I am on the hunt for 1/4" shank bits, I need 1/32, 1/16 and 3/32" bits. I know I can get a reducing collet to use all these fine bits I have from Stewmac, but I'd really like to find them in the correct size for my lam trimmer. Thanks all |

Lance, not to hijack but on a related note, i heard through the branches that you have an overarm pin router, these small size bits you're looking for , is it for inlay purposes with your lam trimmer and overarm jig? Curious because i'm trying to come up with my home made design of an overarm router jig and would like to use my PC 7310 to inlay fretboards and headstocks, TIA! Serge Edit: oh and might as well ask for a pic of your nice set up if you please?  |

Thanks Lance, but would you still recommend a lam trimmer for inlaying?

Serge, I have two of the PC 7310 and they are great routers, I really haven't used my 310 yet, but as I said, its super smooth. Ill let ya know how I feel about it after I do a few rosettes

You could try Electric Tool Supply down off state street (1/16" is the smallest they usually stock in straight cut, and 1/8" in downcut so it may be a special order), or try Grainger over off Eisenhower for end mills instead of router bits. |

Thanks Dave! I found a place called American-Carbide I ordered a .030 and a .0625 from them, well see how they are. American Carbide |

Lance, why would you not just order the reduceing collet (1/4 to 1/8) from Stew Mac so you can run the 1/8 bits in your lam trimmer? I know that more mass is better but in these small bits it is probably not an issue, but the collet reducer may introduce more 'play' (you know, out of roundness  ) in the process.

Shane, I know that the reducer would probably work, but I fear the bit would be out of square. Small price to pay to get it all up and running the best possible way. |

Would these 1/4" shank small straight bits work on spruce? |

I bought some last year for my rosettes and they've worked just fine Anthony. |

Shane[/QUOTE] I'm not a big fan of 1/8" shafts. Actually, I'm sure it would be just fine for things such as shallow cuts in spruce for rosettes or for inlay, but most of my narrow cutting is for deeper things like saddle slots. In this case I feel the 1/8" shaft flexes too much and doesn't offer as clean of a cut. |

I've been using a couple of different 1/4" -> 1/8" reducers for running small bits (CNC inlay). I haven't been able to detect any ill effects or runout, and I've done several tests to make sure. If the reducers can stand up to CNC applications, they will work well for any kind of routing task. The ones I have appear lathe turned, so concentricity and runout should be negligible. Can't remember if they are Stew-Mac or another source. My preference is to always run the largest shank possible, but 1/32" endmills are so cheap and readily availble with 1/8" shanks, so I've been using those. Steve |

it is not clear whether the straight bits are plunging or not. if they are plunging then they should work in most situations. the advantage of a spiral bit which removes the chips from the cut is less heat and cleaner cuts. lance, i had a look at the linked site and did not find the bits you wantedcould you direct me. i would prefer not to use a reducing collar as well, even though i have never had a problem with it. |

Lance, I have ordered some of the larger bits from the same place in the past. They arrived pretty quickly, the quality seems good to me. Their prices are pretty good too. |

Lance, I could be wrong (happens often!) but it looks like those are 1/8" shafts. I couldn't where it said there but when I clicked to the long shaft micro end mills they do specify 1/8" shaft. Shane |
