Threading Tools Threading Insert General Features Dimple breaker Indexable inserts l A positive rake angle encourages good chip TME type for external control and reduces cutting resistance. threading l Two tier dimple-style chip breakers evacuate chip smoothly and easily. l M-class tolerance reduces insert cost. New sintered threading insert with special dimple shaped chip breaker l Four available grades cover a wider range of applications. l The LTER type holder is designed for easy Comparison of Chip Control clamping and replacement. TME Insert Work material: 25 CrMo 4 Cutting speed: 100 m/min Threading Holders Pitch: 1,5 mm Competitor‘s ground insert Comparison of Tool Life Cutting Grades for Threading 980 AC225 Multi layer coating 1000 - 950 The AC225 is a carbide insert 900 TiN with a 2 µm multiple-layer coating. Al2O3 This design results in improved Ti(C,N) Tool Life (Work Pieces / Corner) 800 - toughness and adhesion Special 680 ACE-layer resistance making this grade suitable for stainless steel and 600 - general steel. Very tough base material 400 400 - 240 200 - Neue Cermet-Grade T130A AC225 Cermet grade TME insert Competitor‘s ground T130A with 3 cutting insert with 3 cutting corners corners The T130A is a cermet grade containing high TiN with a uniform fine-grain microstructure which results in improved Work Material : X5CrNi1810 (Stainless steel) wear resistance and toughness. Cutting Conditions: vc = 100 m/min Thus, the T130A produces a goods surface finish. Pitch: 1,5 mm 7 Passes Wet F44
