carbide button
tungsten carbide button has superior wear resistance and impact
toughness, and similar products with higher speed of drilling and
digging.Series of ball tooth bit passivation using cycle is long,
not to grind the life span of about the same diameter RenPian
grinding head drill bit 5-6 times of life, is beneficial to save
auxiliary working hours, physical labor and reduce workers to speed
up the project.
