110-Piece Tap and Die Set GEKO G38300
A complete tool set for cutting internal and external metric threads. It covers 34 thread sizes from M2 to M18 with a range of pitches, including fine and coarse options, together with a full complement of die holders and tap wrenches.
Set features
A complete solution
The set includes dies for external threads, plug and taper taps for internal threads, and a full set of die holders and tap wrenches. It removes the need to buy additional accessories for standard metalworking jobs.
Range of thread pitches
Most sizes are available with both coarse threads (e.g. M8 x 1.25mm) and fine threads (M8 x 1.0mm, M8 x 0.75mm). This allows work to the different standards used in automotive, hydraulic and precision engineering applications.
Two types of tap
Taper taps make it easier to start cutting and keep the tool aligned, particularly in hard-to-reach places. Plug taps allow the thread to be finished right to the bottom of a blind hole.
Ergonomic tap wrenches
Three tap wrenches with different ranges, plus a reversible ratchet model, speed up work and reduce fatigue when cutting many threads. The ratchet allows cutting without having to remove the tool.

Plug taps (34 pcs)
Used for cutting or re-cutting internal threads right to the bottom of a blind hole. They have a shorter working section than taper taps.
Taper taps (34 pcs)
They make it easier to start a thread thanks to their gradual lead-in. Used first when cutting new threads or in through holes.
Accessories (8 pcs)
- M3-M12 tap wrench – universal type for smaller diameters
- M6-M20 tap wrench – reinforced type for larger diameters
- Reversible ratchet tap wrench – speeds up thread cutting
- M2-M9 die holder – precision type for small diameters
- M10-M18 die holder – heavy-duty type for large diameters
Applications
- Repairing damaged or stripped threads in steel and aluminium components
- Cutting new threaded connections in welded structures
- Automotive service work – repairing threads in engine blocks, cylinder heads and gearboxes
- Maintenance and upgrading of industrial machinery
- Fitting hydraulic and pneumatic systems
- Metalworking in mechanical workshops and manufacturing plants
- Building prototypes and small-batch equipment
- Cutting fine threads in precision components and measuring instruments
Difference between coarse and fine threads
Coarse threads (e.g. M8 x 1.25mm) are the standard in most structural applications. Fine threads (e.g. M8 x 1.0mm or M8 x 0.75mm) are used where greater pull-out strength, better sealing or threading in thin walls is required. They are common in automotive applications (e.g. in aluminium cylinder heads) and high-pressure hydraulics.
Use and maintenance
Preparing a hole for an internal thread
Before cutting a thread, a hole must be drilled to the core diameter of the thread. For M8 x 1.25mm this is a 6.8mm drill bit, and for M10 x 1.5mm an 8.5mm bit. Exact diameters are given in standard reference tables, or they can be calculated using the formula: nominal diameter minus thread pitch.
Thread cutting technique
When cutting internal threads, turn half a revolution forwards, then a quarter of a revolution backwards to break the swarf. Using a cutting fluid (machine oil, emulsion) makes cutting significantly easier and extends tool life. For hard materials or deep threads, it is worth starting with the taper tap and finishing with the plug tap.
Storage
Store the tools in a dry place, protected from moisture.
