Router Bit 1/4 or 1/2 inch?

[namluke 1]

Hi, 

I want to router a groove in some hardwood (Ash or Oak) 20mm wide and 10mm deep.

Am i right in thinking using a half inch 20mm router cutter will have less vibration resulting in a cleaner cut?

I have the bit in a 1/4 inch but just wondering if i should up to 1/2 or will it not really make a difference ?

 

Many Thanks

Luke

Larger shank whenever possible.  You are correct in that a larger shank bit of the same type will yield a better result in most situations.  If the groove is for joinery that will not show I would be less concerned.  If it is an visual detail I would get the 1/2" bit.

Perfect,  ill go for the 1/2 bit.
