MF stands for metric fine thread. It has a smaller pitch than a standard M-thread and ensures more precise and vibration-resistant connections.

DIN 13 defines the ISO metric thread profiles for both coarse and fine threads used in screws and nuts.

DIN 2181 specifies the dimensions and types of hand taps for fine threads.

What does HSS-G mean?

HSS-G means ground high-speed steel, ensuring high precision, smooth cutting edges, and long tool life.

What does ISO 2 / 6H mean?

ISO 2 / 6H describes the standard tolerance class for internal threads, ensuring smooth running and accurate fits.

VÖLKEL Hand Tap Set of 2 Pieces DIN 2181 HSS-G - M10 x 0.5

VÖLKEL Hand Tap Set of 2 Pieces DIN 2181 HSS-G – M 10 × 0.5

The VÖLKEL two-piece hand tap set (DIN 2181, HSS-G) is designed for precise manual cutting of metric fine threads (MF). With a nominal size of M10 × 0.5, it is ideal for unalloyed and low-alloy steels and free-cutting materials up to 900 N/mm². The ground HSS-G construction provides high dimensional accuracy, clean cutting edges, and a long tool life.

Application & Advantages

For general use in workshop and assembly
For materials up to 900 N/mm²
Suitable for unalloyed and low-alloy steels
For through and blind holes
Optimized for manual thread cutting
HSS-G ground – precise cutting geometry and extended service life
Fine thread (MF) – ensures tight, vibration-resistant connections

Step-by-step instructions

Drill the core hole: Drill according to the M10 × 0.5 core diameter chart, deburr and clean.
Fix the workpiece: Clamp securely to avoid misalignment.
Apply cutting fluid: Apply cutting oil or paste to reduce friction.
Use taper tap first: Rotate clockwise evenly to start cutting the thread.
Use plug tap second: Finish the thread accurately without excessive pressure.
Clean and inspect: Remove chips, clean the thread, and check with a screw or gauge.

FAQ

Can I use this set on a machine?
No, it is designed for manual use. For machine tapping, use taps according to DIN 371/376.

What’s the difference between MF and M threads?
MF (fine) threads have a smaller pitch for tighter and more precise fits than standard M threads.

Which order should I use the taps in?
Start with the taper tap, then use the plug tap to complete the thread accurately.

Why choose HSS-G?
Ground cutting edges ensure smooth thread surfaces, long service life, and accurate tolerances.

Is the set sold individually?
Yes, size M10 × 0.5, article no. 26331.
