Flat MultiDrill MDF Series

Coated carbide drills for spot facing

The flat MultiDrill MDF type is a solid carbide drill that can be used for various purposes including high-efficiency spot facing and drilling in inclined and curved surfaces. It can be used in a variety of drilling applications thanks to its point angle of 180° so that it is applicable to high-efficiency spot facing, drilling in non-horizontal surfaces such as inclined and cylindrical surfaces and interrupted drilling. It also reduces burrs at hole exits by more than half compared to general-purpose drills.


Features
> Effective for inclined and curved surface spot drilling
> Reduced burrs at hole exits
> Applicable for interrupted and cross drilling

MLDH

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 - 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.

Features
•  New "TiAIN" PVD coating
•  Good drill rigidity
•  Optimal thinning and edge balance
•  Excellent wear resistance and fracture resistance
•  Stable chip control
