Thread Tap FANAR GWINTOWNIK M11 NGMM/3 DIN-352 HSS 6H

FANAR GWINTOWNIK M11 NGMM/3 DIN-352 HSS is a solid high-speed steel (HSS) tap designed to cut M11 metric internal threads. Manufactured to DIN 352 with tolerance class 6H and NGMM/3 geometry, this tap is suitable for manual tapping and machine tapping operations. It is intended for use in general steel and similar materials, providing consistent thread profiles for mechanical production, maintenance and repair tasks.

Advantages

The solid HSS construction delivers good wear resistance and heat tolerance for interrupted and continuous cutting. Compliance with DIN 352 and the 6H tolerance class ensures dimensional accuracy and interchangeability of produced threads. The NGMM/3 flute and chamfer geometry facilitate chip evacuation and reduce risk of jamming during tapping. The tap’s design supports both hand and machine operation, offering versatility across workshop environments.

Suitable for

• Cutting M11 metric internal threads in general steel
• Workshop maintenance and repair
• Small-series mechanical production and prototyping
• Hand tapping and machine tapping operations

Key specifications

• Thread size: M11
• Material: high-speed steel (HSS), solid
• Standard: DIN 352
• Tolerance class: 6H
• Geometry: NGMM/3 (straight flutes, defined chamfer)
• Application: internal metric threads

How to use

Select appropriate clamping and alignment to ensure the tap enters the hole squarely. Use a correctly sized pilot hole for M11 tapping according to standard drilling charts for a 6H thread tolerance. For hand tapping, apply steady, even pressure and a suitable cutting fluid; turn the tap forward several turns then back slightly to break chips. For machine tapping, set correct spindle speed, feed and use rigid toolholding to maintain alignment. Clean the hole and remove chips before final assembly.

Usage recommendations

Use cutting fluid appropriate for steel to improve tool life and surface finish. For blind holes, periodically retract the tap to clear chips. Inspect the tap for wear or damage before use and replace when flutes or cutting edges become dull to maintain thread quality.
