This high-performance Mũi taro máy from VÖLKEL, manufactured according to DIN 374 Form C, is designed for cutting tapered pipe threads Rc (BSPT). With a short lead (Form C) and precise geometry, it is ideal for producing accurate and leak-proof threads in through and lỗ bít. Made from HSSEit ensures long service life, excellent wear resistance, and smooth cutting results in steels up to 900 N/mm².
Matching holders and lubricants are available separately.

What’s the difference between Rc and R?
Rc refers to internal tapered threads, while R refers to external BSPT threads.
How does the seal work?
The 1:16 taper creates a self-sealing fit without needing additional sealant, though thread tape can be added.
Can it be used for stainless thép?
Only conditionally – for INOX, a TiN or TiCN-coated version is recommended.
What does HSSE stand for?
High Speed thép with cobalt for improved heat resistance and durability.
Can it be used manually?
Yes, but a machine setup provides more consistent precision.
