    I ordered this for use in my CNC router. Had a production run of wooden pen cases to cut out (walnut and maple) and needed to order a new bit to avoid tearout. Took a chance on this one because the price was low. I wasnt expecting much, but its still very sharp after cutting for 12+ hours. Might be just a hair bigger than 1/4, as my 1/4 indexing pins were a little loose in the positioning holes that this bit drilled. Regardless, Ill order more of these for future jobs for sure. Very happy with the cut quality and tool life.

    ESTA FUE UNA REPOSICIÓN DEL PEDIDO ORIGINAL YA QUE EL PRIMERO SE EXTRAVIÓ Y AMAZON AL DETECTAR EL PROBLEMA INMEDIATAMENTE ME ENVIÓ DE NUEVO EL PRODUCTO QUE LLEGÓ RAPIDÍSIMO. PROBÉ UNA EN MI FRESADORA Y LOS CORTES FUERON GENIALES. LO RECOMIENDO

    This was purchased for cutting a radius through laminate plastic glued to MDF board used for shop made table saw miter sled. The down spiral cut left a very smooth, clean edge in the thin plastic, exactly as desired. It also left a clean, smooth edge on the MDF and a plastic liner glued to the underside as the surface contacting the table saw. If interested, this highly accurate miter build is illustrated by the designer on YouTube. Search for Making a Super Accurate Miter Gauge.

    Spe and amana bits are all that I use now. Great quality on these bits! This is the one I use for roughing out my cnc parts

    I bought this end mill for use in my cnc machine exclusively for wood milling. I use mainly bits from amana tools but occasional buy an off brand bit to try out and was pleased with how this bit has continued to cut decently after many hours. I dont think it cuts as clean as a high end bit, but its so close that Ill be buying more of these in the future.

    First time user of this product. Seems to work fine for my applications cutting wood and foam. Very sharp so use caution handling with bare hands.

Difference Between Down-Cut,UP-Cut and Compression Bit

DOWN CUTDOWN CUT

UP CUTUP CUT

Down-Cut Bit

  • Down-cut bit leaves a clean top edge but a rough bottom edge
  • It is great for cutting shallow dados, rabbets, and visible slots. When cutting dados or grooves with a down cut bit, be sure to slow the feed rate to allow more time for chip removal

UP-Cut Bit

  • Up-cut bit leaves a smooth bottom edge but a rough top edge
  • The up cut is better at evacuating chips, Ideal for mortise and tenons, grooving, slotting or routing deep blind holes. It performs faster cutting while pulling the chips up.

Compression Bit

  • Compression bit cut both top and bottom cleanly, Its spiral action pulls both sides into the center of the bit where it ejects out of the side.
  • Through cuts in harwoods, softwoods, plywood, melamine, and other veneers
