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

Series 242M/842M/A3 End Mills

TECHNICAL NOTES: Climb milling recommended for best finish

Contact your OEM for your machine’s optimal running parameters
Figures shown are based on 6061 / 7075
CAT 50 Taper holders are recommended for 3/4" and 1" diameter end mills
For CAT 40 machines using tools over 5/8" diameter, speeds and feeds may need to be reduced by as much as 50%
