MB Internal Grooving Inserts

ZANHO MB series: Specialized "Comma-style" internal grooving inserts designed for extremely small bore diameters. Featuring a unique heteromorphic single-edge structure, these inserts minimize cutting resistance and optimize chip curling in closed environments (Dmin: 9.0mm - 20.0mm). Engineered for high-precision micro-bore slotting and profiling in steel and alloys with exceptional process stability and accuracy.

Description

Technical Advantages

  • Micro-Bore Comma Geometry: Specialized heteromorphic single-edge structure allows entry into extremely small bore diameters where conventional tools fail.
  • Closed-Space Chip Control: Rake surface optimized for confined internal spaces, ensuring reliable chip curling and preventing packing in deep holes.
  • Enhanced Edge Toughness: Precision passivated (honed) edges provide superior resistance against chipping under weak machine rigidity conditions.
  • Stable Positioning Structure: Engineered for high-repeatability clamping in MB-series internal grooving tool holders, ensuring consistent slot width precision.
  • Full Radius Availability: Complete range of Full Radius versions (R = W/2) for high-accuracy hydraulic and profiling applications.
