FAQ
Q1: Can you control the tip angle precisely?
A: Yes, we can control tip angles within tight tolerances using precision grinding equipment.
Q2: Do you support ultra-small diameters?
A: Yes, we can produce micro pointed carbide rods starting from 0.5 mm diameter.
Q3: Which material is better for wear resistance?
A: Higher hardness grades (like K10) provide better wear resistance, while K20/K30 offer better toughness.
