NEWDeep grooving and parting off tools
Tungaloy Report No. 424-E
Highly rigid self-clamping tools that provide remarkable tool life
2
Suitable for various grooving operations
Innovative insert with long tool life
Exceptional chip evacuation
The rigid clamping system creates highly productive external, face and internal grooving as well as parting.
Conventional clamping system(Clipped type)
➀ Traversing is not recommended
➁ The upper clamp prevents efficient chip flow
➀ High clamping rigidity reduces insert wear and edge chipping. It also makes traversing possible
➁ Smooth chip fl ow and evacuation due to no-clamp structure
ETX typeExternal grooving

Face grooving and traversing
Parting off
Internal grooving

Easy indexing and high rigidity
Self-clamping system(Inserted type)
One insert type can cover a wide variety of grooving operations!
