Features
Feature Listing for Dry Drill Drill Head (3000063697)
Precision-engineered diamond drill head for ultra-fast concrete perforation, featuring industrial-grade diamond grit for unmatched durability. Patented air-cooled wall design prevents overheating, ensuring continuous operation at 1500-3000 RPM without performance drop. Specialized pore opening geometry creates clean 5-40mm diameter holes in reinforced concrete/brick with zero chipping. Electroplated segment bonding technology extends lifespan to 3X conventional bits when drilling granite/marble. Professional-grade tungsten steel core withstands 800°C for demolition work, HVAC installs, and electrical conduit projects. Optimized flute design expels debris 40% faster than standard bits - ideal for overhead and vertical surface drilling. Certified for use with rotary hammer drills (SDS-Plus/SDS-Max) in construction, plumbing and industrial maintenance. Micro-groove cooling channels maintain bit integrity during prolonged dry drilling operations.
