Product Description
Komatsu motor grader blade and cutting edge for GD535 GD555 GD655 GD705 GD9555
Our cutting edges and grader blades are engineered to complement each other in demanding soil cutting, scraping, and leveling operations. Through professional quench-tempering processes and precision CNC machining, these wear parts achieve excellent mechanical properties, with surface hardness ranging from 320 to 520 HB (HRC44-52). Backed by 35 years of manufacturing experience and strict ISO9001-9002 quality control systems, they offer exceptional wear and impact resistance, effectively avoiding bending and breakage. Replacing worn parts with our precision-fit blades reduces machine resistance and significantly improves working efficiency in harsh environments.
Our Komatsu motor grader blade, also named grader cutting edge and moldboard wear plate, is a core wear spare part for Komatsu GD535, GD555, GD655, GD705, GD955 series motor graders. Manufactured strictly matching original OEM part numbers like 232-70-12143, 23B-70-31271, these grader blades deliver stable cutting performance for road leveling, ditch digging, slope shaping, airport ground finishing and municipal maintenance projects.
