Progettato per la fresatura dove si desidera rimozione del truciolo verso il basso, rigidità dell'utensile, lunga durata e finitura di alta qualità. Utilizzare per legno naturale e composti di legno.

Prodotto non disponibile
Doppia scanalatura, angolo di 30 gradi. Quando vengono eseguiti in senso antiorario (taglio a destra), gli utensili scanalati a spirale evacuano i trucioli verso l'alto e fuori dal taglio per ridurre l'intasamento. Gli steli rotondi consentono l'uso con un'ampia varietà di sistemi portautensili. Gli utensili non rivestiti presentano solo il substrato di base senza alcun trattamento o rivestimento aggiuntivo e sono adatti per un'ampia gamma di applicazioni. Gli utensili in metallo duro integrale offrono una lunga durata dell'utensile e velocità di taglio più elevate rispetto ad altri substrati, ma sono più fragili e devono essere utilizzati con sistemi portautensili rigidi.

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.

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.
