Whiteside RU1805 5 mm upcut spiral
1/4 in

When to choose it
The RU1805 makes a nominal 5 mm groove from a router with a quarter-inch collet. This combination is useful when the project dimensions are metric but the router accepts an imperial shank.
Check the width against the part you will fit. The upcut flute moves chips toward the router, and the 5 mm cutting diameter should be kept separate from the imperial shank size.
