GARR TOOL Milling Guide for Aluminum
(Machining Centers with Mid-Range HP/Torque)

Series 142M/143M/A3 End Mills

NOTES: Climb milling recommended for best finish TECHNICAL
Contact your OEM for your machine’s optimal running parameters

TECHNICAL
CAT 50 Taper holders are recommended for 3/4" and 1" diameter end mills
In controlled slotting tests, 4000 SFM, 1% diameter Chipload Per Tooth and 50% of Dia. axial depth were obtained
In cases for tools with slower SFM (M/Min.), reference Series 242M/842M
For CAT 40 machines using tools over 5/8" diameter, speeds and feeds may need to be reduced by as much as 50%
