BoschHC2083 1/2 in. x 6 in. x 8 in. Bulldog SDS-Plus Rotary Hammer Bit

Coupled with the Bulldog rotary hammer drill, it made quick work of penetrating a 6in slab to lay in rebar reinforcements for a block wall. While I'm not a contractor, I have used the Bulldog bits for years with great success and no failures.

Did exactly what I needed it for

So far we have had no issues. Make boring a 1" hole nice and easy.

Muy bien

I've used that drill bit for a couple of weeks and don't regret I got one so far.

after a couple drilling, the head is not sharp as the first drilling.

.Carbide is a durable material and worth the money. Head design is not for soft woods. After 20 minutes reached a depth of 4 inches. Others said they used it for concrete. So my bad!

Used to drill holes for wedge anchors for a car lift. Instructions on the lift said to drill and lift to clear the material but this bit is awesome as clearing the material by itself. The holes were perfect and I was able to apply 125ft lbs of torque onto the anchor bolts with no issues at all. This is the best concrete bit I have used!

Really solid rock bit. I've done 40 or 50 holes in granite and some in limestone, basalt, and gniess.Still going strong. Highly recommended.Beats the pants of the hardware store bits that drop the carbide after 6 holes...Be sure to grease the sds drive and go lightly, you don't want to force the bit against the stone. It needs to be able to bounce a little to work efficiently.

As seen in the photo, this was a relatively expensive failed experiment. I attempted to use this drill bit to make a water feature. I was barely able to make a mark before the bit was dull; even with flowing water to keep the bit from heating.

Good thing i bought 2.First one broke (more like shattered) in 3 pieces not even 1" into the first hole.In 20 years of construction and working with sds drills regularly and thats the first time i have ever seen THAT happen.Bosch bulldogs are generally usually good bits. Not sure why this happened, thinking i wound up with a dud.

Cette mêche est bonne faire des trou dans le béton. C'est pas la meilleure mêche que jai eu mais pour quelque travaux léger elle est correct! Mais pour des gros travaux je préfère pas!

i just drilled 1 hole up to now and it worked fine on a standard hammer drill. you just need to be carefull to fit it in the jaw correctly and it works.
