### spindle speeds for endmills etc - practicalmachinist.com

· Looking for some rules of thumb regarding spindle speeds for common end mill sizes. I naturally tend to spin the cutters too slowly and work my way upwards. I was just cutting with a large (6") fly cutter and it took a while to get to the correct(?) speed of 322 rpm.

Contact Now### The Skinny on End Mills | Make: - Make: DIY Projects and ...

Spindle speed that is too slow paired with a faster feed rate can result in dulling of the cutting edge, deflection of the end mill and possibility of breaking the end mill. A good strategy when selecting a cutter is to attempt to balance feed rate and spindle speed by performing two passes on the work piece.
