Description

Drillco 91SE448 3-3/4 Annular Cutter 1″ DOC with 1-1/4″ Shank is a high-performance HSS annular cutter designed for efficient large-diameter holemaking. Its broach cutting design removes only the periphery of the hole, ejecting the slug cleanly while reducing energy consumption and cutting thrust. Ideal for professional metal fabrication and industrial applications, it delivers precision, speed, and durability.

Features:

3-3/4″ diameter with 1″ depth of cut (DOC)
1-1/4″ shank for secure and stable attachment
Tip made from solid carbide for maximum hardness and longevity
Carbide base material drills up to 2x faster than standard HSS
118° conventional point for accurate and rapid penetration
Bright finish for enhanced lubricity
Efficiently removes only the periphery of the hole and ejects the slug
Made in USA
