HPD-SUS TWIST DRILLS
JOBBER
Application
Designed for 4D ~ 5D drilling in stainless
steels, mild steels,aluminium, aluminium alloy,
aluminium die cast, copper, copper alloy,
etc.
Advantage
High helix-sharp cutting edges to avoid built-up
and to be suitable for high performance drilling.
Reinforced web and jobbers length-increasing
rigidity and suitable for 4D ~ 5D drilling.
High vanadium HSS-EX material with superior
TiN coating - higher speed and feed, longer
service life.
High quality-good surface finishes, high productivity
and weeding second operation.
品名：高速鋼加長麻花鉆頭
用途：
用于加工4-5倍長徑比的孔，可加工不銹鋼、鋁合金、壓鑄鋁合金、銅及銅合金等。
優點：
1、高螺旋的切削刃可避免產生積屑瘤，并可用于高性能的鉆削。
2、刃口增強，可用于4-5倍長徑比的深孔加工。
3、高釩的優質高速鋼材料，并經TiN涂層，可高速高進給加工，使用壽命長。
4、加工的產品質量高，表面光潔度好，效率高，不需要二次操作。
