SDS+ Hammer Drill Bit 4-Flute 12 x 210 mm

* Ø: 5-14 [mm]

* The Drill Head:

* Our "VF-4" offers 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 hitting reinforcement. The one-piece solid carbide plate is embedded in the steel body with maximum contact surface. This creates a unified bond between head and flute, especially when compensating for impacts and torsional forces. Furthermore, the special head geometry produces perfectly circular boreholes and maintains dowel compatibility with maximum tool life (ideal for direct mounting).

* The Flute:

* The genuine 4-flute helical geometry distributes loads evenly across all flutes. This achieves vibration-free drilling behavior. The four high-volume discharge flutes quickly remove drill dust from the borehole. High-quality special steel makes it extremely bend and fracture-resistant. The special surface treatment additionally increases resistance to wear.

* Application:

* Suitable for concrete and natural stone
