Hermesmeyer & Greweling GmbH & Co. KG relies on Nine9 Cutting Tools. Hermesmeyer & Greweling GmbH & Co. KG ( H&G) is a well-known contract manufacturer for tool making as well as machine building.
The use of the 142° Nine9 NC Spot Drill gives H&G the chance to dispense the pilot boring very often. H&G do not have to do the pre-drilling anymore.
H&G can abstain from reduced feed rate when they have adverse conditions on the surface. A high speed centering tool shows a lot less abrasion than usually. The tool life of the high performance drill increase cause of the reduced vibration during the first cut.
It saves about 20 minutes in changing times and cutting times. H&G is very satisfied with the use of Nine9 99619-V142 NC Spot Drill and would like to take further actions to implement other tools of the Nine9 portfolio into the company.
