Goliath MC Spiral Flute DIN 376 HSS-Co5 Tap Long Series

• HSS-Co Bright Finish Reduced Shank Metric Coarse Spiral Flute Machine Tap.
• HSS-Co Spiral Flute Long Series Tap made to DIN 376 standard.
• Reduced shank taps have a smaller shank diameter than full-diameter taps.
• Reduced shank taps are designed for through-hole applications in materials with high tensile strength.
• Spiral Flute taps are designed primarily for machine tapping of blind holes.
• They are used to the best advantage in materials that produce long continuous chips.
• The right-hand spiral forces the swarf out of the hole and prevents the chips from clogging at the bottom of the hole or in the flutes, which could cause tap breakage or spoiled threads.
• The metric Coarse angle of thread is 60 degrees.
• The crest is flat and the thread has clearance at the root allowing external thread and internal thread to engage well.
• A larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength.
• The major diameter of external thread and pitch is specified by a simple numerical value (most commonly measured in millimetres).
• Manufactured from HSS-Co5.
