Manufactured by KEUE, this SUNR0012M16U CNC internal threading tool holder adopts a 30° trapezoidal U-shaped cutting design. Engineered for precision internal threading operations, it matches 16UID indexable inserts and supports both 4.0TR and 5.0TR thread pitches for flexible production demands.
Its U-shaped flute structure effectively guides smooth chip discharge and suppresses cutting vibration, ensuring stable performance even in deep bore threading. The precision-machined trapezoidal insert seat delivers tight blade positioning accuracy, preserving standard thread profile and fine workpiece surface finish.
Produced in Mainland China under strict quality control, it fully supports OEM customization for tailored specifications. Compatible with all standard CNC lathes, it delivers consistent batch-to-batch quality at competitive cost, suitable for automotive, hardware and general machinery manufacturing.
