▪️ Color: Silver

▪️ Head tap: shallow thread tap, for first tapping Two cone: deep thread tap, used to consolidate tapping
▪️ Use the shallow thread tap first, and then use the deep thread tap. The thread is clear and applicable to most metal materials, hard plastics, wood, etc
▪️Wide range of applications: metal materials, hard plastics, wood and other materials. Alloy tool steel has good processing performance, good strength and toughness, so it is mainly used to manufacture complex thin cutting edges and impact resistant metal cutting tools, and also has higher processing performance
▪️ When tapping, first insert the head tap to make the tap centerline consistent with the drilling centerline. Both hands rotate evenly and apply a little pressure to feed the tap. No pressure is needed after feeding. Each time the tap is rotated, it reverses about 45 degrees to cut off the cutting, so as to avoid blocking. If the tap is difficult to rotate, do not increase the rotation force, otherwise the tap will break.
