Fanar Machine Tap M16 Expanded (D2-111121-0160) - HSS-E Spiral Point Metric Coarse Thread, DIN 376, ISO 2 (6H), Through Hole Threading

On the shop floor, a machinist sets up a CNC lathe to tap M16 threads in a batch of steel flanges. The Fanar Machine Tap M16 Expanded (D2-111121-0160) is the tool that gets the job done quickly and accurately. This spiral point tap is engineered for through holes, pushing chips forward and preventing clogging, which means faster cycle times and cleaner threads.

Why choose it

Built from HSS-E with cobalt, this tap delivers high wear resistance and heat tolerance, making it suitable for a range of steels and cast iron. The spiral point geometry drives chips ahead of the tap, eliminating chip packing in through holes and reducing the risk of tap breakage. With DIN 376 compliance and ISO 2 (6H) tolerance, you get consistent, gauge-accurate threads every time.

Ideal use cases

• Production tapping of through holes in steel components
• General machining in job shops and maintenance departments
• Creating standard M16 coarse threads in flanges, brackets, and mounting plates

Good to know

This tap is intended for machine use with a suitable tapping attachment or rigid tapping cycle. Always use appropriate cutting fluid for best results and tool life. The bright finish provides a clean surface and good chip flow.
