Hammer drill bit Max Quadro-L

No hooking in and running off centre

The symmetrical 4 x 90° cutting edge geometry prevents the hooking in or running off centre of the drill bit when striking reinforcement or hard pebbles in concrete.

Perfect drilling properties

Thanks to head geometry that is tailored to the drill bit diameter.

• 12–15 mm: Carbide element in one piece (Fig. 1) for high stability thanks to the maximised attachment surface with the steel body.


• 16–30 mm: Multi-piece carbide element (Fig. 2) for faster drilling progress, and trisection design to improve buffering of torsional forces


• 32–40 mm: Extremely wide carbide element in several pieces (Fig. 3) with specially reinforced ends for improved durability when used on high-performance hammer drills.

Optimum guidance in drilled hole

Thanks to the four cutting edges and four-spiral geometry of the drill bit, it is optimally guided into the drilled hole. You get perfectly cylindrical drilled holes, which are optimum for use with anchors.

Constant drilling speed

The drilling speed remains constant throughout the entire service life of the drill bit thanks to the special head geometry.

Precise drilling

The special self-centring tip enables precise tapping.
