Description of LMT Onsrud 63 610 Diameter without Coating
Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Single flute, 22 degree angle.
Works very well with the Sintra board, cuts 6mm with no problems. I've found that lowering the RPM to 11,000 and 90 RPM gives the best cut with little to no cleaning.
DIY CNC Bit. Cuts aluminum better than any of my other end mills. It cuts well and makes deep cuts. It would be great if they sold more of their vinyl cutters on Revain. A note: I clean my end mills and parts with isopropyl alcohol and the end mill gets stained after soaking it overnight. Looks weird, but still cuts well.
I just got some parts ready for my aluminum 3D printer and everything was perfect. Walked very slowly to see what he could do. I started with contours at 50 mm per minute, then it went up to 100 mm per minute without any problems. Plunging into the holes was done at a speed of 40mm per minute without vibration. was very impressed with this beat. must get more for different cuts
