Sabre Tool 1-1/2 Inch x 22 Inch SDS MAX Rotary Hammer Drill Bit, U-Flute, Carbide Tipped for Brick, Stone, and Concrete (1-1/2" x 17" x 22" Double Flute) SDS MAX Hammer Drills ONLY

Been using to drill out an 18" deep foundation, 6" wide. The length is ideal for using with my SDS Max rotary hammer/drill. It has held up well to the heavy use.

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

Drilled 12" deep holes through granite bedrock with no problem. Used for Dexpan application

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

Drilled roughly 20 holes in ledgerock before carbide came off. Was disappointed until I read other reviews indicating this is on par performance for economy drills.

Didn't even make it through one job.Broken

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

Perfect bit for our fencing installations.
