Been having some issues with insert V bit tips specifically some 60 degree amana inserts we run a bit. We have occasion to run some very small text which requires a true V bit not something like an engraver with a .005 tip. We have all the Amana insert V bits but run a 60 degree insert and a 60 degree solid most often. The insert tips break off like nothing no matter how shallow or how slow you go. This is all in wood, Walnut, Hard Maple, whatever. In very short order (like perhaps 50 small characters (perhaps 1/2" tall) you've got a .005 flat bottom bit because the tip is gone. You can barely see that its gone with magnification but it is in fact gone.
Paying 25 bucks a whack for an insert that loses its tip that fast is not fun.
Any of you using something different?
Im pretty much convinced to stick with solid or brazed tooling and keep sending them out because at least the tip stays pretty much there to a V point until its so dull its just rubbing a fuzzy bottom in the text but when the insert tip is gone youve still got an insert that 98% of the insert has never seen its first wood fiber and its roached.
I have run insanely slow feeds and played around with the speeds but no luck.
