This attachment was featured in a popular YouTube video demonstrating high speed aluminum cutting on the X-Carve CNC machine. Capable of increasing depth by more than 0.01" per pass. It's in very good condition and I'm surprised it hasn't broken yet.
Media could not be loaded. Wow! I love this end mill! Works great on my X Carve! Here are my speeds and feeds I used. I can't wait to cut more! I also posted a video here. Thanks Kodiak
This cutter works very well. I use it on a Chinese 3040 CNC router with a 400w spindle. With adaptive clearance, I got good results at 400mm/min in 0.5mm increments and a depth of cut of 3.125mm. A small amount of cutting fluid helps a lot and extends the life of the drill.
