GER GEL-D series | Precision Internal Grooving Insert (W 1.0-4.0mm)

ZANHO GER/GEL-D series: Single-sided precision internal grooving inserts optimized for closed-bore machining. Featuring the specialized D-type chipbreaker, it enhances chip curling and evacuation, allowing for relatively higher feed rates in small diameters. Available in Right-hand (GER) and Left-hand (GEL) designations with widths from 1.00mm up to 4.00mm. Ideal for high-stability slotting and profiling in steel and alloys.

Technical Advantages

Optimized for Higher Feed Rates: The D-type geometry is engineered to handle increased feed conditions while maintaining superior chip control in closed internal environments.
D-Type Specialized Chipbreaker: Reinforced chip curling geometry significantly reduces the risk of chip packing and accumulation in deep, narrow bores.
Enhanced Edge Toughness: Precision passivated (honed) cutting edges provide high resistance against breakdown and impact under unstable machining conditions.
Full Radius (DR) Availability: Comprehensive range of DR-series Full Radius models (up to R=2.00) for specialized profile grooving and heavy-duty contouring.
Exceptional Stability: Standardized ød (3.40mm) and H (5.05mm) dimensions ensure secure clamping and maximum process safety in CNC lathes.
