Grades for Steel

Steel	P	P05	P10	P15	P20	P25	P30	P35	P40	P45	P50
		C8	C7 (Light Finishing)			C6 (Semi-Finishing)		C5 (General)
			BK19
							BK65

Grades	ISO	Machining Condition/Application
BK19	P10 ~ P15	Excellent combination of toughness and hardness. Micro-grained tungsten carbide and special processing enable this grade to exhibit high edge strength and wear properties. Excellent choice for low speeds and feeds when machining steel, high temperature alloys, nodular iron and cast iron.
BK65	P30	General purpose, turning, boring and grooving on steel and alloyed cast iron at moderate cutting speeds.

Grades for Cast Iron

Cast Iron	K	K05	K10	K15	K20	K25	K30	K35	K40	K45	K50
		C4	C3 (Semi-Finishing)			C2 (General)		C1 (Roughing)
				BK26
					BK20
					BK19

Grades	ISO	Machining Condition/Application
BK26	K15 ~ K30	Excellent combination of impact and wear properties for moderate to heavy milling at high speeds and feeds on low alloyed cast irons.
BK20	K20	Roughing and general purpose machining of cast iron high temperature alloys and non-ferrous materials. Also utilized in wear applications.
BK19	K20 ~ K30	Excellent combination of toughness and hardness. Micro-grained tungsten carbide and special processing enable this grade to exhibit high edge strength and wear properties. Excellent choice for low speeds and feeds when machining steel, high temperature alloys, nodular iron and cast iron.
