Jonathan's Hot Take:
Downcut spiral bits are my most used bit when I want a clean edge on the tool-side of my stock.
They're great for stopped mortises, grooves, and dados — and also for hogging out material on the CNC.
These bits provide the HIGHEST VALUE because the Astra Coating makes them last at least 2-4x longer than uncoated bits. This is one of those times that spending a little more upfront saves you a lot of money down the line.
Spiral bits perform 100x better and 100x longer than straight bits. I recommend staying away from straight bits in general, because they dull so much faster and their aggressive cutting profile can be much less safe.
