Condition: new, Year of construction: 2026, operating hours: 1 h, functionality: fully functional, BERGER drill grinding machines are precise - fast - simple - economical And they help you increase productivity. These ergonomic and easy-to-use, precise drill grinding machines offer you, among other things, the following advantages: • Significantly increased tool life of your drills through even distribution of cutting forces across both cutting edges • Significant reduction of feed forces thanks to precise, symmetrical point thinning • Improved diameter accuracy - the precise and optimizable grinding results in holes whose diameter exactly matches the nominal diameter of the drill. • Improved positional accuracy - the sharp drill tip, precisely pointed and close to the center, no longer "wanders" upon initial contact with the workpiece, but cuts smoothly from the start • Resharpening, point thinning, and inspection in a single setup Furthermore, the purchase of new drilling tools is drastically reduced, as you can now resharpen your existing drills up to 40 times or more in-house! So you're not only protecting the environment, but also your wallet, and, most importantly, your employees' nerves! Keep up with the times... keep up with BERGER technology.
