Grade applications

Grade

Recommended application

UBT05

Drill, endmill and burr are recommended. Especially suitable for cutting non-ferrous metal and graphite (coating is needed)

UBT10

Ultrafine grain size, with good wear resistant. Higher wear resistant endmill and engraving tools are recommended. Suitable for cutting PCB and plastic

UBT20F

Drill and endmill are recommended. Suitable for cutting general steel (HRC<48), grey cast iron, stainless steel and heat resistant alloy

UBT20

Drill and endmill are recommended. Suitable for cutting stainless steel, heat resistant alloy and cast iron

UBT25

Ultrafine grain size, high cobalt content with excellent hardness and toughness, endmill and reamer are recommended, especially suitable for cutting steel(HRC:45-55), aluminum alloy and titanium alloy

UBT30

Suitable for making punching of moulds, tools and anti-vibration boring bar etc
