Carbide Internal ID Micro Custom Grooving Tool Reduced Shank End Mill

Introduction:

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.

Features:

Critical Design Advantages

1. 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+)

1. Dual-Function Geometry

   • Combines grooving + boring in single operation

   • Ground clearance angles (2°–5°) for internal relief

1. Chipbreaker Flute Designs

   • Optimized for micro-chip evacuation (critical in <1mm grooves)

   • Helix angles 30°–45° for material-specific performance

1. Coolant Optimization

   • Through-tool coolant ports (Ø0.3–0.8mm)

   • 80+ bar pressure capability for deep holes

1. Custom Edge Preps

   • Honed edges (0.01mm radius) for brittle materials

   • Sharp edges (R<0.005mm) for non-ferrous metals

Specialty Applications

1.Medical Implants

• • • Bone screw internal channels (Ø0.8×10mm deep)

    • Dental abutment retention grooves

2.Aerospace Components

• • • Fuel injector spiral grooves (Ø1.5mm)

    • Turbine blade cooling holes (Inconel)

3.Micro-Fluidics

• • • Lab-on-chip capillary networks

    • Drug delivery nozzle geometries

4.Precision Engineering

• • • Watch movement oil reservoirs

    • Optical fiber alignment features
