You don’t want to be out of commission waiting for your dull router bits to be sharpened. That’s why Amana Tool’s created the new In-Tech series insert router bits. They never need to be sharpened because you just replace the cutter when the old one dulls.

Amana manufacturers the knives for the In-Tech bits out of tungsten carbide, so you can use the bits on a wide variety of materials like softwoods, hardwoods, MDF, and chipboard. They claim the bits (not the cutters, of course) last four times as long as other brazed router bits, and the cutting accuracy is consistent over the life of the knife.

Amana makes nine 1/4″ shank bits with replaceable cutters. The nine bits include a 1/4″ radius bit, a 1/4″ cove bit, an Ogee bit, a 1/2″ rabbet bit, a flush trimming bit, a 2-in-1 corner round and bevel trimming bit, a V-groove bit, a 1/4″ radius core box bit, and a 1/2″ straight plunge bit.

Amana priced the bits comparably to other companies’ brazed router bits. The bits cost anywhere from $17 to $53 and replacement cutters run $6 to $15 in pairs.

    About time! We’ve been using indexing cutters in shapers and metalworking for decades, and they really pay off!

  2. Shopmonger says:

    Yes these are the way to go, if you do a lot of use on one bit. Plus can be sharpened in a lot of cases

  3. Bill says:

    Quarter-inch shanks don’t cut it.

    I agree that 1/2 inch shanks produce less vibration and generall better cuts – but most of the bits shown are for light trimming operations. You could see mounting some of these in you Colt or Betterly trimmers – where 1/4 shank is what you’ve got.

    Gak! The whole idea of sharp blades or screws that could *potentially* come flying off at light speed kinda dampens my enthusiasm. How about you guys try ’em first, then let us know how it goes.

    Don’t jointers use removable blades similar to these?
