MicroDrills/DLC Coated Drills Micro Long Drills ivmuiv i-vny UIIIIO MLDH-L / MLDH-P Type General Features Micro Long Drills are oil-hole drills for high efficiency drilling that were developed for drilling deep, small-diameter holes. These next-generation, small-diameter hole drills feature improved strength - often a problem area with small-diameter drills. Deep-hole drilling New groove shape ensures good drill rigidity and chip evacuation. High efficiency drilling to depths of over 20x drill diameter at over Vf=500mm/min (drill diameter 1.3mm, SUS416 equivalent). Optimal thinning and edge balance for stable chip control. Long tool life Special coating provides long tool life with a wide variety of work materials. Improved chip evacuation makes it possible to reduce spindle load fluctuation, ensuring stable tool life.
