I ran a #5 Cincinnati vertical at one shop years ago, with a 50 taper, and a 6" facemill, it was crazy the material that it would take off. We only used it on occasion, so we never really got proficient at running it. watching the chips fly was fun though!

Thanks for the giving it a bit more credit there graywynd, But I'm sure you do know a dingy can float...

Wrong fu floats about as well as the Titanic after it danced with the iceberg
but it will remove metal if you are as patient as cutter.

As Greywind and others have said Each tooth in the cut requires some horsepower to remove a certain sized chip and each cutter works best with a specified chip load. ( feed rate plus depth of cut set this )
There are two requirements placed on the machine by these tool dependent requirements they are sufficient horsepower and adequate rigidity to work without destroying tooling and leaving an acceptable surface finish on the work.
If you are patient enough they work. If you value your time rong fu or any other smal light mill = wrong choice.

No, I get it, and the choice was a bad one for what I want to do but till I fix my floor problem its what I have to deal with and I do appreciate the help and advice...
I was jokingly meaning he gave the mill drill a wee bit more credit because a dingy can float meaning the mill is a bit of an anchor...
you guys at the beginning of my machining tooling adventure have all been very helpful and pointed out the good the bad and the ugly like when I was buying things I didn't need or should come later etc... because I found my self with a few things I no doubt didn't need and without tooling I did need and didn't have
as you can see I haven't been buying blindly then asking after the fact but now I've developed a kind of gunshy sort of issue on buying anything for the most part when it comes to certain tooling without asking first now...
but the fly cutter as cutter said if it works for his Mildred it should work for mine as well but will only work as good as the operator here
So please don't feel I am not appreciative of the help and advice you guys give me it is one of the reasons I'm here and still here...

and if you were going to buy one of the mentioned in this from the banger-good website and which one would you buy from lowest to lets say middle of the road to chose from off the BG site...
IIRC you have an RF30 or so.

Go with a 4 flute face mill about 3" diameter, cheaper replacing 4 inserts than 8 at a time, as others stated keeping up chip-load with more than 4 will be a waste.


get a cheap 5 piece fly cutter set there may be a time you want to open up a hole, a selection of diameters will help get into tight slots.

each size fly cutter will require a tool bit for its size slot, I don't recall if mine starts from 1/8" or 3/16" on up.

Those little mills are not a terrible choice they are just limited
The problems start when you ask them for more power or rigidity than they have.
Since most of the tooling and almost all of the better tooling falls into that category and most light duty mill owners do not have the experience to make intelligent choices mistakes become the rule rather than the exception .

I was not down playing any mill with my thread.. More of posting links to show you don;t have to run scared of tooling cost.. I also think running a horizontal Arbor with good cutters will probably be where I end up over the face mill for most things.. Found New USA cutters on Amazon Cheap..

Like this one for $65.00
