1/2" AVEL3 Extended Reach RampMill
The king of constant engagement toolpaths in aluminum, the AV3 RampMill is a must have tool in your magazine. Not only are they capable of ramping at 17°, but they are very free cutting, and make extra compact chips due to the chip breakers. If you see any other cutters similar to the AV3 on the market, they've likely copied SwiftCarb's homework. Often imitated, never duplicated.
If you're looking for the AV3 flute geometry without the ramping geometry, along with an array of corner radius options, check out the AR3.
