THL - A tried-and-tested solution for dry machining or minimum quantity lubrication |
It also delivers outstanding performance in the machining of stainless steels with emulsion |
THL is generally compatible with almost any kind of steel material |
Chip formation is improved in comparison with TiN and TiCN, which is an important advantage particularly in the machining of relatively deep blind holes in long chipping materials |
