Astra Coated Solid Carbide 3/8″ cutting diameter 1/2″ shank 1-1/4″ length of cut. 3-1/2” overall length Up Cut Made in USA These tools are coated with a proprietary high performance *Astra coating* that allows higher speed & feed rates as well as 2x the extended tool life & increased lubricity in abrasive material Jonathan's Hot Take: Up-cut spiral bits are my most used bits when I'm trying to clear chips or get a clean edge on the side of the stock furthest from my tool. 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
