BLACK RING Machine taps (set of 7 pcs.) DIN 371/376 M 3 – M 12

• Cutting of ren trong in steels and common engineering materials within the limits of the chosen execution
• Use for series work, repair tasks, and general machining in mechanical engineering and metal fabrication
• Suitable for lỗ thông and lỗ bít depending on the geometry stated in the product name
• Use with a tapping chuck or suitable collet holder to keep axial alignment during the tapping cycle
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: cắt ren, taro lại ren, and làm sạch ren depending on condition

Lưu ý If the thread is safety relevant, you also check thread quality with an appropriate gauge after machining.

• Supports rework and maintenance tasks without changing the workpiece design
• Defined cutting geometry supports predictable thread form
• Clear variant identification via standard and form in the product name
• Suitable for workshop and series processes when lubrication and alignment are controlled

• Tool life can drop in very hard or abrasive materials if the selected execution is not matched to the application
• Not suitable for high performance applications when process parameters are not optimised

1. Confirm the thread designation, standard, and execution in the product name against your drawing and material specification.
2. Prepare the pre hole and entry chamfer according to your process specification and remove burrs from the opening.
3. Clamp the tap in a tapping chuck or suitable collet holder and set up the cycle so feed stays synchronised with rotation.
4. Apply a suitable cutting Chất bôi trơn cắt gọt ren or coolant for the workpiece material and ensure the entry area is wet.
5. Start the cut with the tool aligned to the hole axis and keep the alignment stable through the first turns or revolutions.
6. Continue the pass while monitoring torque and remove the tool if chips accumulate and increase cutting resistance.
7. Retract the tool, clean chips from the flutes, and inspect the thread before the part moves to the next operation.
