A Carbide Internal ID (Inside Diameter) Micro Grooving Tool is a precision cutting tool designed for creating extremely small grooves, channels, or undercuts on the interior surfaces of holes or bores in machined components. These tools are engineered for high-precision applications where tight tolerances and fine surface finishes are critical.

• Material: Made from tungsten carbide for superior hardness, wear resistance, and rigidity.
• Cutting Width: Typically ranges from 0.1mm to 2mm (some custom tools go as small as 0.05mm).
• Applications: Used in CNC lathes, Swiss-type machines, or precision boring mills.
• Geometry: Features specialized edge preparation (sharp or honed) for clean cuts in various materials.
• Coatings: Often coated with TiAlN, DLC, or diamond for enhanced tool life in specific materials.

• Medical Devices: Implant grooves, surgical tool channels.
• Aerospace: Locking wire grooves, fuel injector slots.
• Automotive: Piston ring grooves, sensor housings.
• Electronics: Micro-fluidic channels, connector slots.
• Watchmaking: Precision gear and bearing grooves.

1. Superior Chip Evacuation
   • Problem: Micro grooves trap chips, causing recutting, tool wear, or workpiece damage.
   • Solution: High-pressure coolant (70+ bar) flushes chips out efficiently.
   • Example: In stainless steel, coolant-through tools reduce chip welding by 80%.
2. Extended Tool Life
   • Heat Reduction: Direct coolant flow lowers cutting temperatures by 30-50%.
   • Data: Tools with coolant last 3-5× longer in titanium vs. non-coolant versions.
3. Improved Surface Finish
   • Coolant prevents built-up edge (BUE), enabling Ra
   • Critical for:
     • Medical implants (Ti6Al4V)
     • Aerospace seal grooves
4. Deep Hole Capability
   • Coolant pressure maintains performance at 8-10×D reach (vs. 4-5×D without coolant).
   • Application: Fuel injector grooves in Ø3mm holes at 20mm depth.
5. Process Reliability
   • Reduces manual intervention (no frequent pecking required).
   • Case Study: Automotive O-ring groove production saw 60% fewer rejects after switching to coolant-through tools.
