Review on DEWALT DW5230 8 Inch 6 Inch Carbide by Mike Starling

I bought 2 for a job that required fixing 5 commercial mall trash cans to standard concrete. These are 20 holes approximately 1.25" deep for 3/8" x 3" wedge bolts. I got to the eighth hole and noticed a lack of power and a blue drill bit from high heat. Switched to my second backup bit and same, got to hole 16 and barely drilled. Luckily I had a Bosch HCBG12 Blue Granite bit to finish the last 4 holes. A big noticeable improvement, but at $9 a piece it's almost triple the price. For the price paid, the DEWALT DW5230 bits worked as expected. 3 flats on the shaft are a plus. I recommend them, but there are a few supplements on hand.
