YELLOW RING Mũi taro máy DIN 376 Form C 40° Spiral Flute HSSE - M 20 x 2.5

This tap is a DIN 376 Mũi taro máy with a special Form C and a 40° RSP (Right Spiral). It's designed to cut ren hệ mét ISO of size M 20 x 2.5 in a single pass. Unlike Mũi taro ren tay (tạo ren trong), which are often used in sets, this tap is optimized for machine use, enabling fast and precise thread production.

Who is this Specialist For?

This YELLOW RING Mũi taro máy is ideal for you if you:

• Regularly machine lỗ bít in aluminum or aluminum alloys, where efficient chip evacuation is crucial.
• Also need to machine other long-chipping materials such as certain plastics or long-chipping steels.
• Work in series production and value high process reliability and tool life.
• Are looking for a reliable solution for metric threads M 20 x 2.5 that requires the highest precision (tolerance ISO 2 / 6H).

Tapping threads in long-chipping materials, especially in lỗ bít, poses a significant challenge. Long chips can get entangled, clog the tap, and in the worst case, lead to tool breakage or thread damage.

The YELLOW RING Mũi taro máy solves this problem through its special geometry (Form C / 40° RSP) and its 2 flutes:

• Form C (Chamfer lead): The chamfer lead ensures a pulling cut that optimizes chip formation and allows for easy cutting.
• 40° RSP (Right Spiral): The helix angle of the flutes actively carries the chips upwards out of the blind hole, preventing chip clogging.
• 2 Flutes: A reduced number of flutes creates larger chip chambers. This is particularly advantageous for long-chipping materials, as there is more space for the resulting chips, meaning efficient evacuation and a lower risk of clogging. This significantly increases process reliability.

With this tap, you minimize the risk of scrap and tool breakage, save time, and achieve perfectly formed threads every time.

This YELLOW RING tap stands out due to specific features that provide you with direct advantages in your daily work:

• Optimized for Aluminum and Long-Chipping Materials: The combination of Form C (chamfer lead) and the 40° RSP (Right Spiral) is ideal for soft, long-chipping materials. The chamfer lead ensures a clean cut, and the strong helix angle of the flutes effectively evacuates chips from the drilled hole.
• HSS-E Material – Highest Heat Resistance and Toughness: Made from HSSE (High-Speed thép with Cobalt), this tap offers significantly improved wear resistance and hot hardness compared to conventional HSS. This means for you: Longer tool life, even at higher cutting speeds and temperatures, as well as increased fracture resistance. You benefit from fewer tool changes and reliable production.
• Perfect for lỗ bít: The special geometry with the right spiral is predestined for lỗ bít. Chips are controlledly evacuated upwards, drastically reducing the risk of chip accumulation and associated tool breakage in tight drilled holes.
• High Precision according to DIN 376: The nominal size M 20 x 2.5 and the tolerance ISO 2 / 6H ensure precise thread production according to common industry standards. Tolerance 6H is a standard tolerance for metric threads with normal fit. Compliance with the DIN 376 standard stands for quality and reliability.
• Robust All-thép Construction: The total length of 140 mm and the shank diameter of 16 mm with a 12 mm square drive are designed for stability and secure tool clamping in the machine.
• Upper Price Level – An Investment That Pays Off: Although this tap is in the upper price segment, this is reflected in its outstanding quality, durability, and process reliability. The longer tool life and reduction in scrap quickly make the investment profitable. You are buying a tool that consistently delivers high performance and increases the efficiency of your production.
