    Work great cutting 1 inch wood on my cnc

    I dont know what these reviews are about having issues with this bit. Ive been using them cutting intricate dovetails on cnc with both vertical and horizontal orientation on my cnc through 4/4 milled exotic hardwood. I obviously need this size bit to handle that. Now I go slow and take about 8 to 10 passes over that stock, but it works wonderfully. Im on my 3rd bit, because Id say I average about 4 dovetail boxes a week, over 6 months. My first bit is rough, but hasnt broke, and I still use it for roughing or test pieces cuts, and my newest one for the higher exotic exotics. So it cant be that I got lucky with a good lot of bits since Ive ordered more over time. Only thing that makes sense to me and from what I see from other reviews is they dont understand feeds, speeds, and depth per cut. Simple if you understand tha you wont have problems

    Broke immediately. Super flimsy!!! Get a descent brand because these are junk

    Sometimes you need to cut thicker wood. This bit helps with that task. I don’t know about the longevity yet.

    Liked the length , able to cut 3/4 material with several passes. The 1/4 inch shaft is far better than using adapters that somtimes slip

    I used this but in a two stage carving. It worked very well in the roughing stage and then followed by a 60° v-bit for the rest of the details. I highly recommend.

    After three uses this bit broke in half. I was using it on a routine cut and it broke in half. I am not satisfied with this bit

    Works great but gets dull fast

    In middle of cut with cnc in hard wood the bit broke where it makes the transition from 1/4 to 1/16

    Im glad I went with the extra-long bit. The bit that comes with the inlay kit works well but limits you to 1/4 temples and limits your inlay depth. The longer bit allows you to use 1/2 thick templates and still cut a 1/4 deep inlay. 1/4 template allows you to get 3/4 inlays.

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

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
