Machine Nut Tap FZ HSS-G - Tr 10 x 2 VÖLKEL, mã 79108, phù hợp cho gia công ren trong.
The VÖLKEL Machine Nut Tap FZ HSS-G is designed for producing precise metric trapezoidal threads Tr 10 × 2 according to DIN 103. With its Form FZ geometry – featuring a long thread section, short lead, and back clearance – this tap allows full cắt ren in one pass, making it ideal for lỗ thông and production environments. Made of precision-ground HSS-G, it offers long tool life, consistent accuracy, and reliable performance when machining thép không hợp kim và thép hợp kim thấp or other non-abrasive materials up to 700 N/mm².
A trapezoidal thread (Tr) has a trapezoid-shaped profile that ensures stable flank support and smooth motion. It is typically used in drive and feed mechanisms such as lead screws, vises, or lifting equipment where high load capacity and precise linear motion are essential. The 7H tolerance guarantees a consistent fit with minimal play and excellent repeatability in moving assemblies.

What is Form FZ?
Form FZ describes a tap geometry with a long cutting section and a short lead, allowing for full thread depth to be reached quickly. This design is ideal for lỗ thông and efficient production.
What is a trapezoidal thread used for?
Trapezoidal threads (Tr) are used in applications requiring linear motion and high axial load, such as lead screws, presses, vises, and actuators.
What materials can I use it on?
Non-alloyed and low-alloy steels, and other machinable, non-abrasive materials up to 700 N/mm² strength.
Why is the tolerance 7H important?
The 7H fit ensures a precise, smooth-running thread with minimal backlash, perfect for motion transmission applications.
Can it be used manually?
Yes, it can be used with a suitable Tay quay taro, but machine use is recommended for consistent accuracy and tool life.
