TECWERK machine thread tap MF12×1.25 HSS‑Co, Form B, straight flute

TECWERK MF12×1.25 machine thread tap for production threading of metric fine threads, designed for through holes and a wide range of engineering materials

• HSS‑Co high‑performance cutting material
• Form B straight flute geometry for reliable chip evacuation
• Metric fine thread MF12×1.25, tolerance 6H
• Suitable for steels up to approx. 1000 N/mm²

Consistent fine threads for assembly integrity

The MF12×1.25 metric fine thread specification, made to DIN 13, delivers a reliably tight fit for assemblies where vibration resistance and precise preload are required. Manufactured from HSS‑Co, the tool combines hardness with red hardness stability to withstand higher cutting temperatures; this yields lower tool wear in series production. The tolerance class 6H provides an industry‑standard allowance that simplifies interchangeability and quality control. For engineers seeking repeatable thread quality, the combination of material and tolerance reduces scrap rates and rework.

Efficient cutting geometry that supports throughput

The Form B, straight‑flute configuration with flank relief grinding improves chip formation in through‑hole operations and eases ejection along the flute. This geometry is particularly effective in long‑chipping non‑ferrous metals and malleable cast iron, while also handling steels with tensile strength up to approximately 1000 N/mm². The provided Schälanschnitt for through threads optimises the entry chamfer and initial cutting action, helping to reduce torque peaks and contributing to smoother tapping cycles. As a result, machining times and tool change frequency can be reduced, improving overall operational efficiency.

Practical handling and compatibility for workshop integration

A 9 mm shank diameter allows secure mounting in standard tool holders and tapping machines, offering mechanical stability for automated or manual operations. The tap’s specifications suit a range of production environments, from dedicated threading cells to general workshop use. The tool is compatible with typical tapping speeds for cobalt HSS, and its durability characteristics mean fewer interruptions for replacement. Accessibility of an appropriate shank size and standard metric thread form simplifies tool inventory and reduces set‑up time across multiple workstations.
