The Alfra 1902018025 core drill made of HSS-Co Rqx is a highly advanced tool specifically designed for precise drilling in metal. With a diameter of 18 mm and a robust RQX coating, this core drill offers excellent performance and durability. The Weldon shank with a diameter of 19 mm ensures a secure connection with the drill machine, while the internal bore of 6.35 mm allows for efficient chip removal. The core drill only removes a thin ring of material, minimizing material stress and reducing the risk of breakage. Thanks to the innovative design, the stuck drill core is ejected by spring force through guide and ejector pins, making handling easier. This core drill is ideal for applications where high precision and efficiency are required.

• RQX coating for increased durability
• Efficient chip removal to minimize the risk of breakage
• Spring force mechanism for ejecting the drill core
• Pre- and post-cutters for improved cutting performance.
