Being new to woodworking I have a question about router bits. For routing CF rod channels, Truss rodd channels, tenon channels, what is the best type of bit? Basically what are the differences and advantages/disadvantages of 1. Straight flutes 2. Downcut spiral 3. Upcut spiral. My 1/4 inch is dull and needs replacing/sharpening and I am curious what to replace it with. Currently I have a downcut spiral |

Im not hot on down cut or up cut router bits I like straight fluts. I do suggest 3 flut vs 2 flut. They run truer and cut cleaner |

Do any of you sharpen your bits??? Do you buy carbide vs HSS??? |

I strop my bits on leather regularly but I dont sharpen because you can change the diameter pretty quickly. this means I buy a new bit when it is not cutting efficiently. Carbide only |

Only carbide bits and I sharpen with a small credit card size, fine grit diamond plate. You only need touchup the flat of the cutter. Cheers Kim |

Andy, this single flute bit is ideal for the Allied truss rod slot. It cuts a slightly narrower groove than a double flute. Nice snug fit for Allied's rod. The bit I like: Ron |

I like downcut, two flute end mills. Carbide steel is good. Never tried HSS. I don't use them enough to worry about sharpening. I just replace them when they start getting dull. For wider cuts in a router I use garden variety carbide tipped router bits. |
