Flaut dublu, unghi de 30 de grade. Când sunt rulate în sens invers acelor de ceasornic (tăiat pe dreapta), sculele cu caneluri spiralate evacuează așchiile în sus și în afara tăieturii pentru a reduce înfundarea. Tijele rotunde permit utilizarea cu o mare varietate de sisteme de fixare a sculelor. Uneltele neacoperite au doar substratul de bază, fără tratament suplimentar sau acoperiri și sunt potrivite pentru o gamă largă de aplicații. Sculele din carbură solidă oferă o durată lungă de viață a sculei și viteze de așchiere mai mari decât alte substraturi, dar sunt mai fragile și trebuie utilizate cu sisteme rigide de fixare a sculelor.

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.
