Greetings All,
I have been making Through Dovetails and I managed to absolutely bake a Freud 13/32" (Dia.) Double Flute Straight Bit with 1/2" Shank (12-112) for the Pins. For the Tails I was running ~23,000 - 24,000 RPM with the appropriate Bit and the speed of the above mentioned Bit for the Pins was not much different. Wood is Poplar, 11/16" thick. After a dozen or so cuts that Bit was a paperweight.
Obviously I am doing something gravely wrong there. Maybe I am not not moving fast enough or I'm way to high on the RPM's or perhaps both. Circa 2002 - 2008 I was deeply into Routing and never had any issues with Freud Bits albeit I was using a Router Table. These Through DT's are being done on a Porter Cable 4216 Jig.
As always, any input greatly appreciated.
Best,
Lyman
