  • 产品描述
    • Commodity name: Modular Drill
    • 材料: P (Carbon Steel, Alloy Steel, Pre-hardened Steel, Tool Steel),K (Cast Iron, Nodular Cast Iron)
    • It excels in drilling cast iron, steel materials, and other demanding applications—such as situations with poor machine tool rigidity or low spindle power.
    • Featuring an optimized flute design and a unique "I"-shaped transverse edge, it delivers exceptional centering capability, significantly enhancing both the surface quality and dimensional accuracy of hole machining.
    • Featuring a unique chip flute design, it delivers superior chip breaking and evacuation performance, ensuring stable tool operation during deep-hole machining—with maximum drilling depths reaching up to 14xD.
    • The tool features a specialized sub-micron grain blank matrix, enhancing its wear resistance. The coating is a composite layer primarily composed of AICr, offering exceptional hot hardness and delivering outstanding wear resistance when machining cast iron and steel materials.
