CAT SDS-Plus hard rock drill bit set 10-piece tungsten carbide DA03901

The CAT DA03901 is a 10-piece SDS-Plus hard masonry drill set for drilling into concrete, stone and brick. Each bit has an SDS-Plus shank, so it fits most modern rotary hammer drills. The set includes bits in 5, 6, 7, 8, 9, 10 and 12 mm diameters, covering a range of hole sizes in one kit.

The centring tip keeps the bit from slipping when you start a hole, and the double-fluted design clears dust quickly from the hole. The tungsten carbide tips resist wear and heat, allowing extended use in hard materials. The bit bodies are made of hardened chrome vanadium steel, which provides good resistance to breakage. The set is stored in a sturdy box with a SLIDELOCK clasp.

This set suits professionals and DIY users who need dependable bits for demanding drilling work in hard materials.
