NO NAME TAP M 2 DIN-371C R45 (6H) HSSE-PM HL MASTERTAP Machine Tap for Metric Coarse Threads, M2 x 0.4 mm, Spiral Point, Through Holes

Threading M2 holes in alloyed steel or stainless parts on a CNC machining center? The NO NAME TAP M 2 DIN-371C R45 (6H) HSSE-PM HL MASTERTAP gets through-hole tapping done fast, with a spiral point that pushes chips forward so you don’t fight clogged flutes. It’s built for production runs where tool life and thread quality matter.

Key specifications

• Tool type: Machine tap for through holes
• Thread standard: Metric coarse, DIN 371
• Nominal diameter: M2, pitch 0.4 mm
• Tolerance class: 6H
• Geometry: Form C (spiral point / gun nose)
• Material: HSSE-PM (powder metallurgy high-speed steel with cobalt)
• Cutting direction: Right-hand
• Overall length: 45 mm, thread length: 7 mm
• Shank diameter: 2.8 mm, square drive: 2.1 mm
• Number of flutes: 2–3
• Surface finish: HL (FANAR geometry)
• Series: MASTERTAP

Why choose it

The HSSE-PM substrate with cobalt delivers high hot hardness and wear resistance, so you can push cutting speeds higher than standard HSS taps. Powder metallurgy ensures a uniform carbide distribution, giving consistent performance across long batches. The HL finish reduces friction and improves chip flow, while the spiral point design is ideal for through holes—chips are ejected ahead of the tap, preventing re-cutting and extending tool life.

Ideal use cases

• Tapping M2 through holes in alloyed steels, stainless steels, and cast iron
• CNC machining centers and drilling machines with synchronous tapping cycles
• Production of small precision components: electronics housings, automotive fittings, medical devices
• Job shops needing a reliable tap for mixed material batches

Good to know

For blind holes, use a spiral flute tap instead. Always use a suitable cutting fluid to maximize tool life. The tap conforms to DIN 371, which specifies dimensions for machine taps with reinforced shank. Store in a dry place to prevent corrosion.
