Description

MGNVR/L Internal Grooving Tool Holder with IC, Internal Grooving Boring Bar

Master demanding internal grooving operations with maximum process reliability using the MGNVR/L internal grooving holder with integrated through-coolant (IKZ). Especially when machining internal grooves for retaining rings (circlips), O-rings, or seals, chip congestion and heat buildup inside the bore are the most common causes of tool failure. This tool overcomes these challenges through its innovative Jetstream technology: the coolant jet is directed through the shank straight to the cutting zone and the chip surface of the insert.

The result is controlled chip breaking and reliable chip evacuation from the bore, even in deep grooves or when machining difficult-to-cut materials. The stable clamping system is compatible with the widely used and economical MGMN and MGGN grooving inserts. Whether you are machining precision grooves according to DIN 471/472 or turning complex internal profiles – the rigid shank design minimizes vibrations and ensures excellent surface finishes. Increase your cutting performance and tool life with a holder designed specifically for high-performance machining.

Scope of delivery: MGNVR/L holder (without insert) including screw and wrench.

Nutze den Halter zum Innenstechen und für Innennuten. Die Innenkühlung ist gerade bei tiefen Nuten wichtig und funktioniert hier einwandfrei.
