Drill bit SDS max, 4-blade / spiral, ø 50 x 570 mm, concrete - 1 pcs, 4932430731

SDS-Max Drill Bits, 4-Cutting Edges

• Large carbide blade with patented edge bevels. Provides lower vibrations and optimised drilling performance when encountering rebar, resulting in longer lifespan.
• Specially developed geometry with optimally symmetrical 4 x 90°, strong carbide blade head. Reduces the risk of jamming when hitting rebar.
• Centring point with a 130° apex angle. Easy drilling with precise positioning ensures optimal guidance during drilling.
• Strong additional blades with a dynamic, curved cutting edge. Supports the main blade for faster drilling.
• Shorter drill spirals. Faster removal of debris from the drill tip to the groove = less wear and reduced temperature at the drill head.
• Innovative, unique carbide blade. Greater amount of tungsten carbide in drills with every diameter ⌀ > 32 mm.
• Visible wear indicator on the main carbide tip. Ensures accurate diameter, e.g., for anchor installation. Lifespan indicator for warranty claims.
• Patented, reinforced spiral geometry. Smooth drilling with low vibrations. Stronger spiral means fewer fractures. Best transfer of impact energy to the blade.
• Deep spiral ensures removal of large amounts of dust for optimal drilling speed, less wear, and reduced temperature increase.
• Drilling with low vibrations. Comfortable drilling providing less strain on the user and the device.
• Special surface treatment. Shot peening creates a smooth surface and densifies its structure, making the drill more resistant to abrasion.
• PGM mark. Guarantees precise holes during anchor installation throughout the drill's lifespan.
