Speed refers to the RPM of the machine spindle, i.e. the rotational speed of the tool on a mill or workpiece for a lathe. Establishing the rpm and feed rate for end mills and drills can seem like sorcery to many people, especially hobby machinists.

Using the SPEED determined above, we will make a series of cuts at gradually increasing FEED rates and examine the chips and kerf produced at each step to find the sweet-spot. The characteristics of the sweetspot in both woods and plastics share some common features. If your feed to too low for the spindle speed, the chipload is too small.

End Mill Feeds and Speeds. The most important aspect of milling with end mills is to run the tool at the proper RPM (revolutions per minute or spindle speed) and IPM (inches per minute or feed rate). We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.

The chart below provides the suggested chip load starting range typical for material type and tool diameter in use. This calculator provides a starting reference range only for shank tools and is based on cutting depth being equal to cutting diameter of the tool. Depending on depth of cut, this range needs to be further modified as follows:

I buy the carbide end mill PCB bits off ebay and have had pretty good luck with them. They range in size from .49mm to 1.37mm. I've used them for cutting oak and plywood and typically I'm not cutting very deep. When I do break one it's no big deal since they are so inexpensive (a box of 10 goes for $10 CDN with shipping).
