    Drill problem solution with extremely low burr formation

    The ADF is a flat drill or spot-facing tool that is used when a normal drill has reached its limits. In the view of OSG, the product, which will be presented for the first time at EMO Hannover 2017, is the measure of all things at the moment in terms of geometry, flute shape and coating.

    The ADF is deemed a problem solver for inclined or round surfaces and in deep-hole or transverse drilling, where burr formation must be minimized.

    Although the ADF looks like a double-edged milling tool, it is actually a drill with a 180° tip angle that can be used to drill holes on inclined or even round surfaces such as shafts. The manufacturers at OSG, however, also envisage their product being used as a pilot drill in deep-hole drilling. Spot-facing tools like this are apparently not new, yet the ADF is claimed to be cutting-edge in terms of geometry, flute shape and coating. This is mainly thanks to the company's new premium Egi-As coating, which boasts an excellent level of wear resistance. This mainly protects the new and very sharp cutting geometry. Significantly lower cutting forces are required as a result, and this in turn leads to a considerable reduction in the formation of burr, especially where burr has to be avoided as in the case of transverse bores. The tool is currently being used to drill oil supply bores in transmission shafts, the exhibitors report. The very small amount of burr is easily removed by means of an electrical process. The new spot-facing tools are also seen as predestined for use in pre-cast holes or sinks. Although the drill is designed for a range of applications, the super-sharp cutting edges mean that its use is somewhat limited when hard, brittle materials have to be processed. Diameters between 2 and 20 mm are available.
