Solid carbide micro long drills
MLDH 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 which is often a problem area with small-diameter drills. Special PVD coating provides long tool life with a wide variety of work materials.
High efficiency drilling to depths of over 20x drill diameter at over Vf= 500mm/min
Hole depth (L/D): 2D / 5D / 12D / 20D / 30D
Excellent wear and fracture resistance
Optimal thinning and edge balance for stable chip control
Special groove shape ensures good drill rigidity
Reduced spindle load fluctuation
Stable long tool life
