Endmills

- Tech Info

• RedLine 2 & 3-Fute, 45 Degree Helix Endmills are designed for high speed machining in Aluminum, Brass

and Bronze, and can be used for plunging, slotting and profiling in all non-ferrous materials.

• Aluminum, Brass, Bronze and other non-ferrous materials. These tools can be used for plunging, slotting

and profiling.

• The ZrN coated tools allow for higher speeds, better tool life with a low affinity for Aluminum.

• These High Performance tools can be found on pages 14 & 17.

NOTES: (1) Speeds and Feeds listed are estimated and will vary by application.

(2) Reduce Speeds by 20% when slotting.

(3) When exceeding 1/2 the end mill diameter while proﬁling, reduce feed rate by 25%.

(4) The use of Long and Extra Long Endmills require a reduction in feed by up to 50%.

(5) Optimum performance can be achieved when using coated & stub length tools.
