Product Description

Our milling cutter series covers all core types to address diverse machining needs, with flat end mills, ball nose end mills, and corner radius end mills as the flagship products. Crafted from premium micrograin carbide (grain size: 0.6–1.2μm) and coated with TiN, TiCN, TiAlN, or AlTiN via advanced PVD technology, these solid carbide milling cutters deliver superior wear resistance, high-temperature tolerance, and lubricity. The flat end mills feature a 4-flute design with optimized chip evacuation grooves, minimizing cutting vibration and enabling smooth slotting, profiling, and face milling of steel and alloy workpieces, with dimensional tolerances as tight as ±0.005mm. Our ball nose end mills boast precisely ground spherical tips, ideal for high-precision 3D contour machining in mold and die making, achieving surface roughness as low as Ra 0.2μm. The corner radius end mills effectively prevent edge chipping and extend tool life when machining rounded corner parts, a critical advantage for manufacturing precision components. 
Complementing our milling cutter lineup is our diverse range of drill bits, including micro-diameter drill bits, deep hole drill bits, and twist drill bits, each designed for specific drilling tasks. Our micro-diameter drill bits are engineered for ultra-precise small-hole machining, with diameters ranging from 0.1mm to 3mm. Made from high-speed steel (HSS) or solid carbide, these drill bits feature a reinforced shank design to prevent bending during high-speed drilling, making them perfect for processing circuit boards, precision instruments, and miniature components. The deep hole drill bits are specialized for drilling holes with depth-to-diameter ratios of up to 30:1, a common requirement in aerospace and automotive engine manufacturing. Equipped with internal coolant channels, these drill bits efficiently remove chips and reduce heat buildup, ensuring straight, burr-free holes in stainless steel and alloy materials. Our twist drill bits are the go-to choice for general-purpose drilling, available in HSS, HSS-Co, and solid carbide variants. With a classic spiral flute design, they deliver fast chip removal and stable performance when drilling carbon steel, aluminum, and copper, with diameters spanning from 1mm to 50mm to accommodate different workpiece thicknesses.
