Whiteside Router Bits 2016 Bearing Review

Through trial and error I found that these router bits are a game changer... The bearings enable a consistently smooth cut, and the precision of the bit is unbeatable for the price. They are easy to handle and slot easily into my router, facilitating fast and efficient cuts. The only downside is the limited lifespan, although this is also to be expected from any cutting tool. Overall, highly recommended for both DIY enthusiasts and professionals..

I use this nozzle for the speaker cabinet flared terminals. If you want to use it to expand ports and use a handheld router like me (PORTER-CABLE 893PK 2 -1/4HP) you need to make a spacer. The diameter of this cutter is too large for the normal acrylic guide of the router. The brace also lifts the blade off the wood, creating a smooth, flared transition rather than the "table edge" it was designed for.
