TECWERK machine tap DIN 374B MF 8 x 1 mm — HSS‑Co, tolerance 6H

TECWERK machine tap DIN 374B MF 8 x 1 mm, HSS‑Co, Form B is a straight‑fluted machine tap designed for metric ISO fine threads in through-holes and general workshop or production use.

• HSS‑Co cobalt high‑speed steel
• Straight flute Form B for controlled chip flow
• Tolerance 6H for precise metric fine threads
• Shear cut for reliable through‑threading

Consistent fine threads for repeatable assembly

The HSS‑Co composition paired with the DIN 13 metric fine‑thread geometry ensures a stable cutting edge and long tool life when producing MF 8 x 1 mm threads to tolerance 6H. The precise tolerance class minimises thread variability across batches, supporting predictable fit and reliable assembly in production runs. For shops aiming to reduce rework, this geometry produces consistently formed flanks and thread pitch, lowering scrap rates and improving downstream assembly uptime.

Geometry and chip control that protect the component

Form B straight flutes with flanks relieved enable controlled chip formation and evacuation, especially in through-holes. The integrated shear cut at the chamfer reduces cutting forces at entry, which helps to preserve the surface integrity of the component and reduces torque peaks on the spindle. The result is smoother engagement when tapping through materials and a reduced risk of thread damage in long‑chipping non‑ferrous metals. The tool’s compact shaft Ø 6 mm offers straightforward clamping in common tool holders for machine tapping operations.

Broad material range and workshop applicability

Ground and sharpened for use in steels up to approx. 1000 N/mm² tensile strength, malleable cast iron and long‑chipping non‑ferrous metals, the tap is suitable for many general engineering tasks where metric fine threads are required. The combination of HSS‑Co and the straight‑flute Form B makes the tool tolerant of intermittent machining conditions and suitable for both manual and CNC tapping cycles. For best results, select cutting fluids appropriate to the workpiece material and adhere to recommended spindle speeds for the chosen material class.
