Description of DEWALT DW5227 32 Inch 6 Inch Carbide
The product is 5/32x6 Perc Drill Bit. Easy to use. The product is manufactured in China. ROCK CARBIDE tip maximizes carbide surface contact for longer bit life. Four flute design cleans debris out for fast, efficient drilling. Three flats on shank eliminate bit slipping in chuck.
Bought to replace a Tapcon drill bit. Doesn't work as well as Tapcon but did punch a few holes in cement backed brick. Most likely you'll drill a few more holes before it burns out.
Pros
ROCK CARBIDE tip maximizes carbide-to-surface contact for longer bit life.
I bought this tip to help with Tapcon screws; Tapcon brand bits are a bit pricey so this bit seemed like a good deal. To date I've used it to fasten just over 25 Tapcon screws in log walls, almost all in cement grout lines. At these prices I will order two or three more bits. They are of good length and seem to retain their sharpness after many uses.
