Carbide Internal ID Micro Custom Grooving Tool

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.

Technical Parameters
Parameter Specification Custom Options
Tool Type Solid carbide micro grooving/boring combo Reduced shank, extended reach
Cutting Diameter 0.3-3.0mm (standard) Down to 0.1mm (custom)
Groove Width 0.1-2.0mm Tapered/radial profiles
Reach (L/D) 5×D (standard), up to 10×D (custom) Ultra-deep 15×D versions
Tolerance ±0.005mm (standard), ±0.002mm (high-precision)
Coatings TiAlN, AlCrN, DLC, Diamond-like Medical-grade polished surfaces
Shank Options 3mm, 4mm, 6mm Custom diameters/lengths
Design Advantages
  • Monolithic Carbide Construction: Zero deflection at L/D ratios up to 10:1 with 5× longer tool life vs. brazed tools in hardened steels (HRC 60+)
  • Dual-Function Geometry: Combines grooving + boring in single operation with ground clearance angles (2°-5°) for internal relief
  • Chipbreaker Flute Designs: Optimized for micro-chip evacuation (critical in <1mm grooves) with helix angles 30°-45° for material-specific performance
  • Coolant Optimization: Through-tool coolant ports (Ø0.3-0.8mm) with 80+ bar pressure capability for deep holes
  • Custom Edge Preps: Honed edges (0.01mm radius) for brittle materials or 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
