SDS+ Hammer Drill Bit 4-Edge VF-4, 10 x 210 mm

* 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 low-vibration and does not catch when striking reinforcement. The one-piece solid carbide plate is embedded in the steel body via maximum bonding surface. This creates a unit from head and flutes, especially when it comes to compensating for impacts and torsional forces. Furthermore, the special head geometry produces perfectly circular drill holes and remains anchor-compatible with maximum tool life (ideal for direct installation).

* The flutes:

* The genuine 4-flute spiral geometry distributes loads evenly across all flutes. This achieves low-vibration drilling behavior. The four large-capacity conveyor flutes quickly remove drill dust from the bore hole. High-quality special steel makes it extremely resistant to bending and breaking. The special surface treatment additionally increases resistance.

* Application:

* suitable for concrete and natural stone
