Description
Drillco 91SE224K 1-3/8 Annular Cutter 1 DOC with Pin is a high-performance HSS annular cutter designed for efficient large-diameter holemaking. Engineered to remove only the periphery of the hole, it ejects the slug cleanly while reducing thrust and energy use. Ideal for fabricators, metalworkers, and industrial applications, this cutter ensures smooth finishes, consistent results, and long-lasting performance.
