Milwaukee SDS+ MX4 concrete drill bit set 5 pcs 4932352833

Large carbide tip with a patented bevel. It ensures low vibration and optimal drilling performance even during prolonged use on reinforced concrete. Specially developed robust head geometry with optimal symmetry of the 4 x 90° carbide tip. Prevents jamming when striking reinforced concrete. Centering point with a 130° angle. It ensures easy, high-precision spot drilling and optimal guidance during drilling. Large secondary cutting edge with a dynamically curved cutting edge. It supports the main blade and ensures faster drilling. Shorter spiral flutes. Faster removal of drill dust from the head to the flute = less wear and heat build-up at the tip. Innovative, unique carbide tip. More carbide across the entire diameter and even beyond the diameter for ø> 32 mm. Wear mark on both main cutting edges. It ensures diameter accuracy, e.g., for anchoring. Lifetime indicator for warranty claims. Patented reinforcement of the drill bit geometry. Lower vibrations for better drilling. The reinforced flute minimizes drill breakage. Improved energy transfer to the tip. Deep flute shoulders. Removal of large amounts of drilled dust for optimal drilling, less wear, and less heat buildup at the tip. Low vibration during drilling. Comfortable drilling ensures less mechanical stress on the tool and less strain on the user. Specially treated surface. Abrasive treatment ensures a smooth surface and densification of the surface structure, making the drill bit more wear-resistant. PGM marking. Ensures precise drilling of mounting holes throughout the drill bit's service life.
