YG-1 TPKN 43PDSR-GW Milling Insert with PDSR Reinforced Anti-Chipping Edge GW Universal Chipbreaker and TiAlN Nano PVD Coating

TPKN1603PDSR-GW (inch shorthand TPKN43PDSR-GW) YG-1 is authentic Korean-made YG-1 single-sided positive triangular indexable shoulder milling insert, professionally developed for universal medium heavy roughing and semi-finishing of carbon steel, alloy steel, stainless steel and grey cast iron. Equipped with PDSR reinforced anti-chipping edge structure and GW wide balanced multi-material chipbreaker, each triangular insert provides three independent reusable cutting edges to greatly lower single-piece tool consumption cost. Adopting shock-resistant TiAlN nano PVD coated submicron carbide substrate, it perfectly matches TPKN series 90° shoulder mill cutter heads, supporting square shoulder profiling, step surface milling, flat face stock removal and mild-severe interrupted blank processing. Widely applied on vertical & horizontal CNC machining centers for automotive structural forgings, injection mold bases, hydraulic valve blocks and general machinery multi-metal mass milling production.

• Equilateral triangular single-sided structure with 3 independent usable cutting edges, excellent cost efficiency compared with square double-sided inserts, reduces workshop tool inventory expenditure
• Positive rake cutting geometry, effectively disperses cutting impact force, lowers machine spindle load and machining vibration during high-feed heavy stock removal
• PDSR integrated reinforced edge chamfer design, enhances edge strength to resist micro chipping under interrupted cutting of scaled forged and cast blanks
• Exclusive GW wide balanced chipbreaker geometry, extra-large smooth chip pocket splits long curled steel chips into neat short fragments, avoids chip winding and scratch defects on machined surfaces; compatible for both medium roughing and precision semi-finishing
• Dense nano TiAlN multi-layer PVD coating with strong bonding force, outstanding high-temperature wear resistance and anti-BUE performance, thoroughly solves stainless steel material sticking problems
• Ultra-fine submicron WC-Co carbide substrate, balanced hardness and impact toughness, maintains complete edge integrity under unstable interrupted milling conditions
• 3.97mm thick rigid insert body, high structural rigidity without deflection under large radial and axial cutting loads
• Dual international standard naming system (metric TPKN1603 / inch shorthand TPKN43), convenient for global customer order inquiry and unified warehouse inventory management
• Multi-material universal compatibility, one insert covers steel, stainless steel and cast iron machining, simplifies workshop multi-material milling tool setup and replacement

• Mild carbon steel, medium carbon structural steel, alloy structural steel, 304/316 austenitic stainless steel, grey cast iron, ductile iron, low-hardness pre-hardened mold steel
