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
- 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
