    I use these a lot. They work great but with a long small diameter cutter like this it is not too difficult to break them. These are great quality and value.

    The end mill has a great price point and high quality.

    Broke in first 4 min .1 DOC 45 in/min speed. I bought 2 because they were same day shipping and needed them ASAP and I was afraid one would break. Ran the second bit at .09 ODC and 40 in/min and it worked fine.

    This bit was clean cutting and long enough for my 3/4” thick material (wood) on my XCarve!

    Spe is one of my favorite bits. They really last a long time and they stay sharp for a long time. Ive only broke a few but its usually because of user error

    Really like the length and reach however cutting even at slow feeds and shallow doc seemed to much. But just seems dull compared to other brands I’ve used.

    This is a great bit for cnc use. Cuts great and the extra long reach is exactly what was needed. Will definitely buy again

    Broke under normal carving parameters.

    I ran this bit on my cnc machine at 60 inches per minute, pass depth of 0.1 inch spindle speed at 10,000 and carving oak 1/2 plywood it broke within a couple minutes. I didnt expect that.

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
