Husqvarna G-Series Redi Lock Surface Prep Tools
Husqvarna G-Series Redi Lock Surface Prep Tools are metal-bond diamond tools designed for high-production surface preparation and aggressive concrete grinding, with configurations available for different concrete hardnesses and adhesive removal applications. The G-Series uses single or double hexagonal and round segments, depending on the tool; hexagonal segments are generally used earlier in the grinding process for heavier, more aggressive grinding, while round segments are selected for their finer grit sizes and shape to help reduce scratching during finer grinding stages. The tools feature the industry’s largest segments at 0.5″ (13 mm) high, a strong base plate, and a milled Redi Lock tab for secure attachment to carrier discs. All listed tools fit Husqvarna PG 530, PG 680, and PG 820 planetary grinders.
The G 670 uses a hard bond for soft concrete and abrasive surfaces such as broom-finished concrete and ceramic tile adhesive; the supplied product listing is Grit 100/120, while the range information states grit sizes 20 and 30 are available. The G 640 uses a medium bond for medium to hard concrete and is offered in single or double hexagonal or round configurations, while the G 620 uses a soft bond for very hard concrete and is available in single or double hexagonal or round configurations. The supplied G 640 single-segment presentation is Grit 50/60, while the G 640 double-segment presentation is Grit 100/120, and the G 620 single-segment presentation is Grit 100/120.
