1mm Cut Width Carbide Internal ID Micro Grooving Tool With Coolant Through Hole

Introduction:

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.

Features:

1.Material: Made from tungsten carbide for superior hardness, wear resistance, and rigidity.

2.Cutting Width: Typically ranges from 0.1mm to 2mm (some custom tools go as small as 0.05mm).

3.Applications: Used in CNC lathes, Swiss-type machines, or precision boring mills.

4.Geometry: Features specialized edge preparation (sharp or honed) for clean cuts in various materials.

5.Coatings: Often coated with TiAlN, DLC, or diamond for enhanced tool life in specific materials.

Specialty Applications

• 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.

Why choose Micro Grooving Tool with Coolant Through Hole?

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 < 0.4 µm finishes in aluminum.

• 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.
