Specifications
Product Description
Engineered for Hard Material Drilling: Each bit in this set features a segment of industrial diamond grit bonded to a steel core through a vacuum brazing process. This creates a durable cutting edge designed to grind through abrasive materials like concrete, masonry, natural stone, and porcelain tiles with high efficiency.
Comprehensive Size Range for Versatility: The set provides a practical selection of eight diameters to cover a wide variety of tasks. From small anchor holes (6-12mm) to large core holes for pipes and conduits (35-68mm), this collection is suitable for electricians, plumbers, and general construction work.
Universal M14 Connection System: All bits and the included 65mm adapter shank feature the standardized M14 threaded connection. This system allows for quick and secure attachment to most professional-grade rotary hammer drills, ensuring compatibility and convenience on the job site.
Robust Construction for Professional Use: The core bodies are made from 40Cr or C45 carbon steel for strength, while the diamond segments use 46# or 50# grit for an optimal balance of cutting speed and surface finish. The red painted finish provides easy size identification, making this a reliable and efficient tool set for trade professionals.
