I purchased these bits for a project and was left disheartened with the outcome. My analysis of this product showed that they were poorly made and were unable to keep a consistent cut throughout the wood. The bits were supposed to be durable and long-lasting, a claim that was quickly proven false. While they were affordable, they fell short in every other department .Stick to higher-quality brands in the Industrial and Scientific cutting tools realm to avoid frustration..
This was my second bit from Whiteside. I use 1/16 for thin lines on wooden signs. The first lasted two marks, about 30 minutes of work before it broke. I got my second one yesterday and today it broke five minutes after using it. I will not order again.
