2.Craft & Performance
All grinding heads inside the Hex Shank Drill & Grind Integrated Bit Set with Chamfer Tool adopt high-temperature vacuum brazing exposed diamond sand craft, which firmly locks high-hardness industrial diamond grit on the metal substrate. The uniform exposed abrasive grain structure of the Hex Shank Drill & Grind Integrated Bit Set with Chamfer Tool greatly improves chip removal efficiency during dry grinding, effectively avoiding powder clogging and high-temperature burn on stone slab surfaces. The thickened anti-break hexagonal shank of the Hex Shank Drill & Grind Integrated Bit Set with Chamfer Tool maintains stable clamping inside hand drill chucks, no slipping or shaking during high-speed rotation. Four sizes of straight cylindrical grinding bits in the Hex Shank Drill & Grind Integrated Bit Set with Chamfer Tool handle narrow hole inner wall polishing, residual burr removal and tiny hole expanding work. The matched conical chamfer tool of the Hex Shank Drill & Grind Integrated Bit Set with Chamfer Tool quickly creates smooth 45-degree arc chamfers on tile hole edges without chipping or scratching material surfaces. No water cooling is required during operation of the Hex Shank Drill & Grind Integrated Bit Set with Chamfer Tool, which keeps construction sites clean and improves continuous processing efficiency for workers every time you use the Hex Shank Drill & Grind Integrated Bit Set with Chamfer Tool.
Application
The multi-functional integrated design of the kit covers all fine processing procedures of hard brittle building materials. The straight grinders can grind and expand small holes on vitrified tile, rock slab, marble, granite, quartz stone and artificial stone countertops, remove sharp inner hole burrs and polish uneven hole walls.
The conical chamfer bit equipped in the kit is specially used for edge chamfering of drilled holes to form smooth rounded transitions, preventing hands from being scratched by sharp tile edges. This product is widely applied in bathroom hardware installation, cabinet countertop modification, wall tile repair, stone handicraft polishing and household DIY stone processing projects. Since the whole kit supports fully dry grinding without water, it is convenient for temporary indoor renovation and outdoor maintenance operations with portable electric hand drills.
