M12 x 1.5 mm HSS Fine Pitch Hand Tap Set — 2-Piece G38339 GEKO
A set of two hand taps for cutting and repairing M12 x 1.5 mm metric fine pitch internal threads. The tools are made from HSS high-speed steel and manufactured to DIN 2181, which ensures consistent thread dimensions and profile in both workshop and service conditions.
Tool features
HSS high-speed steel
HSS (high-speed steel) is an alloy with increased hardness and wear resistance that retains its cutting properties even as the temperature rises during tapping. This translates into a longer tool life than carbon steel, particularly when working in structural and alloy steels.
DIN 2181 compliance
The DIN 2181 standard defines the dimensional tolerances and geometric requirements for taps used on metric fine pitch threads. Tools made to this standard are compatible with ISO thread fits, which is important in applications requiring precise joints.
Two-stage tapping process
The set contains a taper tap (No. 1) and a finishing tap (No. 2). The taper tap starts the cut and guides the tool into the hole, reducing cutting resistance. The finishing tap brings the thread to its final size and profile. Splitting the work between two tools reduces the risk of tap breakage and improves the surface quality of the thread.
M12 x 1.5 mm fine pitch thread
A 1.5 mm pitch (instead of the standard 1.75 mm for M12) means a greater number of threads per unit of length. This results in a joint that is more resistant to vibration, allows finer adjustment on setting components, and makes the tap suitable for thin-walled parts where a standard pitch could weaken the material.

Applications
The set is intended for tapping holes in the following materials and industries:
- Structural and alloy steel — machining in the workshop and in production
- Non-ferrous metals (aluminium, copper, brass) — tapping lighter structural components
- Cast iron — thread repair in machine housings and cast parts
- Selected plastics — tapping in materials of suitable hardness
- Automotive — rethreading cylinder heads, engine blocks and suspension components
- Hydraulics — cutting threads in fittings and valves that require a fine pitch
- Precision engineering — manufacture and repair of setting and adjusting components
- Machine servicing and repair — rethreading damaged internal threads
How to use
Choosing the pilot hole diameter before tapping
Before tapping M12 x 1.5 mm, drill a hole 10.5 mm in diameter. A hole of the wrong diameter overloads the tap or produces an incomplete thread profile. This figure can be checked against a tapping drill size chart (approximate formula: hole diameter = nominal diameter − pitch).
Order in which to use the taps
Start with the taper tap (marked with one line or the number 1) and finish with the finishing tap (two lines or the number 2). Changing the order risks damaging the tool or producing an incorrect thread profile. When tapping, use a suitable lubricant — tapping oil or cutting paste — which reduces friction and extends tool life.
