Machine Tap DIN 374 Form C HSSE - FG 2 x 56

• for general use
• machinable materials up to 900 N/mm²
• unalloyed and low-alloyed steels
• for through and blind holes

1. Drill core hole: Drill the core hole for the thread with the correct diameter. You can find the exact size in a thread table for bicycle threads.
2. Prepare the tool: Securely clamp the tap in the machine. Make sure the tool is correctly aligned.
3. Lubrication: Apply a suitable cutting oil before cutting to minimize friction and extend the tool's life.
4. Cut the thread: Start the machine and slowly feed the tap into the hole.
5. Retraction: After the desired depth has been reached, carefully retract the tap.
6. Inspection: Check the cut thread for cleanliness and precision.

Q: What is special about an FG bicycle thread?

A: The FG thread has a flank angle of 60°, which it shares with many other bicycle standards. This can sometimes make correct identification of the thread standard difficult, as mix-ups can happen quickly.

Q: Why should I be particularly careful when working with FG threads?

A: Due to the similarity of flank angles with other standards, it is advisable to use the thread table very carefully. The manufacturer recommends never using force. Attempts to create a screw connection with force can damage the thread and lead to unsafe connections.

Q: What does the material designation HSS-E mean?

A: HSS-E (High Speed Steel with Cobalt) is a high-performance alloyed high-speed steel. The addition of cobalt increases the tool's hardness, temperature resistance, and wear resistance. This leads to a significantly longer tool life, especially when machining materials that are difficult to cut.

Q: What is a thread according to DIN 79012?

A: DIN 79012 is the standard for bicycle threads, which specifies the dimensions and tolerances for these specific threads. The designation FG 2 x 56 stands for the nominal size and pitch of the thread.

Q: Can I also use this tap for other thread standards?

A: This tap is specifically designed for producing FG 2 x 56 bicycle threads. Due to its specific dimensions and pitch, it is not suitable for other thread standards. Using it for unintended threads can lead to inaccurate results or damage to the workpiece.
