UM Nu-Roll Tap for Ultra-Small Diameter Threads

Product catalog summary
Product Overview:
The document provides detailed information about the UM Nu-Roll Tap (UM-NRT) designed for ultra-small diameter threads, starting from S0.5. It highlights the tap's ability to produce high-quality threads with minimal burrs due to its special thread form.

Features:
  • The UM-NRT features a CrN coated surface that offers low friction, excellent wear resistance, and anti-fusing properties, ensuring consistent durability.
  • It utilizes powder metallurgy HSS (CPM) for high wear resistance and toughness, providing stable tapping performance.
  • The tap's design includes a rigid neck portion to resist breakage, based on end mill expertise.

Specifications:
  • The recommended tap limit corresponds to JIS class 4H5 internal thread standards, but does not guarantee thread limit for the internal thread after tapping.
  • Various dimensions and types are listed, with specific stock items and prices provided.

Recommended Cutting Conditions:
  • Cutting conditions vary based on work material strength, machine, and holder.
  • Recommended tapping speeds are provided for different materials such as low carbon steels, stainless steels, aluminum, and zinc alloy castings.

Performance Data:
  • In-house tests show the UM-NRT can tap over 10,000 holes in soft steel, commonly used in HDD base plates and consumer electronics.
  • Performance in stainless steel (SUS420) also shows excellent tool life.

Usage Instructions:
  • Use safety equipment during operation and avoid touching cutting edges and chips with bare hands.
  • Stop using the tool if it becomes dull or if abnormal sounds or vibrations occur.
  • Ensure proper tool selection and dimension checks before use.

Additional Information:
  • Tool specifications are subject to change without notice.
  • Recommendations for drills and reamers for UM-NRT are provided, with references to a general catalog for more details.
