One of my first paying jobs is to cut this 1.5" thick bamboo plywood into nice shapes. I had a ½” endmill that had a 3” cutting length I got for mortises. a 2f carbide made in usa I think it was a putnum brand. Well on the test cuts in ½ particle board some of the holes on the last plunge I would get a twang or think that made the z springs twang and the hole would be a bit chipped. The big sounded noisy just running. So I was think just too much flex and found a 4f 1/2 “ same brand and finished cutting the test piece. But as soon as the bit touched the bamboo it was chattering and smoking. The feed was 100ipm and about 12000 rpms. Later I was thinking with 4f the feed was too fast. But I was only removing about ¼”
Ok so I take it I need to buy the right bit Monday (G)
