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

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

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.

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

Received as expected fair quality!

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

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