HTG-680 GBD Dual Drive – 3 Phase Grinder – 12.8 KW

HTG-680 GBD Gear Bi-Directional Floor Grinder – Advanced Floor Grinding Technology for Superior Concrete Finishing

The HTG-680 GBD is a high-performance, gear-driven floor grinder designed for professionals who demand precision, efficiency, and versatility in concrete surface preparation and polished concrete finishing. Engineered by High Tech Grinding (HTG), this model introduces the revolutionary GBD (Gear Bi-Directional) Technology—a game-changing innovation that sets new standards in the floor grinding industry.

What is GBD Technology?

GBD (Gear Bi-Directional) enables two core functionalities never before seen in conventional grinding machines:

• Adjustable Gear Ratios between the plate and gearbox—giving operators full control over machine performance based on surface hardness and finish goals.

• Directional Switching of the plate and gearbox—choose between synchronised or counter-rotational movement to optimise surface flatness, grinding depth, and job efficiency.

This intelligent system enhances the grinding process, making the HTG-680 GBD perfect for medium to large concrete grinding and polishing jobs.
