Wurth Hammer Drill Bit Max Quadro-L - DRL-HAM-MAX-LL-D16-L340-WL200MM Ref. 0647001634

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: Carbide element in several pieces (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.
