After welding, and then sharpening, grinding into 4 Pyramid shape, and then used to knock stone, which is not easy to bad, which is more durable? Model number is D224, I would like to ask you, which should I buy? I'm mainly used for knocking stones.
Knock stone, choose YG8, better impact and abrasion resistance,
YG8C is used on impact drills, which is suitable?
YG8 is suitable for YG6 with higher hardness, but less impact toughness
