Tap FANAR GWINTOWNIK M30 NGMM/1 DIN-352D (6H) HSS — M30 threading tool

FANAR GWINTOWNIK M30 NGMM/1 DIN-352D (6H) HSS — M30 threading tool is a machine tap designed for cutting metric M30 threads. Made from high-speed steel and manufactured to DIN-352D dimensional and chamfer standards, this tap provides repeatable, precision threading with 6H tolerance. It is intended for use in industrial and professional metalworking environments where accurate internal threads are required.

Advantages

The HSS construction offers a balance of toughness and wear resistance suitable for a wide range of ferrous and non-ferrous materials. Conformance to DIN-352D ensures consistent thread geometry and reliable engagement in threaded assemblies. The 6H tolerance rating delivers close-fitting internal threads suitable for precision components. The tool's design supports use in machine tapping operations for consistent cycle times and predictable tool life.

Suitable for

• Cutting M30 metric internal threads in steel and alloy materials
• Machine tapping on lathes, milling machines, and dedicated tapping machines
• Production and maintenance operations requiring DIN-standard threads

Key specifications

• Thread size: M30
• Material: high-speed steel (HSS)
• Standard: DIN-352D
• Tolerance class: 6H
• Tool type: machine tap (straight/flute form per DIN)

How to use

Select the correct drill size for the M30 tap drill hole according to standard thread charts, secure the workpiece, and align the tap with the hole axis. Use appropriate cutting fluid for the work material to reduce friction and heat. Operate the tap using the machine's recommended spindle speed and feed for M30 threads, ensuring straight entry and controlled forward/reverse cycles where required to clear chips. Monitor tool wear and replace the tap if thread quality deteriorates or if the tool shows signs of wear.

Usage recommendations

For best results, match cutting speeds and lubricants to the workpiece material, use proper fixturing to prevent deflection, and maintain the tap in good condition. When tapping harder alloys, reduce cutting speed and increase coolant flow. Follow machine manufacturer guidance for tapping feeds and speeds to optimize thread accuracy and tool life.
