Can anyone recommend a decent Wiper Insert. We are turning from 12 down to 5mm, tapered with two shoulders, for a length of 27mm,
material is 17-4 H1100, hardness tested at about 34 HRc. Fillet requirement at the shoulders is .2mm other than that pretty smooth sailing.
Chips are a bit stringy but would like to improve the surface finish.
Any comments much appreciated.
