Blue Coating Single Flute Spiral End Mill

This offering of End Mills for Plastics - Square Upcut - Single Flute results in twice the material removal with improved finish over standard end mills. The high rake, high relief design of this tool produces a sharper edge for improved shearing action while transferring heat into the chip.

Why Use a Single Flute End Mill?

The reason we use fewer flutes in some materials has to do with the behavior of chips in those materials.  Simply put, aluminum creates bigger chips, all other things being equal.  This has to do with the way the material curls as well as other factors.  The space created by the flutes of the endmill is where the chips have to go as they’re being cut.  If there is not enough space relative to the volume of the chips, you’re going to have problems and may wind up with a broken cutter.  Therefore, we typically dial back the number of flutes for aluminum because it creates a larger volume of flute space to carry away the oversized chips.

This productivity issue, where more flutes can be more productive, has to do with two factors: Material Removal Rates (MRR) and Surface Finish.  One matters more to roughing (MRR) and one obviously matters more to your finish passes.  This all has to do with what I’ll call the Tyranny of Surface Speed.

Let’s put aside this issue of flutes and talk about single point cutting on a lathe.  It’s so simply, it helps shed light on what’s going on.  For every material there is a best surface speed that the manufacturer recommends.   This recommendation largely has to do with spinning to the (or workpiece on the lathe) as fast as possible without harming tool life.  The limiting factor is heat.  Tungsten Carbide will tolerate a lot more heat than High Speed Steel before it begins to soften.  If the material your tool is made of softens, the tool’s sharp edge quickly dulls and your tool life is shot.  So, you want the tool to handle as much heat as possible, and that’s why Carbide can often beat HSS.  Since we can’t beat the speed limit, we have to fiddle with other factors when we’re up against it.

So, let’s assume you’re running the tool flat out in terms of Surface Speed.  Any faster and it gets too hot, dulls, and it is finished.  How else do we get higher material removal rates?  The answer is we space out more cutting edges (flutes) around the circumference of the cutter so that as the cutter is spinning, we get a lot more bites (chips) of the material.  It’s now pretty obvious.  At a given surface speed, a 4 flute endmill can take 4 cuts at a given chip load (chip thickness) while a 2 flute only takes half as many.  So the 4 flute might have 2x the MRR.  This is why we see cutters with many flutes become popular in challenging materials that only allow fairly slow surface speeds.  That’s how we get productivity back.
