I recently purchased a set of 13 1/2” collet router bits from TayTools. I’m new to routing, and purchased the Kobalt router table. Setting everything up, I attempted to make a cut with a 3/4” straight bit in some pine. The cut traveled about 3/4” into the piece, and then ceased to move further. I repeated this with a dovetail bit and another straight bit to no avail.
Description of Events
I’ll describe what happened with the 3/4” straight bit:
I locked the bit into the collet and submitted the router to the table. I aligned the fence along rulers that are etched into the table on either side of the bit housing (approximately 2 inches from the bit’s center). I turned on the router and allowed it to reach full speed. Using a Grr-ripper, I applied pressure toward the fence and down toward the table to secure it. Then, I slowly fed the piece of wood into the bit (end-grain first, but I also repeated this process in a cross-grain fashion). The bit seemed to struggle for the first ~3/4” cut, and then would not cut further. The wood started to scorch from the bit spinning in the same space for an extended period of time. I then stopped pushing because I felt the situation became dangerous.
This situation happened again with a dovetail bit, where I aligned the fence so that it passed over the center of the bit (i.e. 0” from the bit). The dovetail bit cut better than the 3/4, but struggled and caused massive tearout.
Any ideas what the issue could be? Since the bits have carbide tips, I don’t know how I could attempt to sharpen them. The router does not have a variable speed dial. Could it be the RPMs?
