What's a good 1/4" bit for yellow pine?

[br928]

I an cutting some 2 by yellow pine and all of my bits only have about 1" CEL. Too short for 1.5" material. What do the guys that cut stair stringers and such use? I would prefer to keep it at 1/4" dia.

I use 1/4'' x 1'' deep 2 flute spiral bit. I make multiple passes so the 1'' cut depth isn't a problem.

If I can keep good hold down I cut with an 2 flute upspiral bit to clear chips well. I make the cut in 2 or 3 passes. The cutting edge should be at least as long as you are doing to cut, you don't want shank rubbing the material.

Stan,

I used to use a 1/2" diameter flush bit (you can easily get them the length you need). If you are trying to cut stringers out of standard 2x12 (or 2x10) material be careful...the lumber has a tendency to crimp and cause havoc on your cut. I'm sure you've experienced that when using a miter saw to cut stringers.

I ended up making 3/4" osb templates of an 8' stringer using whatever rise and run I needed and then tracing it on the 2x. Cutting it on the miter saw is faster for me and the CNC template gives you the accuracy.

I've also cut 3/4" plywood and laminated three pieces together (center is 3/4" osb - cheaper). I found that to be the fastest and best way. It's much stronger than 2x, more dimensionally stable and you can overlap them to create whatever length you need.

If you need to stay with 1/4" & the long cut length, Onsrud 52-564 length of cut 2.25" OAL 4" on a 1/4" shank.
The 3/8" shank would be better
