End mill |
|
| End mills
are those tools which have cutting teeth at one end, as well as on the
sides. The words end mill are generally used to refer to flat bottomed
cutters, but also include rounded cutters (referred to as ball nosed)
and radius cutters (referred to as bull nose, or torus). They are
usually made from high speed steel or cemented carbide, and have one or
more flutes. They are the most common tool used in a vertical mill.
It must be noted that the
cutting flute does not go all the way to the centre, and thus can not
plunge into the work. Cutter must be fed into the side of the
work.

slot drill is just a 2-flute end mill used 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
