Drillco 3‑7/16 Annular Cutter 4″ DOC 1‑1/4″ Shank (94SE428)

Description

Drillco 94SE428 3-7/16 Annular Cutter 4″ DOC 1-1/4″ Shank is designed for efficient large-diameter hole cutting with reduced thrust and energy requirements. Using broach cutting technology, this annular cutter removes only the periphery of the hole and ejects a clean slug at the end, ensuring faster penetration, smooth operation, and precise results. Built for professional metalworking and fabrication, it combines strength, durability, and accuracy for demanding applications.

Features:

• 3-7/16″ diameter with 4″ depth of cut (DOC)
• 1-1/4″ round shank for secure attachment
• Solid carbide construction for maximum rigidity and strength
• Drills up to 2x faster than HSS cutters
• Self-centering 140° split-point reduces thrust and prevents walking
• Straight flutes increase edge strength and deliver consistent hole sizing
• Bright finish enhances lubricity and cutting efficiency

Benefits:

• Produces large-diameter holes quickly with minimal effort
• Reduces thrust and improves drilling accuracy
• Carbide design ensures long-lasting durability
• Delivers clean, precise holes with smooth surface finishes
• Reliable performance in heavy-duty metalworking applications
