规格范围：D6-D32
特点说明:比普通螺纹铣刀的刃数多1-2刃（一般为5-6刃，多则8刃），高刚性和高强度设计，难加工材料的铣销切削效率高，使用寿命高。
适用范围：适用于高硬度≥HRC40、高强度钢材、譬如高合金钢、镍基合金、粉末治金材料的螺纹加工。
客户需要提供的资料：被加工材料及硬度、螺纹规格、螺纹深度、通盲孔情况、柄部形式和其他特殊要求。可根据客户需求非标定制。
Specification: D6-D32
Features: 1-2 flutes more than common thread mill (usually 5-6flutes, sometime 8 flutes), good rigidity δ strength design, high cutting sufficiency of difficult processed-materials, longer life.
Application: Suitable for thread-processing of materials whose high hardness is over HRC40, and high strength steel, such as high alloy steel, nickel alloys, powder metallurgy materials .
Information that customer needs to provide: Processed materials and hardness, thread specification and precision, through/blind holes, shank types and other special requirements.
