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
