- 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
- Sufficient coolant and lubricant must be added when cutting threads.
- For the machine tap/material assignments, see the overview tables
