1/2 Inch x 39 Inch SDS Plus Rotary Hammer Drill Bit, Carbide Tipped Concrete Drill Bit for Masonry; Brick, Stone, Concrete (1/2" x 37" x 39")

Works as intended and is of a good quality steel.

Great product, works great

For a budget tool this worked amazing. Fit right on a harbor. Freight drill took me a while to drill through 30 inches of concrete, but I did it in about an hour.

Needed a thirty five inch hammer drill bit for a five minute job. Got it in record time and did the job I needed it to do flawlessly. I was able to get the thirty five inch holes done easily with the bit end being made for just doing things like this. There was no bending of the bit because I let the hammer part of the drill and the drill bit itself do all the work for me. Four Stars ⭐️⭐️⭐️⭐️!!!

Outstanding product. Theough filled block like butter and holding up after 10 uses. Makes a great pilot bit to make openings on other sides of walls for bi-direcrional drilling.

This drill bit held up much better than expected and it got the job done quickly.I was drilling through dirt and rock to get a three foot head start in driving an eight foot grounding rod. A few times when I would hit some rocks the drill bit would flex a lot more than what I was expecting, but it held up well and did not break. When it would start to flex, I would let up on the pressure until it was able to get a hole started on the rocks, then it was able to take more pressure.When finished, the drill bit did not show any signs of wear, such as bending or fatigue. And the carbide tip was also intact and showed no wear.I'm planning on using this for another hole through rock and dirt, so I have great expectations that it will get that job done too.

As promised its a super long bit. Works in my Bosch bulldog hammerdrill

Used this in a regular drill to drill a few holes in concrete. Worked just fine.
