MLDH - Micro Long Drills for small-diameter holes
October 21st 2015| 68 Calls
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 - often a problem area with small-diameter drills.
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, X12CrS13 equivalent). Optimal thinning and edge balance for stable chip control. 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.
