Take advantage of precise ISO2 (6H) tolerances and durable HSS construction for reliable thread production; the three-stage design reduces tool stress and improves thread quality, while the 22 mm shank ensures stable handling – order the hand tap set directly via Metav Werkzeuge or consult our specialists for application advice.

Hand tap set DIN 352 M27x3 HSS ISO2 (6H) – TECWERK

The Hand tap set DIN 352 M27x3 HSS ISO2 (6H) is a three-piece metric tapping set for cutting M27 × 3 threads in steels up to approximately 900 N/mm², suitable for both through and blind holes.

• HSS cutting material for durable use
• Metric ISO thread M27 × 3, tolerance ISO2 (6H)
• Three-piece set: taper, intermediate, finishing
• For through and blind holes, steels up to 900 N/mm²

Consistent industrial threads with ISO2 accuracy

The set delivers metric ISO threads to ISO2 (6H) tolerance, complying with DIN 352 and referencing DIN 13 Blatt 1, which together ensure interchangeability and repeatable fit in threaded assemblies. This industrial conformity reduces rework and inspection effort: parts produced with the set can be assembled confidently, since the taps cut threads to internationally recognised tolerances. The right-hand cutting geometry contributes to predictable chip formation and regular torque behaviour during manual tapping.

Robust HSS construction for demanding steel applications

Constructed from high-speed steel (HSS), the taps are designed for durability and edge stability when machining ferrous materials. The set is specified for steels up to approx. 900 N/mm², which covers a wide range of structural and engineering steels used in workshops and light production. The 22 mm shank provides solid engagement in standard tap wrenches and holders, helping to minimise wobble and uneven loading during use, thereby lowering the risk of breakage and extending service life.

Three-stage design for safer, cleaner tapping

The three tools—taper (lead), intermediate (plug), and finishing (bottoming)—work in sequence to distribute cutting forces and evacuate chips progressively. The taper tap starts the thread gently, the intermediate tap refines the form, and the finishing tap produces the final thread profile and tolerance. This staged approach is particularly advantageous in blind-hole tapping, where controlled chip removal is essential, and in through-hole tapping, where the progression reduces torque spikes and tool stress.

Practical handling, lubrication and tool care

For dependable results, use suitable cutting fluid and ensure correct alignment of the tap to the hole axis; manual tapping benefits from steady feed and periodic reverse motion to break chips. The right-hand cutting orientation matches standard machining practice. After use, clean chips from flutes and store the taps in protective sleeves to preserve cutting edges. Regular inspection of the cutting lips and flutes will indicate when regrinding or replacement is due, keeping process quality high and downtime low.
