16-piece Concrete Core Drill Bit Set, Concrete Hole Saw for Dry Core Drilling, 7 Core Bits (30, 40, 50, 65, 80, 100, 110mm) with 100mm and 300mm SDS Plus & SDS Max 6 Centering Drill Bits

【HIGH-QUALITY MATERIAL】: The bell cutter is manufactured using high-frequency welding technology, heat-treated, and hardened with 40CR. Made of hardened metal with excellent hardness and toughness. It is durable and can be used in the harshest conditions, ensuring uncompromising performance.
【SHARP HOLE】: The concrete bell cutters have four cutting edges. Compared to bell cutters with two edges, these are much less abrasive and can pierce hard materials more easily. The dry bell cutter has a precise angle of 135°, making it easier to drill through walls. Seven different sizes (30, 40, 50, 65, 80, 100, 110mm) are included to meet various diameter needs.
【FEATURES OF THE SCIE CLOCHES】: The concrete drill bit is made of a one-piece casing and is equipped with a replaceable centering drill. The body of the scie-cloches is designed with ventilation holes that allow the dust generated during drilling to escape freely, ensuring cleaner and safer work.
【MULTIPLE EXTENSION RODS】: We provide two lengths of SDS centering rods: 100mm and 300mm, and a 300mm SDS-max connecting rod to meet different depth needs. In addition, 3 interchangeable centering drills are included. This set is ideal for drilling materials such as masonry, concrete, natural stone, brick, foam brick, etc.
【MAINTENANCE】: The high-quality coating on the surface of the bell jar prevents rust. In addition, the concrete bell jars have been treated with lubricant at the factory to ensure smooth operation. After use, it is advisable to clean and relubricate the concrete drill bit, bell jar, and other components to reduce wear and extend the life of the tool.

The bell jar set is an indispensable drilling accessory for building workers and maintenance technicians.
