Machine taps are made from HSS-E steel with 5% cobalt. This material provides 63-65 Rockwell C hardness for stable thread production. Taps are available in taper, second, and finishing types with diameters from 1 to 52 mm. Thread geometry conforms to ISO metric, imperial, and pipe standards. A 3 to 5 chamfer thread facilitates easy entry into the pilot hole. Spiral point taps feature a 40-degree helix angle flute for efficient chip ejection. These taps are used in CNC machines and pillar drills at speeds of 5 to 15 meters per minute.

Hand and machine dies are produced from high-carbon steel or coated HSS. Their standard diameter for external threads ranges from 2 to 60 mm. Die structure typically has four adjustable segments with a cutting angle of 5 to 15 degrees. Pipe dies with a 55-degree angle suit gas and water pipe threading. Recommended cutting speed for machine dies is 10 to 20 meters per minute. These tools can produce threads with 6H accuracy for taps and 6g for dies. Their service life can reach up to 5000 complete threads, depending on workpiece material.You can order and buy abzar jahan boresh from Iran by contacting us through whatsaap and email.
