Adopt GU ultra-fine grain substrate and TiAlSiN high performance nano coating.
Special angle and reduced neck design
High precision edge diameter precision, high precision head contour, high precision cutter Handle (H5).
Suitable for precise deep hole machining of hardened steel, pre-hardened steel and other materials (hardness HRC≤65)

GST series cover GSTC and GSTS series products, are made by precision grinding and have high dimensional accuracy and surface quality. Matched with a variety of tool holders, they are particularly suitable for parting and slotting of small parts.

Suitable for high performance processing of titanium alloys.
The new titanium alloy milling grade is adopted, which has significant improvement in wear resistance and bond resistance.
Special corner radius treatment, improve the cutting edge strength and sharpness, effectively reduce the vibration caused by corner radius.
The use of enhanced large helix angle design and unequal tooth pitch can reduce the harmonics produced by cutting, and eliminate bad chatter.
A professional 5-edge design has been added, designed to exceed the productivity of 4-edge endmills.
