3/4" Red Oak

Post by metalli445 » Fri May 01, 2015 7:49 pm

Hello,

What end mill would you recommend to cut completely though 3/4" Red Oak? I would prefer a downcut end mill. Thanks!

Any carbide bit will be fine. Red oak isn't very hard as hardwoods go, it's sort of lower-middle class on the Janka scale. I've been cutting a lot of red oak lately, since it looks nice and I can conveniently buy it at Home Depot and Lowes, even though they inflate the price.

My utility end mills are 1/4" carbide up-cutting flat-end bits with 4 flutes. They'll cut just about anything. I've been pocket routing red oak at 800 mm/min with a 1/4" step down without any problems. It can go faster if I want to make more noise. I have a few bits, but this one from Kodiak is my favorite so far... Kodiak Cutting Tools KCT166494 USA Made Solid Carbide End Mill, AlTiN Coated, 4 Flute, 1/4" Diameter, 3/4" Length of Cut, 2-1/2" Overall Length. Even though this is an up-cutting bit, it will cut red oak cleanly without splinters as long as your RPM is fast enough, leaving just fuzz on the top edge. You can do a final facing pass to clean up the fuzzies.

I've also used a 60 degree carbide V-bit to cut 1mm wide features in it with good effect. Another bit I've been using on oak recently is this 1/16" tapered bit from Precise Bits. It cuts nicely through red oak and does fine line work beautifully. I'll be showing off some of those pieces in the next few weeks as I finish up these projects.
