What end mill should you use for aluminum at high RPM?
For high-RPM, high-horsepower aluminum machining, RobbJack's FMHV is a solid carbide end mill built for ultra-high-velocity cutting: its patented Mirror Edge™ geometry dampens chatter so it runs more than 450% deeper than the stability lobes predict, and a 1" FMHV has removed 604 cubic inches of aluminum a minute. It comes in 2,600+ inch (FMHV) and metric (MFMHV) sizes, with chip breaker, thru-coolant and DLC options — DLC applied by Crystallume PVD. For general aluminum work on standard machines, RobbJack's AL3 series is the broad choice.
FMHV is our highest-velocity aluminum platform. The patented Mirror Edge geometry dampens vibration so you can take deeper Z-depths the deeper you go — more than 450% deeper than the stability lobes predict.
On high-HP, high-RPM machines that translates into staggering removal rates — a 1" tool clearing 604 cubic inches a minute — and customers reporting 3–4× the metal-removal of what they ran before.
Why it wins
- Patented Mirror Edge™ geometry for chatter-free deep cuts.
- Anti-pull-out shank technology holds the tool under the most aggressive loads.
- Thru-coolant holes and DLC coating available.
- Scales with your spindle — FMHV will max out the HP/kW of any machine you put it on.
