TungCut – Bush Stopper – AH725


- Excellent fracture resistance!: Tungaloy’s DGM chipbreaker with tough cutting edge provides excellent fracture resistance and hence tool life is stable, unlike the Competitor tool which has sudden fracture due to the poor chipping resistance of cutting edge.

- High wear resistance!: The tool life of DGM is improved to 2.3 times longer than competitor, due to the incredible wear resistance of AH725 grade.
