The OSG Metric Forming Tap (Roll) in M2 x 0.4 is a precision threading tool built for engineers and technicians who demand chip-free, high-precision threads in small-diameter fasteners. Crafted for reliable performance in demanding applications, this tap enables strong, accurately formed threads with minimal post-processing.

• Threading Type: Metric forming tap (roll) for chip-free, deformation-based thread formation
• Nominal Size: M2 x 0.4 standard for precise, small-diameter applications
• Material: HSS‑E cobalt for enhanced toughness and wear resistance
• Coating: Titanium Nitride (TiN) coating to reduce friction and extend tool life
• Design: Fluteless geometry that promotes clean chipless forming and minimizes tap stress

Forming taps create threads by plastically deforming the material rather than cutting away metal, delivering stronger engagement and better surface finish. The TiN coating enhances lubricity and longevity in repetitive tapping cycles, while the fluteless design reduces the risk of breakage and improves stability in tight or blind holes. This combination is ideal for high-precision assemblies, electronics enclosures, and lightweight metal components where consistent, durable threads matter.
