OSG Micro Carbide Drill - Micro Spiral - TiAlN Coated - 0.22mm

OSG Micro Carbide Drill – 0.22 mm diameter with a micro spiral flute and TiAlN coating – is a precision drilling tool crafted for micro-scale holes in electronics, medical devices, and other fine applications. Its compact size and exacting geometry help you achieve tight tolerances without compromising edge quality.

Engineered for reliability, this micro drill delivers accurate hole size and smooth drilling performance even at higher speeds, while the TiAlN coating enhances wear and heat resistance to extend tool life in hard or abrasive materials. The result is consistent results you can depend on for repeated manufacturing or detailed prototyping.

• Micro Spiral Flute for Efficient Chip Evacuation: The micro-scale flute design channels chips away from the cutting edge, reducing clogging, heat buildup, and rubbing. This supports clean entry and exit and helps maintain hole quality in delicate workpieces.
• TiAlN Coating for Wear and Heat Resistance: A robust coating that protects the cutting edge from wear and high temperatures, enabling reliable performance at higher speeds and in hard or abrasive materials, so you can push productivity without premature tool failure.
• Premium Micro Carbide Construction for Precision: A stiff carbide core delivers consistent hole diameters with minimal deflection, ensuring repeatable results across electronics, medical device components, and other high-precision micro-machining tasks.

With this drill, you gain a dependable micro-drilling solution that supports faster setups, fewer tool changes, and tighter tolerances — helping you finish projects on time and to spec, whether you're prototyping, manufacturing, or repairing small-scale assemblies.
