Drillco 3‑7/8 Annular Cutter 1" DOC 1‑1/4" Shank (91SE456)
Drillco 91SE456 3‑7/8 Annular Cutter – 1" Depth of Cut, 1‑1/4" Shank is designed for high-efficiency broach cutting, enabling you to create large-diameter holes quickly and with minimal energy. By removing only the periphery of the hole, it reduces thrust while cleanly ejecting the slug after the cut. Built for demanding industrial applications, this cutter combines precision, durability, and smooth operation in tougher materials.
3‑7/8" diameter with 1" depth of cut for large-hole fabrication
1‑1/4" round shank for secure attachment and stable operation
