Make sure you use the correct tool paths these are designed to cut at deeper depths but you must use a more a conservative feed rate and make sure to ramp your cuts!40 ipm, 5mm per pass on plywood

Good router bit but delivery bad

The media could not be loaded. Cant complain a ver gd product but watch your fingers it is very sharp

Io che sono metalmeccanico e le frese le conosco bene... questa su legno va molto bene! perfetta.

Son de muy mala calidad para bricolaje esporádico, no se pueden comparar con unas de cmt o similar.

utilisé sur une défonceuse (excellente coupe rapidité d’exécution )

We are using a lot of these 4mm compression bits in our company. They are very good, very stable and the cut is super clean. We are using about 10 pieces a month.With the right Toolpath and direction it’s super easy to use. We are cutting upto 21mm MDF in one cut. In the pictures attached you can see a 16,4mm thick plywood with HPL on both sides, cutting HPl clean is a difficult task. All cuts are in one pass. This cutter does it easy. The nice effect of a compression bit is, you don’t need taps since the compressed wood is holding it very strong.I don’t know why people are giving such bad reviews so I thought I’ll make one authentic review. And to prove my position I’ve attached my machine so it’s not a hobby review.

Usada en una fresadora CNC para cortar madera con pasadas de 1mm y el acabado es bastante malo.Engancha bastante la madera a contrabeta dejando un acabado muy malo.Tengo otra parecida CMT y no hay color.No la recomiendo.
