I am looking getting a Milwaukee 5615-24 for cutting mortises. You guys know I told you I wonted to try my hand at some morris chairs for my mom, I am thinking I can use the plunge base to cut the mortises but I am a tough time find a 3/4’’ sprial upcut router bit, I may be better off buying a benchtop mortiser. I am wondering do you guys know where I can find a 3/4’’ sprial upcut router bit.

Why do you want a 3/4 bit?
You would be better of to cut the mortise in two or more times.

Hi Charles,

Woodcraft… has Onsrud HSS Spiral Upcut Router Bit, 3/8” D, 1-1/4” CL, 3-3/4” OL, 1/2” SH, Onsrud# 40-135 for a little over $20.00. I did the same thing at first then I ended up getting the Jet Mortisie Machine, the chisel bits works excellent.

Bosch has one, Bosch 85967M but its very expensive, http://www.nextag.com/Bosch-85967M-NA-SC-506781663/prices-html. You can get away with using a straight bit also, or use a smaller bit and make a template and just use a guide bushing.

Charles : You might try Rockler, MLCS, Woodpeckers, Amazon.com, and others. I’ve never seen a 3/4” spiral router bit…..the biggest I have is a a 1/2”, but they make make them…don’t know, but somebody on here will. Good luck finding one….... later.

like eric said ,
use a smaller bit , and a slightly bigger template and guide bushing .
try it out on scrap first , the big bit will want to jump and tear maybe ,
the smaller one will be much calmer and just do more passes .

I would get the mortiser, but remember, the largest chisel they give you with it is a 1/2” You could always lay them out, then drill out the majority of the mortise with your drill press, then chisel them square.

I have that mortiser. It’s a good one for the price and you can get a 3/4” chisel for it. Good luck and practice on a bunch of scrap! ;0)

You might have to buy the rest of the chisel set, not famaliar with the Home Depot in your area. The chisel are very sharp and do a remarkable job.

Your asking a lot from the machine to chop a 3/4 mortise. You have to have some serious power and leverage . If I want a mortise that big I cut it in 2 passes using a 3/8 bit , I am using a general int 75-075 with a 1 hp motor.
