Concrete drill bit with 350 mm round shank, SDS Plus core bit for concrete sawing holes, drill bit for cement stone walls with 30/40/50 mm expansion (Silver)

• Professional Drill Bit Set: This complete drilling kit contains three high-performance drill bits (30 mm, 40 mm, and 50 mm diameters) with matching SDS Plus chucks, precision tungsten carbide guide bits, and a robust 350 mm extension. This set is specially designed for creating clean, precise holes in a variety of masonry applications.
• Versatile Masonry Applications: Ideal for drilling through brick walls (solid and hollow), concrete blocks, red bricks, aerated concrete, and lightweight masonry structures. Perfect for installing air conditioning pipes, ventilation systems, washing machine drain pipes, and other domestic or building penetrations.
• Important Operating Instructions: Designed exclusively for masonry materials; never use on steel, tile, natural stone, or reinforced concrete. Carbide tips require adequate cooling.

Always use water when drilling to prevent overheating and premature wear. Advanced Cutting Technology: Featuring brazed tungsten carbide teeth with reinforced welded joints for maximum durability. The segmented blade design, with its alternating teeth, evenly distributes cutting forces, reducing vibration and preventing edge chipping during operation. Precision Drilling System: The included pilot drill ensures precise hole positioning, while the SDS Plus extension allows for deep wall penetration up to 350 mm. Special anti-vibration grooves minimize drill movement for cleaner holes in brittle masonry materials. src="https://cdn.manomano.com/external-resources/AAHKMJXYDAFdJAOAIMEbOAchMsjc3QZBtjSFHA9dqEpXPSB65XDJrhSVyThNg87jDURivsIQioVkU4HdlEVCOvmJqupLSMDI fZUAQ_v3XTYZwxYwvLYpRNbL-B2xWc_WZQ_hJ6vRmqFJ5Ws6R5UhYuRg8pWFVC3NIB6KAgIw 3TybCiggh3lW6tFhTobwluFAY6glbPk6VW4HjOLeHEwmChINcUVPXAeLydqSlP3saeklBQ==" data-orig-src="https://cdn.manomano.com/external-resources/AAHKMJXYDAFdJAOAIMEbOAchlkWZ0oakZn_uVZ0mPidMNbILvCvspZ4oG3fPgIqc1P3iZBYT4ijBU2OZics_MLIJnZDfQGlQLYpGO_leg46-3w==" />
