Drillco annular cutter details
Drillco 1‑7/16 Annular Cutter 3" DOC Nitro (93N228)
Drillco 93N228 1-7/16" Annular Cutter, 3" DOC, Nitro is designed for precise and efficient drilling in structural steel, fabrication, and heavy-duty metalworking. Using the broach cutting method, this cutter removes only the periphery of the hole, reducing thrust and operator effort while ejecting a clean slug for smooth, burr-free holes. The Nitro-enhanced construction delivers excellent durability, faster penetration, and consistent cutting performance. Its double-cut tooth design allows for aggressive material removal, while the optimal flute geometry ensures fast cutting with a fine finish. The brazed shank provides concentricity and reduces vibration during operation.
