Description
OSG Micro Carbide Drill – 20D Internal Coolant – IchAda Coated, 1.40 mm diameter, is a precision micro drilling tool designed for extreme-depth holes and tight tolerances. It’s ideal for engineers, machinists, and hobbyists who need reliable performance in challenging materials.
The 20D internal coolant design enhances chip removal and thermal control, while the IchAda coating adds hardness and wear resistance for high-speed machining and long runs.
- Internal Coolant for Superior Chip Removal: 20D internal coolant channels actively evacuate chips and control heat, maintaining hole accuracy and extending tool life during deep-hole drilling.
- IchAda Coating for Hardness and Wear Resistance: The IchAda coating delivers enhanced hardness and wear resistance, enabling higher speeds on tough materials while protecting the drill edge.
- Engineered for Extreme-Depth Drilling: Designed to deliver consistent diameter and straightness in very deep holes, supporting repeatable results in critical manufacturing tasks.
This combination of precision geometry, internal coolant, and IchAda coating helps you improve workflow by delivering clean, accurate holes on first pass, reducing rework and downtime. You gain predictable tool life in demanding materials, faster cycle times, and reliable performance across batches, making it a smart, dependable choice for micro drilling tasks.
