Hand Tap set of 3 pieces DIN 352 HSS-G - BSW 1.7/8 x 4.5

• internal BSW 1.7/8 x 4.5 thread production or careful reworking where the existing component defines the thread
• The set supports the full rougher, intermediate, and finisher sequence for controlled manual internal thread production.
• staged manual tapping where separate tap stages are used in sequence
• workshop, maintenance, assembly, and repair tasks with controlled manual tool guidance
• 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 Match thread system, size, pitch, tap stage, holder, and hole preparation before use.

• HSS-G cutting material supports precise hand thread cutting when the tool is aligned and lubricated correctly
• DIN 352 product execution gives a defined tool form for selection by standard and thread designation
• tolerance class medium provides a clear selection reference for the intended internal thread
• separate tap stages support progressive manual cutting instead of forcing one tool to remove all material
• set structure keeps the required hand tap stages together for the same thread designation

• The tool must match the exact thread system, size, pitch, and stage; choose another product in the Threading tools category when one of these criteria differs.

1. Confirm that the workpiece requires BSW 1.7/8 x 4.5 and that the mating part uses the same thread system.
2. Prepare the hole and secure the workpiece so the tap can enter square to the surface.
3. Select the first tap stage from the set for starting the internal thread.
4. Apply suitable cutting oil and start with steady hand pressure.
5. Turn the tool carefully and clear chips regularly without forcing the cutting edges.
6. Continue with the next tap stage until the thread profile is complete.
7. Clean the thread and check fit with the mating part or a suitable inspection method.
