Hougen® Xtreme Cobalt™ Annular Cutters

Hougen® Xtreme Cobalt™ Annular Cutters are engineered for extreme conditions, demanding materials, and users who want maximum tool life without compromise. Built from premium M42 cobalt steel and finished with Hougen’s advanced IronEdge™ coating, these cutters are designed to outperform standard HSS and coated annular cutters in abrasive, high-heat, and hard-to-machine applications.

The exclusive Hougen tooth geometry promotes smooth chip evacuation, reduced vibration, and consistent hole quality, even in challenging materials. IronEdge™ coating further reduces friction and heat buildup, allowing the cutter to run cooler and last longer under continuous use.

Xtreme Cobalt™ annular cutters are ideal for structural steel, alloy steel, stainless steel, and other tough materials commonly encountered in fabrication, maintenance, and industrial environments. Each cutter is precision-ground for accuracy and is designed for use with magnetic drills, making them a dependable choice for professionals who demand reliability and repeatable performance.

All Xtreme Cobalt™ annular cutters include a pilot pin, ensuring proper alignment, improved cutting efficiency, and easy slug ejection.
