Description
Drillco 91N220 1‑5/16 Annular Cutter 1″ DOC Nitro is a professional-grade broach cutting tool engineered for efficient, precise large-diameter holemaking. Nitro-treated for superior hardness and wear resistance, this cutter removes only the periphery of the hole while ejecting the slug cleanly at the end of the cut. Ideal for metalworkers, fabricators, and industrial applications requiring low-thrust, energy-efficient drilling.
