Customer Reviews

sawdust maker
I knew Bosch made quality tools and router bits so I thought I'd try the Blue Granite set. I've only used the 2 largest bits in the set, but they performed great...never slowed down through concrete and rock.

Work Good, Last Long TIme
WHat can you say about masonry bits> They worked good when new, and they work good after many holes in hard concrete. I noticed that Milwaukee bits have a hex shaped shankfor a more positive lock in the chuck, and these do not. But they work well and last long.

Seems ok for light duty drills
I had the plesure of over hearing a gal on a job site say these where good for high BPM (blows per minute) hammer drills (I'e light duty and cordless ones). So I asked her if I could try one out in my cordless drill on a waste brick, worked great!!! I was fully satisfied that bits this big (I think I used the "½) with that kind of point would drill like the smaller tri-point ones. Now don't misinterpret, it didn't zoom though that brick, but did better than all I've tried yet with that style point. Also they are pretty true from what I could tell, vary little warping and wobble.

I don't know how long they would last or what would happen if you started re-sharpening them but they seem to be perfect for light duty drills.
