Super MultiDrill XHGS Series

High efficiency solid carbide drills for deep hole drilling

The XHGS Type is a next-generation drill for deep hole drilling, features stable chip control and improved strength to further enhance efficiency of deep hole drilling. The application of a new special thinning shape "RX thinning" reduces cutting resistance during high efficiency drilling. New groove shape "J flute" with improved chip control stability when drilling deep holes. Improved chip evacuation makes it possible to reduce spindle load fluctuation, ensuring stable, long tool life. The XHGS Type provides excellent guide performance due to the unique design when compared to the conventional drill.

> Higher efficiency in deep hole drilling: 12D, 15D, 20D, 25D, 30D
> Low cutting resistance by special "RX thinning" shape
> Improved chip control by new groove shape "J flute"
> DEX coating provides long tool life
> Compatible with MQL system

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.

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

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.

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