Preminium Quality HSS Cobalt Machine Taps
Premium HSS cobalt machine taps with M2-M30 sizes.
High hardness, anti-breakage, ideal for stainless steel, alloy steel & automotive threading.
Factory direct supply.
Premium HSS Cobalt Machine Taps are professional threading tools built for heavy-duty industrial tapping,
widely searched by machinists, mold factories and metal processing workshops.
Made of M35 high-speed steel with 5% cobalt added, these machine taps solve the common overheating and rapid wear issues of standard HSS taps,
becoming the top pick for hard metal threading tasks.
Our HSS cobalt machine taps carry obvious competitive advantages.
Extra cobalt composition greatly lifts red hardness, so taps stay sharp under high-speed continuous tapping without softening.
Excellent metal toughness avoids tap breakage in blind holes and deep holes.
Spiral flute versions discharge chips fast, reducing scratch on thread surfaces.
All taps undergo precise grinding and uniform heat treatment, delivering consistent thread accuracy and longer service life.
They can be reground multiple times to cut workshop operating costs.
These premium HSS cobalt machine taps fit CNC tapping machines, bench drills and lathes.
Perfect for threading stainless steel, alloy steel, iron and tough metal workpieces.
Main application fields include auto parts, mechanical molds, hardware fittings, aerospace small components and electronic hardware.
For factories pursuing stable threading quality and low tool consumption, HSS cobalt machine taps are a cost-effective long-term machining solution.
