Sabre Tool 1/2 Inch x 21 Inch SDS MAX Rotary Hammer Drill Bit, U-Flute, Carbide Tipped for Brick, Stone, and Concrete (1/2inches x 16inches x 21

We have used this bit several times and it's still acts as if it's brand new.

Looks to be built well and used only once with ease.

Only used this bit a couple of times so far. It works great. Installing t-posts in solid blue rock. This bit effortlessly drills 16” deep holes just the right size that you can knock a standard t-post in easy with a hammer, not a lot of force involved, the weight of the drill and this bit is all the force needed to grind out a 16” deep hole in blue rock in about 3 min, it dosent snag or twist much,and the little there was, was easily controlled, time will tell how well it holds up

Doesn't drill coral without a pilot hole about 1/2" predrilled

Perfect bit for our fencing installations.

i have 4 techs using these drill bits and they are all telling me the same thing, the normal hilti bit you have to hammer the anchors in, with this bit the anchors are just falling into the hole and not biting as they should. won't buy again $280 later!

Good product I'm very happy

Worked for 5 holes. After about 30 seconds to 1 minute of drilling I would give the bit a break to cool down. After the 5th hole the bit was rounded off and not cutting.

For the price and only needing to drill 3 holes 12” deep….Perfect!
