Berger technologie GmbH MEGA - POINT blue-line

We have one or two questions for you:

Why do you spend so much money every year on having your drill tools ground externally or on frequently purchasing new carbide (HM/VHM) or HSS twist drills? Why not make a one-time investment in a professional drill grinding machine and have it pay for itself within just a few years? In the long term, you save money, material, tied-up capital, spare your employees’ nerves, and most importantly, gain valuable time that you can use for other tasks!

Drill grinding machines from BERGER are:
precise – fast – user-friendly – cost-effective – value-retaining

They help you increase productivity. These ergonomic and easy-to-use precision drill grinders offer you, among other things, the following advantages:

· Significantly increased tool life due to evenly distributed cutting forces on both cutting edges
· Considerable reduction of feed force thanks to precise, symmetrical point thinning
· Improved diameter accuracy – precise and adjustable point geometries produce bore diameters corresponding exactly to the drill’s nominal diameter
· High positional accuracy – the sharp drill point, thinned right to near the center, prevents the drill from “walking” at first contact, enabling it to cut smoothly and precisely, like a center drill for CNC machines
· Re-grinding, thinning, and checking – all in a single clamping
· Perfect drill point geometry including web thinning in just one minute
· Drastically reduced need for new drill tools, as you can now regrind/resharpen your existing drills up to 40 times or more in-house, regardless of whether they’re HM/VHM or HSS drills
· We manufacture the machine completely in-house and use it daily in our own parts production – so we know what we’re talking about!
· SWISS MADE – quality that will reliably serve you for decades!

The prices for our three different professional drill grinding machines start at EUR/CHF 3,600 to 14,950 (depending on model and configuration).
