OSG Corp.'s ADO-Micro small diameter coolant-through drill series are designed for stable, high efficiency drilling in small diameter deep hole applications.

 Poor chip evacuation is a common complication in small diameter deep-hole drilling. Micro sludges can be easily accumulated around the outer periphery of the cutting tool, which is a key cause of abrupt tool breakage. The ADO-Micro features a unique double margin geometry with an extended flute and shortened end margin to enhance chip evacuation capability. In addition to the outstanding chip ejection performance, the double margin configuration supports the straightness stability of the tool and reduces rifle marks on the inner surface of holes.

Furthermore, the drill features a pair of large oil holes and employs a hollow shank design to allow large coolant flow volume for trouble-free chip evacuation. The ADO-Micro is coated with OSG’s original IchAda coating that provides excellent surface smoothness in conjunction with high abrasion resistance and heat resistance to enable small diameter tools to achieve long tool life.

With the drill's unique tool geometry and IchAda coating, non-step drilling is made possible even for deep-hole applications, enabling high processing efficiency.

The ADO-Micro is suitable for carbon steel, alloy steel, stainless steel, cast iron, ductile cast iron, aluminum alloy, titanium alloy and heat resistant allo and is available from diameters 0.7 mm up to 2 mm for drill lengths 2xD and 5xD, and diameters 1 mm to 2 mm for drill lengths 12xD, 20xD and 30xD.
