10-Pack SDS Plus 3/16" x 6" Rotary Hammer Drill Bits, Carbide Tipped for Brick, Stone and Concrete

Fast shipping. Product worked well.

These are considerably better than the $8 M-brand ones at home depot. The $8. often broke after one hole, these drilled 10 int he same wall twice as fast and not one broke. So I guess I only really know the 1st one was 10x better. I hope the other 9 are just as great.

I was screwing some boards into my foundation (garage wall concrete). I used Tap Con screws. I start with a Milwaukee 3/16 carbide tip bit. I went through a couple of those. They were good for about 5 or 6 holes each. One eventually bent, and the head melted on the other. I then tried a Tap Con bit which was not up to the task.Theni ordered these expecting ai would need a few. These look impressive and seem to hold up. But for my purposes, drilling about 3 inches into solid concrete, they did not work. I could only get in about a half inch. I went back to the Milwaukee and it worked the same as before.These do seem like sold bits, but just not for solid concrete. They're probably fine for brick etc.

They work good I drill 16 holes and no problems I Took my time applying small pressure letting the drill and drill bit do the work

Absolutely the best way to pilot blue screws. In concrete, they cut like a hot knife through butter.Don't be misled by discount bits. These are the least total cost solution by lasting longer and drilling faster.

arrived on time as described

Llegó bien empacado y en excelentes condiciones.

Not true 3/16...slightly larger so 1/4 Tapcon screws strip. Can only drill about 5 holes before the tip gets hot and melts...even with dipping in water.
