VÖLKEL Machine Tap Set M4–M10, Form B, extra long (150 mm) with reduced shank
This professional-grade machine tap set is your go-to solution for cutting internal threads in hard-to-reach places. The extra-long 150 mm reduced shank provides superior reach, while the Form B spiral point pushes chips forward for efficient cutting in through holes. Made of premium HSS-E, it ensures long tool life and precision in non-alloyed and low-alloy steels up to 900 N/mm².
Application & Benefits
- For general use in workshop, repair, and production
- Clean threading in through holes thanks to spiral point design
- Extra-long 150 mm shank for deep or obstructed thread positions
- Made of premium HSS-E for consistent dimension and profile accuracy
- For materials up to 900 N/mm², unalloyed and low-alloy steels

Step-by-Step Guide
- Prepare the core hole: Drill the proper diameter and lightly chamfer the entry.
- Clamp and align: Secure workpiece; insert tap and align axially. The long shank provides clearance.
- Apply lubrication: Generously use cutting oil; reapply as needed during cutting.
- Cut the thread: Maintain constant speed and feed. Form B drives chips forward—no reverse needed.
- Inspect: Clean and check the thread using a screw or gauge.
FAQ
Can this set be used on a bench drill?
Yes, as long as the spindle has reverse function or controlled feed. Always ensure good lubrication.
Why is the tool extra long?
It improves accessibility in deep or recessed thread positions—especially useful in assembly or maintenance work.
Is Form B suitable for blind holes?
No, Form B is optimized for through holes. Use Form C for blind holes.
What’s the correct lubrication?
Use cutting oil suitable for steel; for tough steels, use active oils to minimize friction.
What tolerance can I expect?
Threads meet ISO 2 / 6H for standard fit and accuracy.
