The low-priced machine tap for processing alloyed and high-alloyed steels (stainless steels), as well as rust-resistant and acid-resistant steels. Also suitable for processing conventional steel materials up to a strength of 850 N/mm².
- Tool geometry precisely tailored to stainless steel with increased clearance angle
- Extra homogeneous cutting edge rounding for a high process reliability and longer service life compared to comparable machine taps
Notice
- Sufficient coolant and lubricant must be added when cutting threads.
- For the machine tap/material assignments, see the overview tables
