Hand Tap set of 3 pieces ISO 529 HSS-G - M 12 x 1.75 | VÖLKEL
Hand Tap set of 3 pieces ISO 529 HSS-G - M 12 x 1.75
Use this hand tap set for workshop and maintenance tapping where a staged cutting sequence improves control and surface finish. The execution follows ISO 529.
Use the taps in sequence and keep the tool aligned to the hole axis so the final tap defines the functional thread profile. The thread designation is M 12 x 1.75.
- Cut internal threads manually with a progressive tap sequence for controlled lead-in and finishing.
- Use a suitable tap wrench and change taps in sequence to reach the final thread form.
- 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 Use cutting fluid suited to the workpiece material and keep the tool clean and protected after use.
- Spreads cutting load across the staged sequence for better manual control
- Enables controlled chip transport when cutting fluid and reversal are managed
- Fits typical tap holding systems appropriate to the tool type
- Helps you maintain process control across single parts and small batches
- Keeps tool handling straightforward during tool change and inspection
Drawbacks
- Limited suitability for very hard materials unless a dedicated execution is specified
- Requires additional time for tool changes compared with a single tap process
- Confirm the thread designation and ensure the hole is prepared and deburred.
- Clamp the workpiece so the hole axis stays stable while you tap.
- Mount the first tap of the set in a suitable tap wrench and align it to the hole axis.
- Apply cutting fluid suited to the workpiece material.
- Start the thread with steady torque while maintaining alignment.
- Change to the next tap in the sequence when the lead-in is established.
- Use the finishing tap to bring the thread to the final profile.
- Clean the thread and the tools, then protect the cutting edges for storage.
- 3 pieces: hand taps as specified in the set
- Tool type: Hand tap set
- Standard: ISO 529
- Tool material: HSS-G
- Thread system: ISO metric
- Tolerance class: 6H
- Why is a hand tap set used instead of a single tap
- Use a set when you want a staged cutting sequence that starts the thread smoothly and finishes the profile with controlled torque.
- What tool do you use to drive the tap
- Use a tap wrench that holds the square drive securely and lets you maintain alignment to the hole axis.
- What preparation is required before you tap the thread
- Prepare the core hole to the correct size for the thread designation, remove burrs, and add a small lead-in chamfer so the tap can start without side load.
- How do you control chips and cutting fluid during tapping
- Use cutting fluid suited to the workpiece material and clear chips regularly, especially in deeper holes or tougher materials, to prevent chip packing and tool overload.
- Where can you find additional technical information for this execution
- Use the following PDF for reference on hand tapping handling: Technical information hand taps as PDF
- How do you reduce risk of tap breakage
- Keep alignment stable, avoid side load at entry, and stop if torque rises sharply so you can inspect hole preparation, lubrication, and chip evacuation.
- Where can you find more product and application information in the VÖLKEL catalog
- Use this catalog for additional details and related items: VD 23 catalog as PDF
- How do you inspect the thread after tapping
- Check that the thread is clean, that the start is not damaged, and that the functional fit matches the mating component used in your assembly.
