This afternoon I used one of my flycutters for the first time. They seem to work allright. I have a cheesy little set of 3 different sizes from Busy Bee. They take a brazed carbide tool insert that may very well be a lathe cutting tool---it sets in a slot and has 2 small setscrews to hold it in place . I know that in order to use it I have to put my mill in reverse ---The rotation is exactly opposite of all my end mills, in order to cut on the face of the carbide. I am milling a peice of 3/4" square hotrolled to take it down to 0.625" thick. I seem to get good results at about 1100 RPM and a feed rate of .005" each pass. I hope this works out as a viable solution to cut down the thickness of material, as I have been using the ends of my 4 flute endmills to do this, and they are all getting dull on the ends.---the cutting tool in the flycutter, being carbide should last longer. any tips or suggestions, people?---Brian
