Drillco 91SE256 1-7/8 Annular Cutter 1 DOC is a high-performance HSS annular cutter designed for efficient large-diameter holemaking. It removes only the periphery of the hole, ejecting the slug cleanly while minimizing energy use and thrust. Perfect for fabricators, metalworkers, and industrial applications, this cutter provides precise results, smooth finishes, and extended durability.
Features:
- 1-7/8″ diameter with 1″ depth of cut
- Premium grade cobalt for milling harder materials
- Center cutting tip for plunging, pocketing, and holemaking
- Multiple flutes (4 or 6) for improved surface finish and reduced chatter
- Bright finish for enhanced lubricity
- Extra long cutting length for additional reach and deeper cuts
- Round shank with 1 flat for secure attachment
- Made in USA
