    MLDH Micro Drills


    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.

    Characteristics and Applications
    – 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.
