■ Precautions when Using Wiper Inserts

When using CNGA Type / CCGW Type / WNGA Type Wiper Inserts

Use a holder with a cutting angle of 95°. Machining program modification is required. CNGA Type/CCGW Type/WNGA Type wiper inserts do not comply with the ISO standard. Correct the cutting edge position (tool offset) as explained on the right.
