DEWALT DT4585-QZ punta Forstner 85 mm attacco esagonale 10 mm acciaio al carbonio

An 85 mm cutting diameter and precision-ground edges make this DEWALT Forstner bit the go-to for large-diameter, flat-bottomed holes in wood, chipboard, MDF, and plywood. The hex shank locks into 10 mm chucks of corded drills, cordless drills, and drill presses, while the optimized flute design clears chips fast to keep the cut clean and cool.
