FISCHER SDS Hammer Drill Bit:SDS Max IV 22/400/520

This FISCHER SDS Hammer Drill Bit features an SDS Max IV shank designed for secure attachment to heavy-duty rotary hammers, ensuring reliable power transmission during demanding tasks. Crafted with a nominal diameter of 22mm, it is engineered to penetrate dense materials efficiently, offering a balance between hole size and drilling speed. The bit provides a working length of 400mm, allowing users to reach deep into concrete or masonry without the obstruction of excessive shank length, while the total length extends to 520mm for overall tool compatibility. Buyers select this specific configuration for professional applications requiring substantial depth and diameter, where standard SDS Plus bits lack the necessary torque and stability. When choosing a replacement or new tool, ensure the shank type matches your hammer’s SDS Max socket and that the working length suits your deepest expected drilling requirements, while the 22mm diameter aligns with your anchor or pipe size needs.
