TECWERK Hand tap set M2.5 x 0.45 HSS ISO2 (6H) — 3-piece, DIN 352

A hand tap set M2.5 x 0.45 HSS for cutting metric ISO threads in through and blind holes, designed for workshop and maintenance use

• HSS construction for durability
• ISO2 (6H) tolerance for precise threads
• Three taps: taper, intermediate, plug
• Suitable for steels up to 900 N/mm²

Consistent industrial tolerances for secure assemblies

The set provides ISO2 (6H) tolerance in accordance with metric standards, which ensures repeatable thread quality and reliable fit for standard screws and bolts. By conforming to recognised norms, the taps reduce rework and rejected assemblies in production or repair tasks. The M2.5 x 0.45 designation is ideal where small, precise metric threads are required; maintaining the correct tolerance class improves load distribution and prevents premature loosening in assemblies.

Robust high-speed steel for demanding materials

Made from HSS, the tools combine toughness with wear resistance, enabling machining of steels with a tensile strength up to approximately 900 N/mm². The material choice lowers the risk of premature edge wear during repeated hand tapping operations, offering longer service life compared with standard carbon-steel taps. The shank Ø 2.8 mm provides dimensional stability when clamped in a tap wrench, aiding straightness during manual cutting and reducing the chance of breakage.

Three-step tapping sequence for reliable results

The 3-piece configuration — taper (starter), intermediate and plug (finishing) — divides the cutting forces across stages, which reduces torque on each individual tap and improves chip evacuation in both through and blind holes. This sequence produces a smoother root profile and a cleaner thread form, simplifying assembly and increasing the service life of the fastened joint. For manual tapping tasks, the staged approach is particularly effective in preventing tap fracture and ensuring controlled thread formation.

Practical applications and workshop handling

Designed in line with DIN 13 Blatt 1 and supplied as a DIN 352 style set, the tools suit general workshop maintenance, small-batch production and precision repair work where metric ISO threads are required. The set is intended for hand operation with a tap wrench and performs well in both through-hole and blind-hole situations.
