Hougen® 12,000-Series Stack-Cut Annular Cutters are crafted from hardened M2 High-Speed Steel and feature patented Hougen-Edge® geometry. Engineered for materials up to 275 BHN (28.5 HRC), they combine stack-cut inside-out tooth design with a tapered inner diameter to deliver fast, burr-free multi-plate drilling and effortless slug ejection.

Continuous Multi-Plate Drilling

Unique inside-out tooth geometry cuts smoothly through multiple stacked plates in a single pass without stopping to clear intermediate slugs.

Standard "Top Hat"

Stack-Cut Cylinder

Clean Cylinder Slug Ejection

Produces a round cylinder slug rather than a standard "top hat" slug, protecting cutting edges from binding, chipping, or snapping.
