Hilti 6-piece hammer drill bit set, Ultimate TE-CX SDS Plus Drill Bits for drilling through rebar, tough concrete and brick, Drill bits in 5, 6, 8, 10, 12 mm diameter (2151505)

I bought these for a job drilling pre-cast reinforced concrete. Previously I'd tried regular masonry bits but they just wouldn't touch it. After that I tried Bosch Multi Construction bits, those did get through but I was burning out bits after every other hole, even with cooling water. These Hilti bits have been a lifesaver. They go through pre-cast concrete easily and, with some patience, they'll through any rebar hidden in the concrete without damaging the bit. It's hard to believe, but of the two bits in the foreground of the photo, one is unused and the other has drilled multiple holes through concrete and steel with the hammer action on. It's hard to tell the used one from the new one! For regular use on softer materials like brick and breeze block I imagine these could last a lifetime.

Really good, the different Tipp makes a massive difference.I have always used bosch but these are in my opinion better.

They are Hilti. What more need I say

Great set highly recommend go through concrete lintels like butter and stay true, little to no wandering what so ever

Hilti! That's all what I need to say A++

Good quality drills need I say more .

After trying a few other brands I finally found a drill bit that works.. Reinforced concrete fence post = no problem.. reinforced concrete lintel with steel rods = no problem.. restored my faith in holes.

We have an old bungalow with solid walls. The inner supporting wall is made from engineering bricks and is unbelievably hard. Where every other drill bit failed these worked.
