Machine tap DIN 376C M27 x 3 mm — HSS‑Co, 6H tolerance by TECWERK

The Machine tap DIN 376C M27 x 3 mm — HSS‑Co, 6H tolerance is a precision machine tap for producing metric ISO threads in blind holes and medium‑strength steels

• Machine tap DIN 376C Form C HSS‑Co
• Right‑hand 40° spiral for blind holes
• Tolerance ISO2 (6H) for standard fits
• 20 mm shank for secure clamping

Reliable thread quality and consistent fit

The HSS‑Co construction combines heat resistance with toughness, making the tap suitable for machining steels up to approx. 900 N/mm² tensile strength. The specified tolerance field ISO2 (6H) ensures a predictable internal thread fit, which reduces the need for manual adjustment and guarantees interchangeability with bolts and fasteners made to metric ISO standards. This technical consistency supports smoother assembly processes and fewer rejects in serial production.

Designed for blind‑hole tapping with effective chip control

Equipped with a right‑hand 40° spiral, this tap is optimised for blind holes, where chip evacuation is critical. The spiral geometry directs chips away from the cutting zone and helps prevent clogging at the thread root, which in turn lowers the risk of tool breakage and surface damage. The Form C profile and relieved flanks contribute to stable cutting behaviour and predictable thread form, especially when tapping in stopping holes in medium‑strength materials.

Practical compatibility and machine integration

A 20 mm shank provides robust engagement in the toolholder or collet, improving concentricity and reducing vibration during high‑speed tapping. The thread specification M27 x 3 mm and the adherence to DIN 376C enable straightforward substitution in existing production jigs and fixtures. For planners and process engineers, these measurable attributes mean easier integration into CNC tapping cycles and predictable tool life across batch runs.

Productivity benefits and workshop confidence

Using a cobalt‑alloy tap such as this reduces the frequency of tool changes and downtime compared with standard high‑speed steel in tougher steels. The combination of HSS‑Co, spiral design and standard tolerance delivers both performance and repeatability — practical advantages that translate into lower rework rates and steadier output. Metav Werkzeuge’s inventory practices and European distribution help ensure consistent supply and a quality filter that supports reliable procurement for workshops and industry.

FAQ

What materials can be machined with this tap? The TECWERK machine tap is suitable for machining steels up to approx. 900 N/mm² tensile strength and is intended for typical workshop steel grades.

Is the thread produced compatible with standard fasteners? Yes, the tap cuts a metric ISO thread M27 x 3 mm with ISO2 (6H) tolerance, giving a standard internal fit for ISO metric bolts and screws.

Can this tap be used for blind holes only? The design, including the right‑hand 40° spiral, is optimised for blind holes, improving chip evacuation; it may also be used in certain through‑hole operations depending on machining conditions.

What does Form C indicate for this tap? Form C denotes the specific chamfer and cutting geometry defined under the DIN standard, offering a balance between entry chamfer and machine‑use suitability for consistent thread starts.

Which toolholder is appropriate for this tap? A holder or collet suitable for a 20 mm shank and capable of securing the required concentricity is recommended for best results with this tap.
