BOSCH HC2000 5/32 in. x 2 in. x 4 in. Bulldog SDS-Plus Rotary Hammer Bit

I was drilling holes for concrete anchors and with previous home depot drill it took several hours to drill 1/4 inch deep. It was very hard concrete. With this drill It completed the job way faster.

I had to drill through a 10 in. Concrete wall but start from inside 2x4 wall this was long enough I used a Milwaukee rotary hammer it took about 8 minutes to get through drill still looks fine.

Love it, needed this for business camera installation which worked out perfectly.

Muy bien

Get what you expect.

These are very good bits. I use them regularly to drill into concrete and was purchasing them at the big box store. This is a great deal so I buy them in quantity. It's good to always have them on hand when one does eventually fail.

Concrete bit

Works great, and long lasting

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.

I broke 3 bits out of my 25 pack drilling 9 holes in the first 5 minutes. I was drilling in brick wall. Pretty soft bricks. I had Hilti bit before it lasted about a year. Yes about a year with light usage. I only have a Hilti drill, (NOT bOSCH) soft start, never push, let the drill do the work and I still managed to break 3 bits in soft brick. I'll have another job to drill next week if I break another few bits then I'll change my rating from 2 to 1 star. Update. I am raising the rating to 3. Next drillings vent well with no losses though I was very careful not to push on the drill. They are delicate.

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!
