FAQ
Questions Buyers Ask
What is the difference between full-profile and V-profile threading inserts?
Full-profile inserts cut the complete thread form including crest and root — one pass profile is guaranteed, programming is simpler, and finish is better, but each insert fits one specific thread pitch. V-profile (multi-point) inserts use a universal V geometry and can cut multiple pitches with infeed control, offering flexibility at the cost of setup complexity.
Which threading insert for stainless steel?
Use PVD-coated grades with sharper edges for stainless steel threading — they reduce work hardening and built-up edge, producing cleaner threads. For steel, CVD-coated or uncoated grades perform well at higher speeds.
