High performance carbide flat drills that combine two operations designed for various applications.

OSG’s Exocarb ADF drills combines two operations in one for the drilling of inclined surfaces and counter boring applications.

The ADF was developed with an “all-purpose” concept for versatility, reliability and quality for flat-bottom holes. 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 minimises the shifting of hole position. Its sharp cutting edge results in low cutting force to minimise 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 new proprietary EgiAs coating, tool life can be prolonged with excellent heat and wear resistance.

The ADF is engineered for a wide variety of drilling applications including inclined surfaces, curved surfaces, counter boring, eccentric holes and thin plates. It is suitable for common materials such as carbon steel, alloy steel, hardened steel (up to 35 HRC) and cast iron. Standard types are available in diameters from 2 to 20mm and long types are available in diameters from 3 to 20mm.
