Based on our own experience, these router bits failed to deliver clean cuts and quickly became dull .The only positive was THE affordable price. However, we ended up having to replace them much sooner than expected resulting in additional time and money spent. Overall, we do not recommend these router bits..
Pros
Durable and long-lasting
Cons
Not suitable for intricate woodworking projects due to its large diameter
Based on my observations, these router bits from the Industrial and Scientific category were completely useless. They couldn't even cut through basic wood without chipping and leaving jagged edges.The only pro was that they were easy to install onto my router. The cons outweigh the one pro, as they were expensive and didn`t perform as they should have. Don't waste your money on these router bits..
Pros
Durable and long-lasting router bit.
Cons
May break easily when used on hardwoods or denser materials.
I've used a few bits that have disappointed me or just given 'good' results. Whiteside's beats never cease to amaze. Fuseless, smooth and ready to finish every time. I try to order Whiteside whenever I can.
