Review: Good Price and Performance - I used this to round the corners of my sinder block pillars under my house so my vapor barrier won't tear on the edges. It needs to be installed on an angle grinder with a collet adapter though.
Review: These bits are awesome! - Long lasting and easy to use! I used one bit to roundover two sides on over 200 cut pavers for my fire pit. I used a little water while cutting to keep the dust down. Highly recommend these bits.
