LittleMachineShop HiTorque Mini-Mill. (i can haz?)

Mini-mills, from what I’ve heard, are a sensible “hobby-shop” alternative to picking up an old used Bridgeport.  They seem to hold up pretty well and they’re a whole lot smaller and lighter (read: no riggers needed to move one in to your shop), they don’t need to be rebuilt (yet) and for making the occasional part out of aluminum or mild steel, it seems like you can’t go wrong.

Here’s a good site with a comparison chart of what’s available, at the LittleMachineShop.

Here’s the one I want: the HiTorque Mini Mill.

(I loves me a good spec chart…)

…and the price?  $689, without tooling.

So, i can haz tooling too plz?  Check this package out: The Tooling Kit (R8 Mini Mill).  That oughta be enough to get me into some serious trouble…

This comment from my buddy Bryce, Machinist Extraordinaire:

“Looks perfect for you. I would consider the belt drive speed increaser. 2500 rpm is not a lot for a small mill like this. Cutting aluminum you can’t go too fast. I regularly run a 4 inch face mill at 15,000 rpm. on the machining centers. 

.0625/ turn is a little awkward, but hopefullly the dials are marked in thousands.”

  1. Listen to the Brycester; it’s perfect for you.

    We don’t yet have the speed increaser, but we expect to have them in by Q4. And yes, the dials are marked in 0.001″.
