SF20-700mm ROUND SHAFT

$20.95

  • Model: SF20-700mm
  • Shipping Weight: 2kgs
  • 2 Units in Stock

You are looking at a brand new 700mm length of 20mm hardened chromed shaft SF20 for your CNC router mill.

Features include:

  • 700mm long
  • Both ends have been machined to specification with a bevel installed (not just straight cut)!
  • Shaft is case hardened, if you use normal steel shaft the bearings will cut them up in no time, make sure what you buy is case hardened!
  • Suits  X, Y or Z axis
  • No more unwanted errors in your machining work!
  • Item located in Melbourne, so you will get it fast and packed well!    Don't risk having it shipped from overseas!
  • Also available in 10mm, 12mm, 16mm, 20mm and 25mm
  • Brand new!
  • Please check out my other CNC items & we do provide combined shipping!
  • As the shafts are hardened, they are very difficult to cut (i.e. you will not be able to use a hacksaw, etc to cut).  If you do need to cut, use either a lathe with a tungsten carbide cutter, a specialized saw (i.e. brobo), or a grinder (not recommended as the heat produced from the grinder affects the shaft hardening).  So basically it is highly recommended to buy the length you need as it is a b**ch to cut.
