This bit provides accurate centering, making it ideal for anchoring. 5 piece set: 3/16"x4"x6", 1/4"x2"x4", 1/4"x4"x6", 3/8"x4"x6", 1/2"x4"x 6"

I bought these because I struggle with my battery operated hammer drill will tap con supplied drills. My large hammer Bosch hammer drill is a bit overkill and I hate using a chord. However it is worth it as it makes the job hassle free and works every time. I have only used them about 6 times but I am sure they will last much longer than tap con drills
