Machine Tap GREEN RING DIN 371 Form C 39° Spiral Flute HSSE - M 10 x 1.5

This tap is the optimal choice for a wide range of machine applications. Its most important features that set it apart are:

• Application for Blind Holes: The spiral flute of the tap effectively moves chips upwards out of the hole, preventing the thread from becoming clogged.
• GREEN RING Quality: The symbol stands for a universal tool that is suitable for a wide range of materials with a strength of up to 1000 N/mm².
• HSSE Material: The alloy of High-Speed Steel with Cobalt is particularly heat-resistant and wear-resistant, ideal for tough applications.
• Tolerance ISO 2 / 6H: This tolerance class is the international standard for metric internal threads. It ensures a good fit and smooth assembly.
• DIN 371 Form C: This guarantees a standardized design that offers high process reliability and dependability in series production.

A machine tap is easy to use if you follow these steps:

1. Step 1: Prepare the workpiece. Drill a core hole in your workpiece with the correct diameter for the M 10 x 1.5 thread. Make sure the drilling depth is greater than the desired thread length.
2. Step 2: Prepare the tool. Clamp the tap securely into the machine (e.g., a CNC milling machine or a drill press with a suitable chuck).
3. Step 3: Cutting process. Set the correct speed and feed rate. Begin the cut with a steady feed and ensure sufficient cooling to maximize the tool's service life.
4. Step 4: End the process. Once the tap has reached the desired depth, stop the feed and retract it. The spiral will convey the chips upwards during this process.
5. Step 5: Inspect. Check the finished thread with a suitable thread plug gauge to ensure the dimensions meet the requirements.

Q: What is the difference between a tap for blind holes and one for through holes?

A: Taps for blind holes have a spiral flute that conveys chips upwards out of the hole. Taps for through holes have a straight or slightly left-hand spiral flute that pushes the chips forward and out of the hole.

Q: What does the 6H tolerance mean?

A: The 6H tolerance is the standard tolerance for metric internal threads. It ensures a good fit with most screws that have a 6g or 8g tolerance.

Q: What is the advantage of HSSE material?

A: HSSE is a High-Speed Steel alloyed with cobalt. This increases its hardness, heat resistance, and wear resistance, making it ideal for machining tougher materials and for higher cutting speeds.

Q: Can I use this tap manually?

A: No, this machine tap is primarily designed for machine use due to its geometry (especially the spiral) and short lead. For manual use, a hand tap set is recommended.

Q: What is the purpose of the GREEN RING marking?

A: The GREEN RING marking is a universal VÖLKEL labeling system. It indicates that the tool is suitable for a wide range of materials with good machinability up to a strength of 1000 N/mm².
