Description

Drillco 91N244 1‑11/16″ Annular Cutter – 1″ Depth of Cut, Nitro is engineered for high-efficiency broach cutting of large diameter holes in tough materials. Its Nitro-treated cobalt construction delivers superior hardness, faster penetration, and reduced thrust, ensuring precise and reliable performance. The cutter removes only the periphery of the hole, ejecting the slug cleanly after drilling, making it ideal for professional and industrial applications requiring speed and accuracy.

Features:

Nitro-treated cobalt for enhanced wear resistance and long-lasting durability
1″ depth of cut (DOC) suitable for medium-to-large holes
Ball nose for profiling, grooving with radii, and contouring
Four flutes for improved surface finish and reduced chatter
Bright finish for smooth cutting and enhanced lubricity
Round shank with 1 flat for secure attachment
Made in USA

Benefits:

Efficiently produces large diameter holes with less energy and effort
Minimizes material waste by removing only the periphery of the hole
Ensures precision for profiling, contouring, and repeatable cuts
Durable and long-lasting for repeated industrial use
