SDS+ Hammer Drill Bit 14 x 210 mm, 4-Flute VF-4

* Ø: 5-14 [mm]

* The Drill Head:

* Our "VF-4" offers an optimally symmetrical head geometry with 4 solid carbide cutting edges. This allows the "VF-4" to run extremely vibration-free and does not jam when striking reinforcement. The one-piece solid carbide plate is embedded in the steel body via a maximum contact surface. The head and flutes form a unit, especially when compensating for impacts and torsional forces. Furthermore, the special head geometry creates perfectly circular bore holes and remains dowel-compatible with maximum service life (ideal for direct installation).

* The Flutes:

* The genuine 4-flute helical geometry distributes the loads evenly across all flutes. This achieves vibration-free drilling behavior. The four large-volume discharge flutes quickly remove the drill dust from the bore hole. High-quality special steel makes it extremely resistant to bending and breakage. The special surface treatment further increases durability.

* Application:

* Suitable for concrete and natural stone
