New Coolant-Through Style Added to ADF Flat Drill Series for Stainless Steel Applications

TOYOKAWA―January 1, 2019―OSG Corporation today announced the expansion of its ADF multi-purpose flat drill series for inclined surfaces and counterboring applications with the coolant-through ADFO in 160 sizes compatible for stainless steel.

Machining a flat hole traditionally required the use of an end mill and a drill. The ADF enables one-step drilling, thereby simplifying machining time and tool management. The drill’s balanced point form improves precision and minimizes the shifting of the hole position. Its sharp cutting edge results in low cutting force to minimize burrs even in thin plates. With a wide chip room geometry, trouble-free chip evacuation can be achieved. Furthermore, with the addition of OSG’s proprietary EgiAs coating, tool life can be prolonged with excellent heat and wear resistance.

The ADF series is engineered for a wide variety of drilling applications including inclined surfaces, curved surfaces, counterboring, eccentric holes, thin plates, etc. It is suitable for materials such as carbon steel, alloy steel, hardened steel, cast iron and stainless steel.
