Particularly durable and robust for drilling in reinforced concrete – this user need is met by the new SDS max-8X hammer drill bit from Bosch. The SDS max-8X is the only four-cutter hammer drill bit with full tungsten carbide head on the market offering a diameter of up to 28 millimeters – common models of-fer maximum 16 millimeters. This is made possible by the unique Bosch diffu-sion welding technology (IDS). This ensures an extremely strong and durable bond between the carbide head and the steel spiral, which is exceptionally re-sistant to changes in temperature: Unlike common drill bits, the Bosch SDS-plus-8X hammer drill bit remains unaffected by high temperatures of more than 400 degrees which can potentially occur when drilling in reinforced concrete. The advantage is a long lifetime: The SDS max-8X offers a lifetime that is 50 percent longer than its predecessor SDS max-7, which already had a longer lifetime than equivalent competitor models. Drilling into reinforced concrete, set-ting rebars or guiding pipes through walls: The range covers all common appli-cations in the SDS max segment with diameters from 12 to 28 millimeters.

High drilling efficiency thanks to special carbide head design

An additional advantage of the SDS max-8X drill is the special design of the four-cutter full tungsten carbide head: In contrast to common hammer drills, it does not have inclined cutting edges but, instead, comes with flat 180-degree cutting edges. This geometry allows for maximum transfer of impact energy, which in turn translates into higher drilling efficiency. SDS-max-8X drills also have an extremely sharp, pyramid-shaped centering tip, which provides accu-racy.

The SDS max-8X hammer drill bit is available now. All prices are recommended retail prices excluding VAT.
