Projetado para fresamento onde a remoção de cavacos para baixo, rigidez da ferramenta, longa vida útil e acabamento de alta qualidade são desejados. Use para madeira natural e compostos de madeira.

Nenhuma unidade disponível
Flauta dupla, ângulo de 30 graus. Quando operadas no sentido anti-horário (corte à direita), as ferramentas estriadas espirais evacuam os cavacos para cima e para fora do corte para reduzir o entupimento. As hastes redondas permitem o uso com uma ampla variedade de sistemas de porta-ferramentas. As ferramentas não revestidas apresentam apenas o substrato base sem nenhum tratamento ou revestimento adicional e são adequadas para uma ampla gama de aplicações. As ferramentas sólidas de metal duro oferecem vida útil longa e velocidades de corte mais rápidas do que outros substratos, mas são mais frágeis e devem ser usadas com sistemas de porta-ferramentas rígidos.

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.
