Sherline Taig ISO-20 Headstock 38271

Everybody loves a scratch-N-dent sale!

This is a Sherline mill headstock mounted with an ISO-20 spindle. It can be mounted to a Taig mill when using an adapter. The reason this one is a scratch-N-dent model is because of two reasons: The headstock has some scratches/marks on it and the ISO-20 spindle has a .003" runout. However, the headstock has never been on a machine, the bearings are new and the spindle arbor is new.

One of the neat features about your new ISO-20 headstock is; using the included drawbar, you can easily insert and remove the ISO tooling with a cordless impact driver (these are pretty cheap locally, eBay and Amazon). You simple buy ISO-20 tooling and remove the pull stud, if it came with one. You'll be using the threads that the pull stud would use. Then simply your drawbar and impact driver to pop the tooling in and out..and that's it. You now have a fully functional quick change ISO-20 headstock.

Great features include....

  • Low Profile Mounting - You'll be able to have maximum Z axis work envelope because the spindle only sticks down by 5mm. This is a huge plus for small mills.
  • Your ISO-20 Tool Taper Seats Into the Bearing Area - When engineering a spindle, you optimally want the tool taper as close to the bearings as possible. This makes for a more rigid setup. This gives you better cut quality and cutting speed. This design also doesn't add any unwanted leverage against the bearing, like you would have with many other spindles that stick out further. The benefit here is reduced bearing wear, which means a longer bearing life.
  • This can be used on Sherline or Taig mills. You'll need to order the Taig adapter with stud to use it with a Taig mill (very simple installation). Or, you can simply make a Taig adapter.

Things you should know: This is an OEM direct fit to Sherline mills, however can use an adapter for Taig mills. We do not currently have any pulleys in stock that will fit the 30mm shaft. We should have them in October. Otherwise, you can make your own or bore out a Sherline OEM pulley to 30mm. This spindle can't be used for ATC purposes (unless you design one that can screw and unscrew the drawbar automatically). It is not designed for use with an ATC petal clamp. Tooling not included. Any blackish appearance is just from the hardening process. I suppose you could polish it if you wish. Otherwise, it doesn't affect anything.

We only have a few of these and there are advertised in multiple places...so, don't wait or you'll totally miss out!
