4 cutter head for reinforced concrete and minimise carbide cracks. Design carbide reduce jamming while drilling. Double flute spiral for excellent dust transportation. The most fundamental difference between SDS Plus and SDS Max lies in terms of size. SDS Plus bits are generally thinner and smaller than SDS Max bits. Here are the numbers: SDS Plus shanks have a diameter of 10 millimeters; SDS Max shanks have a diameter of 18 millimeters. Thinner SDS Plus is generally for lighter duty work--mostly for dr illing smaller holes; SDS Max is for heavier duty work--for drilling larger holes. Product inaccordance with the Germany DIN technology standard.
