Besides, most end mills are designed to be centre-cutting, meaning they can plunge into the material as well and making them far more versatile than drill bits. This article aims at explaining the basics of end mill science while answering the simple question you might have: which end mill should I use on my CNC machine? Three major factors will influence your choice  If it sticks out too far and you work it too demanding, the cutting forces will make it bend, which is what is called “tool deflection.” Tool deflection can actually be very problematic since it induces: chatter, which are vibrations caused by the relative movement between the workpiece and the cutting tool  So when the end mill is cutting down in a hole or a slot, its flutes provide a crucial path for chips to escape. A slot drill is just a 2-flute end mill used Slot Cutting End Mill Project for cutting a slot, as per the name, more clearance for the chips to come out of the back without clogging then, there'll be one flute cuts over centre so it can be used to plunge cut small distances too, to start slots in the middle of material. However, it's a slow process so any time you can you're better off using an endmill. But it depends on your machine, I used to do slots mid-plate just by ramping down with a 5 flute cutter, much faster.

Machining a groove or slot, often called full slotting. Oct 29,  · For slotting you'll want 2 flute. For a less-than-rigid setup you'll want high speed steel. Ideally the cutter is about smaller than the slot so you can finish per side. You might want even more rough stock allowance than that if there is much play in your setup.
