Izar 3120 — Metric Machine Tap (HSSE-V, TiN) — Straight Flute, DIN 371 (M3 → M10)

Izar 3120 — Metric Machine Tap (HSSE-V, TiN) — Straight Flute, DIN 371 (M3 → M10)

High-performance multipurpose machine tap for general threading in production and CNC machines

The Izar 3120 is a DIN 371 metric machine tap manufactured from high-alloy HSSE-V and supplied with a TiN surface finish in standard metric sizes (M3 → M10). Designed as a straight-flute, reinforced-shank machine tap, the 3120 is a true multipurpose threading solution for production shops that need reliable thread forming in a range of materials and hole types.

Why this tap

• Izar 3120 machine tap — HSSE-V substrate with TiN coating for longer tool life.

• DIN 371 straight-flute geometry with reinforced shank for stability on machine threading operations.

• Multipurpose — intended for general threading in common steels, stainless, cast and non-ferrous materials when using correct cutting fluids and feeds.

Geometry & benefits

• Straight-flute (DIN 371) design: Straight flutes provide a robust cutting edge and simpler chip formation, making the 3120 a dependable choice for general machine tapping on lathes, milling heads and tapping machines. The straight flute is especially tolerant of variable machine conditions and easier to resharpen or re-coat than complex geometries.

• Reinforced (overflow) shank per DIN 371: DIN 371 taps are made with a reinforced shank for improved strength and reduced breakage risk — this improves spindle stability and repeatability when threading up to the recommended thread depths. That reinforced shank makes the 3120 well suited to automated production where reliable tool life is essential.

• Chamfer / lead geometry for general use: DIN 371 machine taps are offered with standard chamfer/lead lengths appropriate for through and many blind-hole applications; the 3120 is positioned as a “multipurpose” series in Izar’s catalog so it balances easy starter entry and consistent thread forming across a range of hole depths. Use spiral taps when you specifically need chip extraction for deep blind holes — for general through-hole and short blind-hole work the 3120 is ideal. 

• HSSE-V substrate + TiN coating: The high-speed steel with vanadium (HSSE-V) gives toughness and wear resistance, while the TiN surface finish reduces friction and increases wear life — a reliable combo for higher throughput production runs and mixed-material shops.

Typical uses / applications

• Production threading of steel, alloy steel, stainless steel, cast iron and common non-ferrous materials (use recommended lubricants and feeds for each material). 

• CNC tapping and machine-head tapping where a reinforced shank and predictable chip form are needed.

• General shop use where a single, robust machine tap is required across multiple part families.
