Product Details The Nils USA Auger Replacement Slick Cutting Head keeps holes coming fast when late-season ice turns wet, heavy, and unforgiving during walleye, perch, crappie, or panfish missions. Built for Nils USA Cordless Drill Augers, this slick cutting head uses a one-piece design that creates a stronger, continuous cutting surface and spins quickly through slush-soaked ice. High chromium steel holds a sharp edge longer than standard auger blades, while curved cutting edges bite immediately and pull themselves through thick ice with minimal downward pressure. When mobility matters and ice conditions change by the hole, this cutting head keeps drilling speed high and fatigue low.
