drill bit goes through very easily and is perfect for my regular rock drill bit. Lasts a long time without fading.
