Threading inserts
Full series threading inserts support ISO, UN, NPT, BSPT, TR and other global thread standards with multiple IC sizes and pitches. TiN & TiAlN coated substrates deliver sharp edge, high thread precision, low cutting resistance and smooth chip evacuation. They machine steel, stainless steel and cast iron at regular & high cutting speeds. Matching alloy spring steel threading tool holders boost efficiency & tool life by 30%-50%, with strict inspection cutting defect rate by 80%. Widely used in aerospace, auto parts and precision CNC machining, professional tool selection consultation is available.
