Tap, FANAR M 6x0.5 DIN-371C R45 HSSE-PM HL MASTERTAP (6HX)

FANAR MASTERTAP M 6x0.5 DIN-371C R45 HSSE-PM HL is a precision hand tap for cutting metric internal threads M6 x 0.5. Produced from HSSE-PM (high-speed steel produced by powder metallurgy) and finished with an HL coating, this DIN-371C 6HX tap is intended for general purpose threading, repair work and small-batch production where consistent thread geometry and tool life are required. The R45 chamfer and 6HX tolerance designation support reliable thread-forming entry and controlled fit in a range of materials.

Advantages

This tap combines a high-performance HSSE-PM substrate with an HL surface finish to offer improved wear resistance and thermal stability compared with conventional HSS hand taps. The DIN-371C form and R45 chamfer provide a balanced lead for hand tapping, reducing the effort needed to start threads and improving alignment. The 6HX tolerance gives a slightly tighter thread fit suitable for repair and production applications where restored or precise mating is important.

Suitable for

• Cutting M6 x 0.5 metric internal threads by hand
• Repairing damaged threaded holes where nominal M6 fit is required
• Small-batch or maintenance threading tasks in workshops
• Use in a variety of metals and some non-metallic materials compatible with HSSE-PM tooling

When it may not be suitable

This hand tap is not intended for high-volume automated tapping on CNC machining centers or rapid production operations where machine taps optimized for high spindle speeds and through-coolant designs would perform better. It is also not suitable when specific proprietary coatings, extreme corrosion resistance, or specialty geometries (such as deep-fluting or extra-long lengths) are required but not provided.

Key specifications

• Thread size and pitch: M6 x 0.5
• Tap form: DIN-371C
• Chamfer/lead: R45
• Tolerance class: 6HX
• Material: HSSE-PM (powder metallurgy high-speed steel)
• Surface finish: HL
• Intended use: hand tapping

How to use

Select a properly sized drill for the M6 x 0.5 thread, secure the workpiece, and ensure the hole is clean and free of chips. Mount the FANAR M6 tap in a suitable tap wrench, align it square to the hole, and apply steady axial pressure while turning clockwise to start the thread. Use cutting fluid appropriate for the work material, advance one to two full turns, then back off about half a turn to break chips. Continue this cycle until the full thread depth is reached. After threading, reverse the tap fully and clean the hole of chips and residue.

What to consider before purchase

• Confirm the required thread size and pitch (M6 x 0.5) and that 6HX tolerance is appropriate for mating parts.
• Verify hand tapping is the intended application rather than high-speed machine tapping.
• Consider material compatibility with HSSE-PM tooling and whether the HL surface finish meets wear/resistance needs.
• Check that DIN-371C form and R45 chamfer align with your process for hole entry and chip control.

Usage recommendations

Use appropriate cutting fluid, maintain chip clearing by periodically reversing the tap, and avoid excessive side loads to extend tool life and ensure accurate M6 x 0.5 threads when hand tapping with this FANAR MASTERTAP.
