三、常见问题 FAQ
本系列钻头的倍径是多少？最大有效钻孔深度是多少？
答：本系列为 8 倍径硬质合金麻花钻，最大有效钻孔深度为对应钻径的 8 倍，表格中的槽长 L3 即为有效切削深度。
本系列钻头的冷却方式是什么？
答：全系列均为内冷结构钻头，支持通过刀柄内部通入切削液实现中心冷却，可有效降低切削温度、提升深孔排屑效率。
表格中 “推荐切削丝锥 / 挤压丝锥” 有什么作用？
答：表格中标注的丝锥规格，代表对应钻头加工出的底孔可直接适配该型号丝锥，用于对应规格内螺纹的攻丝加工，可直接按表选型。
本系列钻头符合什么标准？装夹方式是什么？
答：本系列符合 DIN 6535 标准，采用直柄结构，不同钻径对应标准级柄径，可适配常规 ER 弹簧夹头、侧固式刀柄等装夹。
本系列钻头的几何参数是多少？
答：本系列钻头钻尖角度为 130°，螺旋角为 30°，兼顾钻孔定心精度与切屑排出性能，适合深孔加工。
该系列钻头适合加工哪些材料？
答：涂层硬质合金基体适配碳素钢、合金钢、铸铁等主流黑色金属材料的钻削加工，针对不同材质可对应调整转速与进给参数。
挤压丝锥和切削丝锥的底孔钻头可以通用吗？
答：不通用。挤压丝锥通过材料塑性变形成型螺纹，所需底孔直径更大；表格中已分别标注两类丝锥对应的钻头规格，建议按表对应选型。
