OthersBrazedReamersIndexableIndexableInsert TypeHead TypeSolidDrilling Micro Long Drills 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 drills for small diameter deep holes feature improved strength - often a problem area with small drills. J ■ Features and Applications ●Deep hole drilling New groove shape ensures good drill rigidity and chip evacuation. High-efficiency drilling to depths of over 20 times the drill diameter at over vf=500mm/min (drill diameter ø1.3, equivalent to SUS416). 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 long, stable tool life. ■ Product Range Applications Cat.
