Description
The OSG Micro Carbide Drill — Micro Spiral, Long Reach, SC Coated — is a precision micro-drilling tool designed for small, exact holes in hard‑to‑reach areas. With a 0.74 mm diameter, it excels in electronics, aerospace, and medical components where tight tolerances and clean hole quality are essential.
Its long-reach geometry lets you access deep cavities and blind bores without repositioning the workpiece, while the micro spiral flute provides efficient chip evacuation for smooth, consistent cutting. The SC coating reduces friction and wear, helping the drill stay sharp longer in demanding materials and high-speed applications.
- Long-Reach Geometry: Access deep bores and recessed features without reworking the setup, increasing first-pass accuracy and reducing secondary operations.
- Micro Spiral Flute for Chip Evacuation: Efficient chip removal at micro-diameter scales minimizes clogging, heat buildup, and vibration for cleaner holes and steadier cuts.
- Wear-Resistant SC Coating: Lowers friction and extends tool life in challenging machining environments, delivering reliable performance over more holes between changes.
This drill is engineered to enhance your micro‑drilling workflow by delivering precise holes with fewer adjustments, improved surface finish, and longer tool life across electronics, aerospace, and medical manufacturing applications.
