4.1/5

Conçu pour le fraisage où l'élimination des copeaux vers le bas, la rigidité de l'outil, une longue durée de vie et une finition de haute qualité sont souhaitées. Utilisation pour le bois naturel et les composites de bois.

Aucune unité disponible
Double flûte, angle de 30 degrés. Lorsqu'ils fonctionnent dans le sens inverse des aiguilles d'une montre (coupe à droite), les outils à cannelures en spirale évacuent les copeaux vers le haut et hors de la coupe pour réduire le colmatage. Les tiges rondes permettent une utilisation avec une grande variété de systèmes de porte-outils. Les outils non revêtus ne comportent que le substrat de base sans aucun traitement ou revêtement supplémentaire et conviennent à une large gamme d'applications. Les outils en carbure monobloc offrent une longue durée de vie et des vitesses de coupe plus rapides que les autres substrats, mais sont plus fragiles et doivent être utilisés avec des systèmes de porte-outils rigides.

Nice Clean Razor Sharp Cuts, And A Good Value
My how using the correct bit for the application is so life changing. I hate to sound so dramatic, but learning to use a CNC router, to really learn to use it to all it's benefits takes a very long time, especially when you are doing it yourself (and with help online sometimes). For many years, I never really thought much of changing my end mill to a down-cut type of bit. Then Christmas came and I had a sign to do for a customer and had used pine as the substrate. As any of you know, pine is rather stringy and can present problems when milling intricate cuts. I looked at my test piece and thought that I would be spending a long time making it look good. I was cutting pockets for letters to fit into and the surface had to look good. Then suddenly I thought about the down-cut bit and decided to order one. I guess it's not my fault I hadn't used them before as most stuff I was don't really didn't need it, but this did. I got the new bit, and ran the test again. Night and day! The upper part of the pine, the surface that would be displayed was sharp and clean and I was as happy as a clam, (you got me too. I really don't know why a clam would be happy but I couldn't think of anything else). Anyway, chalk this up to experience and I hope this might help someone else with the same issue.

Works great for milling wood blocks for my high school manufacturing class. The down cut makes a lot more dust but gives a very clean finished product with little to no need for finish sanding.

sharp cutter
The bit was good and sharp - cuts well. Downward spiral avoids fuzzing and tearing of wood. Would be nice if it had a clear tube cover but it didn't.
