GT2 Alum.Timing Pulley 5mm shaft 20 tooth for RepRap Prusa Mendel Huxley CNC


Excellent GT2 pulley for building RepRap 3D printers, CNC and lasercutting machines
This is the best quality GT2 pulley available !
It works perfect with the flexible GT2 timing belt we also sell.
If you've ever worked with plastic pulleys before, you know it's better to go for a metal pulley.
A plastic pulley tends to break, chip or wear out after a while.
This strong, lightweight GT2 pulley is double flanged, which prevents a timing belt to slip from this pulley.
It'll fit a 5mm shaft. 
However, if your steppermotor (i.e. NEMA23) requires a larger bore-hole (6mm or even 1/4 inch), you can modify this hole with the proper sized HSS drill. 
As a test for one of our customers, we've successfully enlarged the bore-hole to 1/4 inch on a lathe.
