other round tool bit
High cobalt series: M42, M35, rockwell hardness (HRC) 68-70ºC for the cutting of hard processing, ultra high strength materials
For example: stainless steel, titanium alloy, nickel alloy, quenched steel
Steel and other chemical composition complex machining field, is the ordinary tool life
More than 3 to 7 times, can completely replace foreign products

high property Hss-e: M2 with special ingredients, rockwell hardness (HRC) 66-69ºC for cutting of hard processing and high strength materials.For example: carbon tool steel, alloy tool steel, high
Quick tool steel, rolling bearing steel, negative spring, cast steel

Odinary hardness HSS-L: general high speed steel with special composition, rockwell hardness (HRC) 66ºC for medium Cutting of normal strength materials.Examples: iron, copper, aluminum, common carbon tools steel

Low alloy 4241: rockwell hardness (HRC) 61-62ºC with certain red hardness, excellent toughness, thermoplastic
Good performance, usually used in soft, medium strength metal cutting conditions
