3倍径U钻钻头为中短款的U钻，其最大的有效深度为3倍径。
产品特点：
1高效率：由于工作时转速高所以其钻孔效率高，跟传统的麻花钻相比，其效率是麻花钻的两倍以上
2低成本：由于产品采用可换刀片式的钻头设计，更换钻头只需要更换刀片即可，同时U钻钻头具有很高的加工效率，综合起来就能够大幅的降低人力成本
3高精度：跟传统的麻花钻钻孔相比，因为麻花钻在人工操作时中心孔、以及钻头重磨时都有偏差，所以钻出来的孔精度低，而U钻的钻孔精度可以保证在±0.1mm之间，从而大幅的提升钻孔的精度。
4无重磨：麻花钻在钻削一段时间后变钝就需要进行重磨，而U钻采用的是可更换刀片式的设计在刀片破损以后只需要更换刀片即可，从而无需再重磨钻头，耗费人力时间。
5适用性强：U钻的钻片根据不同的规格可以应用于铸钢件、铸铁、合金钢、不锈钢、铝合金等材料
