Inserts are not included, giving you the freedom to choose inserts that match your material, groove width, and depth requirements. Robust clamping provides stable support, reducing tool chatter and improving groove dimensional accuracy and surface finish. Compatible with standard MGEHR external grooving inserts, simplifying setup and replacement. Durable tool holder designed for reliable performance in routine external grooving tasks. What makes it stand out Focused design for external grooving applications using the widely used MGEHR insert type. Clear specification of insert compatibility and hardness, supporting predictable, repeatable results. Applications and use scenarios External grooving on a cylindrical shaft in CNC turning to form a groove for seals or retaining rings. Grooving long or delicate workpieces where rigid tool support helps maintain groove accuracy and finish. Finishing external grooves on hydraulic piston rods or similar components requiring consistent groove dimensions. Notes Inserts are not included; MGEHR inserts separately to match your groove width and depth requirements.
