Now, does this make sense...?
Given a router bit with 3 cutting edges on it...
It spins at thousands of RPM...
The distance between each cutter has to be insignificant at that speed... yes?
If the 1st cutter is sharp, isn't it doing all of the cutting and the rest merely keep the whole thing in balance spinning smoothly... while the the other 2 cutters are just spinning, doing nothing!?
Could it be that it's just a 'gimmick' to sell more product?
(do those extra blades really cut any hair or just scrape your skin for blood?!
)
