Mũi taro ren tay (tạo ren trong) set of 2 chiếc DIN 2181 HSS-G ren trái - UNF 5/16 x 24 LH

VÖLKEL Two-chiếc Mũi taro ren tay (tạo ren trong) Set DIN 2181 HSS-G Left-Hand Thread – UNF 5/16 x 24 LH

Restore threads with precision and reliability! The VÖLKEL two-chiếc Mũi taro ren tay (tạo ren trong) set DIN 2181 HSS-G Left-Hand Thread – UNF 5/16 x 24 LH is your go-to solution for manually cutting left-hand threads. This high-quality set is ideal for producing or repairing American fine threads (UNF) in easily machinable materials, whether in lỗ thông or lỗ bít.

Complete Set for Left-Hand Thread Experts

This two-chiếc set is specifically designed for left-hand threads and includes two perfectly matched Mũi taro ren tay (tạo ren trong):

• Taper Tap (lead approx. 6-8 threads): The first tap in the set. Its long lead ensures easy alignment and guidance in the hole, reducing initial cutting force and protecting the tool.
• Plug Tap (lead approx. 2-3 threads): The second tap brings the thread to its final depth and profile, ensuring full accuracy.

Your Advantages

• Left-Hand Thread Specialist (LH): Essential for applications where left-hand rotation prevents loosening or is specifically required.
• Precision Two-Step System: Enables controlled, clean, and material-friendly cắt ren.
• Long Tool Life: Made from ground high-speed thép (HSS-G) for sharp cutting edges and high wear resistance.
• Versatile Use: Perfect for materials up to 900 N/mm², including thép không hợp kim và thép hợp kim thấp.
• Universal Application: Suitable for both through and lỗ bít, ideal for manual use.
• Certified Quality: Complies with DIN 2181 for Mũi taro ren tay (tạo ren trong) and ANSI B1.1 (UNF threads).

Typical Applications

This left-Mũi taro ren tay (tạo ren trong) set is used wherever screws must not loosen under right-hand rotation (e.g., drill chucks, grinding wheels) or where a left-hand thread is structurally required. Common uses include:

• Repairs on machinery, bicycles (pedals), motorcycles, and equipment
• Mechanical engineering, where anti-loosening features are needed due to vibrations or torque
• Maintenance and small series production

What is UNF?

UNF stands for Unified National Fine, a key category of the American Unified Thread Standard (UTS), widely used in the US and Canada. Fine threads like UNF have a smaller pitch than coarse threads (UNC), offering:

• Greater resistance to vibration
• Finer adjustment
• Higher load capacity in thin-walled materials
• Larger thread cross-section

UNF 5/16 x 24:

• 5/16: Thread diameter in inches (approx. 7.94 mm)
• 24: Threads per inch (TPI)

Left-Hand (LH) vs. Right-Hand (RH) Threads

• Right-Hand (RH): Standard direction; screws tighten clockwise.
• Left-Hand (LH): Reverse direction; screws tighten counterclockwise. Used to prevent unintentional loosening from opposing rotation or vibration (e.g., left pedal on a bicycle).

What is ANSI B1.1?

ANSI B1.1 is the American standard for Unified Inch Screw Threads, defining dimensions and tolerances for UN, UNC, UNF, UNEF, and UNS threads, ensuring compatibility with US hardware.

What is DIN 2181?

DIN 2181 is the German standard specifying dimensions and requirements for Mũi taro ren tay (tạo ren trong) for both metric and inch fine threads, especially for two-chiếc sets—a mark of quality.

What does HSS-G mean?

• HSS: High-speed thép, known for hardness and toughness at high temperatures.
• G (ground): Indicates precision-ground cutting edges and flutes for:
• Sharper cutting edges
• Higher dimensional accuracy
• Longer tool life

lỗ thông vs. lỗ bít

• Through Hole: Passes completely through the workpiece; chips can exit freely.
• Blind Hole: Has a bottom; chips must be cleared. The two-chiếc set is suitable for both, with the plug tap finishing the thread to the bottom.

Application:
