IMCO - 2017 Comprehensive End Mill Catalog

E13 AlTiN
truCORE 30°
For general machining in a wide range of materials. The E13 offers
a combination of strong cutting edges with increased flute spacing
in a general-purpose tool design. Best for roughing and finishing in
slots and pockets and in gummy materials. The AlTiN coating offers
superior heat resistance and hardness for increased tool life.

TOOL TIP
Aim For a Chip-Free Cutting Zone.
The proper location and volume of flood coolant are essential for a
successful cut. Coolant plays a very important part in chip evacuation,
especially when machining in a pocket or closed area. But simply
blasting a large amount of coolant at the end mill isn’t the most effective
way to flush chips from the cutting zone. In fact, failure to direct the
coolant properly increases the risk of re-cutting chips, causing tool
damage and premature wear.
As this series of photos demonstrates, the most productive way to flush
chips out of a pocket is to direct the coolant to the bottom of the cut. This
allows the coolant to rebound off the tool and part floor, lifting the chips
out and away from the tool’s cutting edges
Poor
Poor
Coolant flow is perpendicular
to the end mill, flowing past
the end mill without hitting
it directly. This will not
evacuate the chips from the
flutes sufficiently or provide
proper cooling to the cutting
edges.
Coolant flow is hitting the
end mill nicely, but it is
perpendicular to it. This will
cool the end mill but will not
lift and flush the chips out
of the cutting zone.
