OSG Micro Carbide Drill - Micro Spiral - TiAlN Coated - 1.66mm CMTHOLDER With HSS-E substrate and aOSG Micro Carbide Drills with a micro spiral flute are precision tools designed for ultra fine drilling tasks. They excel in electronics, medical devices, and other detailed applications where holes must be exact and repeatable. The combination of carbide hardness and a refined flute geometry helps ensure clean starts and precise hole sizes even in challenging materials. Coated with TiAlN, these drills resist wear and heat, enabling higher cutting
