Carbide drill Classification and brand

YG3X (K01) hardness ≥91.5 in tungsten-cobalt titanium alloy has the best wear resistance, but the impact toughness is poor, suitable for cast iron non-ferrous metals and their alloys, fire steel, alloy steel small section of high-speed finishing.

YG3 (K05) hardness ≥90.5 wear resistance second only to YG3X, more sensitive to impact and vibration, suitable for cast iron non-ferrous metals and their alloys when continuous cutting fine car semi fine car, fine car thread and reaming

YG6A(K10) hardness ≥91.5 is a fine grain alloy, good wear resistance, suitable for cold hard cast iron, non-ferrous metals and their alloys semi-finishing, also suitable for fire steel alloy steel semi-finishing and fine processing.

YG6 (K15K20) hardness ≥90 wear resistance is higher, but lower than YG3, impact and vibration resistance is better than YG3X. Suitable for semi-finishing and finishing of cast iron, non-ferrous metal and alloy, non-metallic materials at medium cutting speed.

YG8 (K30) hardness ≥89.5 high strength, impact resistance, shock resistance is better than YG6, but wear resistance and allowed cutting speed is lower. Suitable for low speed rough machining of cast iron, non-ferrous metal and alloy, non-metallic materials.

K0 type: used for embedded system is one word hard alloy brazing sheet (24.26.28.30.32.34.36.38.40.42, etc.),

Type T3: Alloy drill bits (T308, T310, T313) used to insert rotary drilling strata

Type T1: Used for mounting in rotary drilling medium hard rock bits (T105, T108, T110)

K1 type used in embedded system cross and x type carbide drill bit (K117. K119. K120. K122. K124. K12)
