Our milling picks are engineered for installation on milling drums of road milling machines and related equipment. They offer broad compatibility with leading global brands, including Wirtgen, CAT, XCMG, SANY, Bomag, and Roadtec.
These picks are extensively utilized across a wide range of road engineering applications, such as:
Road Maintenance: Milling and repairing damaged asphalt and concrete pavements.
Road Construction: General road milling for asphalt surfaces and base layers, pavement leveling, and material recycling.
Specialized Operations: Trench excavation for public utilities, airport runway maintenance, parking lot resurfacing, railway line milling, tunnel cutting, and road surface texturing.
Ideal for use with Wirtgen road milling machines, cold recyclers, and trenchers, these picks deliver efficient and precise milling performance for diverse infrastructure projects.
The Hengpu series milling picks integrate a premium tungsten carbide alloy tip with a high-strength 42CrMo steel shank, which undergoes a quenching process for superior durability. Our patented innovation lies in the 3D laser-printed ceramic wear-resistant layer.
Advanced Material: Achieving a remarkable hardness of 68-70 HRC.
Superior Bonding: Utilizing a breakthrough metal-ceramic atomic bonding technology, the layer forms an exceptionally tight bond between the tip and shank. This significantly reduces wear at the critical junction point.
Enhanced Durability: The wear-resistant layer excels on hard asphalt surfaces, offering outstanding abrasion resistance.
By increasing milling area and depth while reducing the frequency of tooth replacements, the Hengpu series minimizes labor costs and machine downtime, ultimately maximizing project efficiency and lowering total operating expenses.
Hengpu is a pioneer in industrial wear resistance technology. We have overcome the long-standing industry challenge of balancing extreme hardness with exceptional toughness.
Technical Breakthrough: Our proprietary process solves the interface bonding difficulties between ceramic particles and the metal matrix. This enables 3D printing of wear layers using over ten types of ceramics (including Al₂O₃, ZrO₂, and SiC) with thicknesses up to 4mm.
Optimized Design: The laser-printed layer features 3D raised and recessed structures that ensure even surface wear distribution, precisely matching the designed service life.
Quality Assurance: The entire manufacturing process adheres to stringent international standards, with each tool certified under ISO9001:2008 and GJB9004B-2009 to guarantee stability and reliability.
Innovative Bionic Design: Inspired by pangolin scales, our proprietary wear-resistant technology creates a bionic structure where the ceramic layer fuses deeply (≥1mm) with the substrate. This represents a significant leap forward in material science.
Perfect Hardness-Toughness Balance: The atomic bonding technique merges the hardness of ceramics with the toughness of metal, delivering unparalleled performance, especially on hard asphalt surfaces.
Customizable Solutions: Available in various models (e.g., HP20T2, HP20T2S, HP22T2, HPSN20-13D) with handle diameters of 20mm and 22mm. Custom lengths are available to meet specific equipment requirements.
High-Temperature & Abrasion Resistance: The laser-printed ceramic layer withstands high temperatures and severe abrasion, extending tool life and ensuring superior performance in the most demanding construction environments.
Rapid & Reliable Supply: Manufactured in mature industrial workshop systems to ensure fast delivery without compromising on strict quality control.
