I purchased an Amana 1/2" 14 degree 1/4 shank dovetail bit to make some drawers. It has become dull after only 4 drawers. Is this normal? I have tried to go at a slow pace, not really getting any burning, just a lot of chipping and I can tell the bit is feeling a little bogged down. Are Amana generally considered good bits or should I be using something else? It's not like they gave it away, I think I paid $17 for it. It has to be 1/4 shank, I'm using it in my PC 690 with a collar for the dovetail jig.
Thanks in advance for any assistance.
