SDS+ Hammer Drill Bit VF-4, 12 x 160 mm, 4-Flute

* 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 smoothly with minimal vibration and prevents jamming when striking reinforcement. The single-piece solid carbide plate is embedded in the steel body over a maximum contact surface. Thus, the head and spiral form a unified structure, especially when it comes to compensating for impacts and torsional forces. Furthermore, the special head geometry produces perfectly circular drill holes and remains wall plug compatible with maximum tool life (ideal for direct fastening).

* The Spiral:

* The genuine 4-flute helical geometry distributes the load evenly across all spirals. This achieves smooth drilling behavior with minimal vibration. The four large-volume chip evacuation flutes quickly remove drill dust from the borehole. High-quality special steel makes it extremely resistant to bending and breaking. The special surface treatment further increases durability.

* Application:

* Suitable for concrete and natural stone
