Double flute Straight bit

In cutting edges and the shortest overall length that will reach the required cut depth. Excessive length intensifies deflection and vibration, which degrade cut quality and lead to tool breakage.
Use a two-flute bit where fine finish is paramount. Two flutes balance the bit, eliminating vibration that degrades the cut finish.
Two cuts per revolution yield a smooth surface, but feed rate is slightly reduced.

To use router bits safely (and to get the best results from your router), the router bits need to be installed properly into the router's collet. Improper installation of your bits can cause excessive chatter and could increase the likelihood that the bits will break when in use.
First of all, before beginning any routing operation, check your bits to make sure that they are clean, relatively free of pitch, and most of all, sharp. If the bit is dull, chipped, is excessively burned or has any other defect, it should be sharpened or replaced before use.
