Hand Tap DIN 352 Form D HSS-G non-serial form - M 42 x 4.5 | VÖLKEL
Hand Tap DIN 352 Form D HSS-G non-serial form - M 42 x 4.5
Use this hand tap for manual internal thread cutting during repair, assembly, and workshop work where you need direct feel of cutting load. The execution follows DIN 352.
Use steady torque and consistent cutting fluid, and stop if load rises sharply to avoid tool breakage. Form D defines the chamfer and lead-in behavior.
- Cut internal threads manually in prepared holes during repair and workshop work.
- Use a suitable tap wrench to keep the tool aligned and to control torque.
- 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.
- Supports predictable lead-in when you align the tool to the hole axis
- Helps you achieve repeatable internal thread form in workshop conditions
- Enables controlled chip transport when cutting fluid and reversal are managed
- 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
- Not suitable for high-performance machine tapping without controlled guidance
- 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 tap in a suitable tap wrench and keep the tool square to the hole.
- Apply cutting fluid suited to the workpiece material.
- Start the thread with steady torque while maintaining alignment.
- Reverse as needed to clear chips and reduce cutting load.
- Continue until the required thread depth is reached, then reverse out fully.
- Clean the thread and the tool, then protect the cutting edges for storage.

- When should you use a hand tap instead of a machine tap
- Use a hand tap when you need manual control in repair or assembly work, or when machine access is limited and you can keep the tool aligned with a tap wrench.
- 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.
