Heleta's SDS carbide bits feature either the SDS-Max or SDS-Plus drive system for fast bit changes and efficient power transfer from the hammer drill to the bit. All our SDS bits feature the highest quality carbide and provide two extra carbide nibs resulting in four cutting edges. These four cutting edges increase the drilling speed by pulverizing more concrete, also providing a rounder hole than two cutter bits. The flutes provide a fast deep means of clearing concrete dust from deep holes speeding up drill rates.
