Fein HSS-Nova 50 kernboor 16 mm Weldon 19 mm 63133159052

Drilling large-diameter holes in steel and stainless steel with a twist drill is slow, imprecise, and hard on your tools. The Fein HSS-Nova 50 annular cutter solves this by cutting only the perimeter of the hole, leaving a solid slug and dramatically reducing cutting time and power consumption. With a 16 mm cutting diameter and 50 mm cutting depth, this cutter is ideal for creating clean, burr-free holes in plates, beams, and pipes up to 50 mm thick.
