Chamfer die

* High-toughness powder metallurgy steel + TiCN coating – resists chipping and adhesive wear, ideal for stainless/carbon steels. * Pre-ground chamfer angle tolerance ±0.3° – ensures uniform edge geometry across millions of parts, eliminates secondary deburring. * Optimized cutting edge radius – reduces stress concentration at the chamfer root, prevents micro-cracks and premature die failure. * Mirror-polished cavity (Ra ? 0.08 µm) – guarantees smooth material flow, minimizes galling and allows easy part ejection. * Customizable chamfer width & angle – adaptable to head diameters Ø3.0–Ø12.0 mm and various fastener standards (DIN/ISO/ANSI). * Proven at 200+ spm – maintains angle stability under high-speed impact, scrap rate <0.3% in long runs. * Advanced PVD or DLC coating options – boosts surface hardness to HV 3000+, extending die life 2-4× in abrasive conditions. * FEA-validated stress distribution – eliminates fracture at the chamfer lip, even under off-center loading. * 100% dimensional inspection – each die measured by optical comparator and CMM; fully interchangeable with standard cold headers.
