I bought a 3/8" spiral upcut bit to create mortises. While making a
few trial cuts, it seems to me that the bit does not readily "drill"
into the wood and there is usually some burning while plunging. I'm
wondering if this is normal, or should the bit easily plunge onto the
I've been trying this with poplar and pine. The router is a Bosch 1617
with var speed. The bit came from MLCSWoodworking.com
If I want to make a 3/4" deep mortise, how many passes should I need.
(i.e 3 passes at 1/4 inch deep each pass). Or should I be able to make
the mortise in one pass?
Thanks for any info or recommended techniques.
I did the same thing - I got a 3/8" solid carbide spiral upcut by CMT
(at $50+, one of the more expensive bits I own). It plunges and cuts
mortises with no hesitation or burning - I think I did 1/4" - 3/8"
deep per pass. Highly recommended mortise method, though I'd probably
look for a solid carbide end mill in the future to save some $, as per
recommendations from this ng.
I've had good luck with MLCS bits in the past, but maybe their spiral
bits just don't "cut it". (Sorry, couldn't help it...) Is your bit
solid carbide? If not, that should make a big difference.
