Grooving Toolholders GND Series - Features & Benefits


High rigid design reduces vibration by as much as 30% over conventional types


Grooving General Feed Type First choice for grooving Low Feed Type For low-feed chip control GL GL Type Chipbreaker Application Specific For R grooving RG RG Type Chipbreaker


Profiling General Feed Type Perfect for profiling RG RG Type Chipbreaker


If chips are long when using GG and GL type chipbreakers for grooving, chip control can be improved by using MG or ML type chipbreakers. 2
