10mm/0.4inch Diameter Carbide Tipped Masonry Impact Concrete Drill Bit SDS-Plus Rotary Hammer Bit 150mm/5.9inch Long

Worked well drilling into concrete porch steps to install hand rail

Received as expected fair quality!

I had to anchor an awning, this bit on my sds worked smooth as butter on my concrete patio

First let me say that this bit was the size and strength that we needed. It arrived on time and well packaged. The quality was great so I only needed one bit for all the holes we drilled. BUT the shaft was a triangular shape and did not hold securely in my hammer drill. There was a wobble and it would come loose often. Frustrating but we got the job done.

It works good just keep it wet

Affordable and gets the job done very well. I only needed to drill a couple of 3 inch holes, but the bit seems very durable and could have handled a few more.

Drilled 16 holes to anchor a gazebo to a cement pad and got the job done, so 5 stars from me.

Drilled 4 holes into the concrete slab . It took minutes and I had 4 nice clean holes
