OK drill bit Aug 31, 2010
By Michael Merrill I picked this bit up to drill holes into my garage concrete slab for a automobile lift. I had picked up locally a Bosch SPS+ bit that didn't work properly in my hammer drill. I figured with a brand new quality drill the remaining 5 holes would be easy. Even with drilling pilot holes of 1/4", then 1/2" then 5/8" before trying to reach the 7/8" size of this bit I was surprised how slow and tough the drilling was. Now maybe my hammer drill isn't state of the art, but it is a hammer drill not a normal drill, and the 1/2" bit from a lesser marketed brand cut though the concrete much easier.
I found 7/8" to be a difficult size to find locally, most places go from 3/4" to 1", so Amazon came through where the local places had nothing.
Granite tough!! Sep 06, 2010
By P. Keeton Bit was put into service immediately upon receipt and has drilled with no problems through poured concrete basement walls and concrete stairs. It has maintained its cutting edge very well. I would not hesitate to recommend this blade to other users.

I have purchased at least 8 of these bits. Over the past 3 years I have been working on a huge project (retaining wall) at my lake house. I have drilled perhaps 500 eight inch deep holes into reinforced concrete lintels with these bits. The biggest problem is when I hit rebar - as the bits will wear. The lintels are very dense and contain good sized stones so drill time varries. The bits will cut through light concrete(blocks and bricks) like butter.
I have found a local hardware store that sharpens them for $3.50 - some of the bits have been sharpened twice. The carbide head on these is nice and large and will allow multiple sharpenings - you won't get that from cheaper bits. I bought all mine at Lowe's at about $17 so the price here is very good if you were to buy multiple bits to save on shipping.
