Custom Large Diameter Extrusion Taps

Custom Large Diameter Extrusion Taps are precision-engineered forming tools designed for high-performance internal threading in heavy-duty machining environments. Unlike traditional cutting taps, these taps form threads through cold metal displacement—producing stronger, cleaner, and more dimensionally consistent threads with zero chips.

Premium HSS-E / Cobalt Construction

High-speed steel with cobalt alloy ensures exceptional hot hardness, wear resistance, and toughness for long service life under heavy loads.
Chip-Free Forming Technology
No swarf, no clogging, and no risk of chip jamming in deep or blind holes—eliminating common causes of tap breakage and thread damage.
Custom Large Diameter Sizes
Made to your exact specifications, including non-standard large diameters, special pitches, and modified geometries for blind/deep holes.
Superior Thread Strength & Finish
Cold forming preserves the material’s grain flow, resulting in threads with up to 30% higher tensile strength and a smoother surface finish.
Wide Material Compatibility
Works reliably with ductile materials including aluminum alloys, die-cast aluminum, mild steel, alloy steel, copper, and brass.
Surface Coating Options
Available with TiN, TiCN, TiAlN, or custom coatings to enhance wear resistance, reduce friction, and extend tool life.
