Description

The OSG Micro Carbide Drill is a precision tool engineered for micro-drilling tasks that demand exact holes and repeatable results. With a 1.46 mm diameter and a TiAlN-coated micro spiral flute, it delivers dependable performance for electronics manufacturing, medical device components, and other fine applications.

The TiAlN coating boosts wear resistance and heat tolerance, enabling higher cutting speeds and longer tool life, even when machining hard or abrasive materials. The micro spiral flute design enhances chip evacuation and delivers smooth drilling action, helping maintain hole quality and reducing heat buildup during extended cycles.

  • Micro Spiral Flute for Efficient Chip Evacuation: The compact flute geometry clears chips quickly, minimizing clogging, reducing heat, and supporting consistent hole quality in tight-tolerance work.
  • TiAlN Coating for Extended Wear and Heat Resistance: The coating shields the carbide against wear and high temperatures, allowing faster speeds and longer service between sharpening or replacements.
  • Precision Micro-Drilling for Delicate Materials: Engineered to deliver tight tolerances and clean finishes in electronics, medical devices, and other fine parts without compromising accuracy.

In practice, this drill helps you improve workflow by delivering reliable, repeatable holes with minimal tool changes. Its robust carbide composition and protective TiAlN coating make it a dependable choice for demanding micro-structural work, delivering consistent results from prototype to production runs.
