Carbide Internal ID Micro Custom Grooving Tool Reduced Shank End Mill

A carbide internal ID micro custom grooving tool for small hole boring is a precision-engineered cutting tool designed for creating intricate grooves, undercuts, or channels inside tiny bores (typically Ø0.5-5mm) with extreme accuracy. These tools combine grooving and boring capabilities in one rigid carbide body for complex internal machining.

Design Advantages
Monolithic Carbide Construction
  • Zero deflection at L/D ratios up to 10:1
  • 5× longer tool life vs. brazed tools in hardened steels (HRC 60+)
Dual-Function Geometry
  • Combines grooving + boring in single operation
  • Ground clearance angles (2°-5°) for internal relief
Chipbreaker Flute Designs
  • Optimized for micro-chip evacuation (critical in <1mm grooves)
  • Helix angles 30°-45° for material-specific performance
Coolant Optimization
  • Through-tool coolant ports (Ø0.3-0.8mm)
  • 80+ bar pressure capability for deep holes
Custom Edge Preps
  • Honed edges (0.01mm radius) for brittle materials
  • Sharp edges (R<0.005mm) for non-ferrous metals
Specialty Applications
Medical Implants
  • Bone screw internal channels (Ø0.8×10mm deep)
  • Dental abutment retention grooves
Aerospace Components
  • Fuel injector spiral grooves (Ø1.5mm)
  • Turbine blade cooling holes (Inconel)
Micro-Fluidics
  • Lab-on-chip capillary networks
  • Drug delivery nozzle geometries
Precision Engineering
  • Watch movement oil reservoirs
  • Optical fiber alignment features
