Machine Tap DIN 371 Form B HSSE 100 mm - M 3 x 0.5

• Create internal threads in pre-drilled holes for fasteners and fittings in mechanical engineering and maintenance.
• Use with a suitable tap holder or a tap wrench, depending on whether you work on a machine or by hand.
• Use in general workshop work and small series production where thread quality and alignment matter.
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Keep the workpiece and tool clean so that thread quality is not affected by debris or burrs.

• Supports repeatable thread quality when the correct execution is selected for the hole type.
• Suitable for workshop and production use across common engineering materials.
• Allows a standardized tapping process with predictable tool handling.
• Tool geometry supports chip evacuation when used with suitable lubrication.

• Incorrect alignment can quickly cause thread damage or tool failure.
• Not intended for extreme high speed tapping without process validation.

1. Confirm the thread standard and choose the correct tool execution for the hole type.
2. Prepare the pre-drilled hole according to your process plan and clean the entry.
3. Clamp the tool in a suitable holder or tap wrench so that it runs true.
4. Align the tool square to the surface and apply a suitable cutting fluid.
5. Start tapping with steady feed and keep alignment constant through the first turns.
6. Advance with controlled rotation while allowing chips to evacuate.
7. Reverse the tool as needed to clear chips without applying excessive load.
8. Stop at the required engagement and withdraw the tool.
9. Clean the thread and verify fit with the mating fastener or a gauge.

How do you choose the correct tap or die for your thread standard?
You identify the thread system and pitch from the drawing and match it to the tool designation. You also select the correct chamfer form for through holes or blind holes.

Where can you find additional technical information relevant to this product type?
For background and selection guidance you can use the following document. Technical information machine taps as PDF

What holder type should you use for reliable alignment?
For machine use you clamp the tool in a suitable tap holder or collet, and for manual work you use a tap wrench or a die holder. You avoid freehand starting where alignment cannot be controlled.

What lubrication should you use during threading?
You use a cutting fluid suitable for the workpiece material and your process. Lubrication reduces friction and supports cleaner chip evacuation.

How do you reduce the risk of a broken tap?
You keep the tool aligned, avoid overloading, and ensure the pre-hole is prepared correctly. If resistance increases you stop and remove chips before continuing.

Can you rework an existing thread with the same tool?
Depending on thread condition you can refresh a thread, but you avoid forcing the tool into damaged profiles. You clean the thread and confirm that the tool enters smoothly.
