Description:
6542 high speed steel tap provides high hardness, good durability, abrasion resistance, and excellent cutting performance. 9SiCr alloy tool steel die provides superior hardness, durability and abrasion resistance for durability.
Tap & Die Set can precisely cut, repair, or clean threads. Straight flute taps pass through holes and shallow blind holes to remove chips downwards. Round dies are suitable for threads like rods, bolts, screws, pipes, axles and can also be removed from bolts or threaded rods. Widely used in most metals, iron, copper, zinc, alloy steel, polished steel, stainless steel etc.
Tap & Die has a clear thread without burrs and is the right hand tapping direction. Thread dies are designed with conical lock holes for a strong locking force that will not loosen The uncoated tools only have a basic board and are suitable for a wide range of applications.
The die is used with a die stock wrench (sold separately). Insert the tightening screw in the middle of the wrench into the slot of the die and tighten it. Machine taps are used with drill press, tapping machines, CNC, milling machines. Use appropriate cutting lubricant or oil for better quality threads and durable taps & dies.
Tip: Please control the speed according to the hardness of the material. The harder the slower the speed. Tapping requires even pressure First, drill a hole with the twist drill bit, then tap with the thread tap. Tapping angle must be 90 degree vertical and stable
