Left-hand Reamer

  1. Ideal for Reverse-Threaded Components: Designed for reaming holes in reverse-threaded parts, ensuring proper fit and alignment without damaging threads.
  2. Improved Chip Evacuation: Left-hand rotation efficiently moves chips away from the workpiece, reducing clogging and heat buildup, especially in soft or gummy materials.
  3. Versatile Material Compatibility: Suitable for reaming various materials such as aluminum, steel, stainless steel, brass, and plastics, making it useful across many industries.
  4. Enhanced Precision and Surface Finish: Provides high-quality hole finishes with minimal defects, ensuring improved fit and performance of machined parts.
  5. Reduced Tool Wear: The specialized design and high-quality materials minimize wear, extending tool life in demanding machining environments.

Milling tools

Milling is one of the most varied production processes in metalworking. The process creates precise, complex components that are used in many areas. JINOO provides suitable milling tools for machining different materials depending on the application. The range extends from all-rounders to specialist tools, from conventional roughing cutters to modern HPC/HSC strategies such as dynamic trochoidal milling (GTC) or iMachining (SolidCAM). Different cutting materials are also used for the milling cutters.

Form perfect threads

Threading Tools, for the production of threads have a critical task in common: They are applied at the end of the production chain, when component parts or individual parts are practically finished. JINOO threading tools operate with process reliability – perfect for a demanding machining task at the end of the production chain.

There are several processes to lead to the desired result. No matter if the user decides on fluteless taps, thread taps or thread milling cutters, together with our product management and experienced application technicians we work out the most economical solution for producing a thread.
