Description
OSG Micro Carbide Drill, 0.85 mm diameter, is built for precise, deep-hole work. Equipped with 5D internal coolant channels, it efficiently evacuates chips and delivers targeted cooling inside the hole, helping to maintain tight tolerances and extend tool life across a range of materials.
Featuring an IchAda coating for enhanced wear resistance, this micro drill delivers reliable performance in high-speed and demanding machining environments. Its refined carbide geometry ensures accurate hole size and a smooth finish, making it versatile for intricate operations on diverse materials.
- 5D internal coolant channels for efficient chip evacuation: Directs coolant and chips away from the cutting edge to minimize heat buildup and improve hole quality in deep-hole applications.
- IchAda coating for wear resistance: Boosts durability and enables sustained performance at high speeds, reducing tool wear over long production runs.
- Micro carbide with precise geometry: Delivers accurate, clean holes with a smooth finish across a variety of materials, supporting consistent results in micro-machining tasks.
By combining efficient cooling, robust wear protection, and precise micro-geometry, this drill helps you achieve dependable hole quality with less rework, faster cycle times, and longer tool life—enhancing overall productivity in micro-drilling projects.
