All the review were great
Your experience may differ from mine. The bit I received had a very hard time drilling 3/4" deep holes in Baltic Birch plywood. I only needed to drill three holes but half way through the second hole I gave up. I inspected the bit and saw a discoloring at the edge of the Chip Breakers, which suggests I overheated the bit and it lost it's temper. I didn't have another bit if that size, so I sharpened it with slip stones and finished my three holes. It cut well after my sharpening. I believe the bit I purchased had a unexceptionably low heat tolerance. All the reviews on these WR bits I read were very positive but my experience was quite negative.
