Advantages of Thread Mill with 3 Flutes
Our 3-tooth thread milling cutter is a high-efficiency and high-precision CNC threading tool designed for mass production and standard thread machining. Adopting a professional 3-tooth staggered cutting structure, it perfectly balances cutting stability, machining efficiency and thread surface finish, solving the low-efficiency defect of single-tooth cutters and the severe vibration & tooth chipping problems of full-tooth cutters. Ideal for precision thread processing of carbon steel, stainless steel, alloy steel and aluminum alloy, it is the preferred standard tool for batch thread production in the machinery manufacturing industry.
The three-tooth sequential cutting design realizes step-by-step roughing and finishing: the first tooth removes most of the machining allowance, and the second and third teeth precisely trim the thread profile. This layered cutting method greatly reduces single-side cutting resistance, effectively suppresses tool vibration and tool wear, and ensures consistent thread accuracy and smooth surface.
Core Advantages
- High Machining Efficiency: The 3-tooth collaborative cutting mode boosts processing efficiency by nearly 3 times compared with single-tooth thread mills, supporting 1-2 passes forming for standard threads, greatly shortening production cycle.
- Excellent Stability & Anti-vibration Performance: Balanced cutting force distribution avoids severe jitter of small-diameter tools (such as M6), effectively prevents tool breakage and tooth chipping, and improves tool service life.
- Superior Thread Surface Finish: Precision grinding tooth profile ensures complete thread shape and smooth flank surface, meeting high-precision assembly requirements of IT6-IT7 grade threads.
- High-rigidity Integrated Structure: Made of ultra-fine grain solid carbide with integral molding technology, featuring high hardness, high wear resistance and strong impact resistance.
- Professional Anti-stick Coating: Equipped with TiAlN/TiSiN premium coating, which effectively reduces cutting heat and friction, prevents chip adhesion, and adapts to long-term continuous mass processing.
- Dedicated Fixed Pitch Design: Standard pitch customization, accurate tooth spacing, no thread pitch error, suitable for standardized batch production.
Product Advantages VS Other Thread Mills
- More efficient than single-tooth thread mills, suitable for mass production instead of trial processing.
- More stable and durable than full-tooth thread mills, no severe vibration or tooth breakage for medium-depth threads.
- Higher cost performance, stable precision and long service life, reducing tool replacement frequency and production cost.
