First time milling.. not sure what I'm doing wrong.

[Mitch Alsup]

My machine never came with a window.
I can see a use for it when doing interrupted cuts, where my lathe spews chips all over the shop.
I can also see a use when machining brass, bronze, and cast iron.
I just stand to the side out of the line of fire.

Kinda off topic of your milling question but what tool holder are you trying to fit that parting tool holder in? Did your QCTP set not come with a parting tool holder something like this?

I just used an angle grinder to grind the tool down.

Do you guys keep the window on your machines? Mine has a switch where it shuts off the machine if it's on open position. It's hard to see through the plastic.

Remove the C clip from the top of the window's swivel post and the whole post will slide out, window and all. The switch will be in the active position with the post removed, so your good to go.

This one. It'll go into the tool you posted, but no matter how tight I crank the set screw, it pops out easily. So, I tried putting it into a regular tool holder, but it's too thick to go in, had to trim down a bit off the top and bottom of the picture I posted.

Yeah, I just took the whole thing out.

Cobalt is kind of in the middle: not as brittle as carbide but harder than hss and can be sharpened with conventional wheels

To my experience, Cobalt HSS is just that, an enhancement of HSS, a higher preforming version of HSS, it is nowhere in between HSS and carbide. One thing about it is that it is much harder and much more time consuming to grind than normal HSS alloys. One that I use is MoMax Cobalt; damn hard and tough stuff!

There's your problem. That parting tool holder you are trying to mill down is meant to be used in a lantern post type tool holder. You need to take just the tool bit (the shiny HSS blade) and put it in the tool holder of the QCTP.

I ran out to the garage and took a quick pic that might help.

Thanks, I tried doing that, but the blade is too small for it. I'll have to buy a new one.

What do you guys think of end mills with replaceable bits? I'm thinking of getting one and just getting carbide inserts. it may be cheaper this way?

Just broke a 3/8" end mill trying to take off .005 off a mild steel square stock. Also, I added a lamp to the mill. I don't know why it doesn't come with one standard.

I also wish I bought the smaller vise. I bough the 5" one and had no idea how large it was. This thing is heavy.
