The Husqvarna VARI‑DRILL D20 300 mm is designed for large-diameter, heavy-duty drilling in demanding environments. Suitable for wet drilling with occasional dry use, this bit is ideal for professional tasks like plumbing, ventilation, and utility core penetrations.
Laser-welded diamond segments affixed to a thick steel barrel resist segment loss under high-stress drilling. The universal 11/4″ UNC female connection ensures secure attachment and low-vibration performance in industrial core drills.
