Among the highlights on the stand of tooling expert Mapal at the EMO exhibition in Hanover last month were the deep drills of the company’s new MEGA-Deep-Drill-Steel product range. Designed for machining steel and cast iron, users can achieve depths up to 40xD.

The solid-carbide deep drills feature protection via a coating with HiPIMS technology in the cutting edge area, ensuring frictionless chip removal. The remaining length of the MEGA-Deep-Drill-Steel remains uncoated. Thanks to its geometry, Mapal says the new deep drills stand for long tool life and high productivity. Compared with its previous-generation tools, it is possible to can attain up to 50% higher feed rates.

Mapal also presented a series of new cylindrical shank reamers with brazed cutting edges. A special feature of the FixReam 700 reamers is their high usability, derived from an expansion system. It is possible to re-grind a tool twice before new cutting edges require brazing-in. After that, the tool can benefit from two more re-grinds before replacing the cutting edges again and performing yet two further re-grinds. Tool costs reduce by up to 15% in comparison with a tool that does not have an expansion function. Furthermore, thanks to new (patented) geometries, users achieve up to 30% better roundness and cylindrical form, as well as improved chip removal, compared with other cylindrical shank reamers.

Also taking the spotlight at EMO was Mapal’s new OptiMill-Alu-Wave for aerospace customers, a tool that can deliver material removal rates of up to 21 litres per minute when machining aluminium.
