Description

This 2.55mm OSG micro carbide drill is designed for precision work in deep or confined spaces where standard tools cannot reach. The long-reach format paired with a micro spiral flute gives machinists a reliable way to create clean holes in tight-tolerance components used across electronics, aerospace, and medical manufacturing.

  • Long-reach shank: Extends access into deep cavities without sacrificing stability, allowing consistent hole placement in parts that would otherwise require multiple setups.
  • Micro spiral flute design: Clears chips efficiently during operation, reducing the chance of clogging and supporting uninterrupted drilling in small-diameter holes.
  • SC coating: Adds a layer of wear protection that lowers friction against the workpiece, helping the drill maintain sharpness over longer production runs.

By combining reach, chip control, and coating protection in one tool, this drill helps users complete precision micro-holes with fewer interruptions and less frequent replacements, keeping projects on schedule in high-spec environments.
