UNC Spiral Flute Tap Set | AIMS Industrial

Product Features

• 6G-12" HSS-Co5 (Cobalt) UNC Spiral Flute machine tap set.
• Cobalt HSS taps are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
• Spiral Flute taps are designed primarily for machine tapping of blind holes.
• They produce the best results 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.
• Unified National Coarse thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
