## Summary description

FANAR M4 DIN 371B (6HX) hand/plug thread tap in HSSE-PM high-speed steel with TiCN coating, designation 1400-HT. Conforms to DIN 371B for plug taps, tolerance 6HX. Designed for cutting M4 metric threads in through and blind holes, providing wear resistance from HSSE-PM substrate and TiCN surface treatment for longer tool life in machining and maintenance tasks.

## Long description

FANAR Thread Tap M4 DIN 371B (6HX) HSSE-PM TiCN 1400-HT is a hand/plug tap designed for cutting M4 metric threads in through and blind holes. Manufactured from HSSE-PM high-speed steel and finished with a titanium carbonitride (TiCN) coating, this DIN 371B plug tap provides a 6HX tolerance suitable for standard assembly and maintenance tasks. It is intended for manual tapping and light machine tapping where DIN 371B geometry and the specified tolerance ensure reliable thread form and fit.
Advantages
The HSSE-PM substrate delivers improved toughness and wear resistance compared with conventional high-speed steels, reducing chipping and breakage risk during intermittent tapping. The TiCN surface treatment increases surface hardness and lowers friction, extending tool life and improving chip evacuation over longer production runs. DIN 371B geometry combined with the 6HX tolerance gives consistent thread quality and compatibility with standard M4 fasteners.
Suitable for
 Cutting M4 metric threads in through holes
 Cutting M4 metric threads in blind holes with prepared chamfer
 Manual hand tapping and light machine tapping
 Maintenance, workshop repairs and small-batch production
Key specifications
 Thread size: M4
 Tap type: DIN 371B plug/hand tap
 Tolerance class: 6HX
 Material: HSSE-PM (powder metallurgy high-speed steel)
 Coating: TiCN (titanium carbonitride)
 Designation: 1400-HT
 Intended use: through and blind holes
How to use
Select an appropriate drill size and prepare the hole according to standard drilling recommendations for M4 threads. Secure the workpiece and align the tap square to the hole axis. For hand tapping, use a suitable T-handle or tap wrench and apply steady pressure while rotating the tap clockwise to cut. Periodically reverse the tap by a partial turn to break chips and improve evacuation. Use cutting fluid appropriate for HSSE-PM tools to reduce cutting temperatures and improve surface finish. For blind holes, monitor tap depth and withdraw to clear chips to avoid chip packing.
Usage recommendations
Use correct drill size and cutting fluid, avoid excessive side loads, and choose hand or machine tapping techniques compatible with DIN 371B plugs. Inspect threads after tapping for fit and clean chips from the hole before assembly.
