For over 45 years MicroGroup, part of TE Connectivity, has been manufacturing Biopsy needles and Cutters for the largest Medical Device OEMs. Proprietary manufacturing methods and state of the art equipment allow MicroGroup to lead the pack in component quality, precision, and lead-time. MicroGroup’s ability to resize and centerless grind tubing allows us to create inner/outer components with tolerances of “tenths of a thousandth of an inch” This capability results in optimum component performance at high RPM and reciprocation rates.


Depending on design and intended function, technologies of Multi-Axis CNC Grinding, CNC Turning, specialized EDM processes and Laser welding are strategically used to provide intended geometry and ultimate performance of single and multiple component assemblies.

Some of our typical Biopsy/ Cutter components include:

  • Solid trocars
  • Cannulas
  • Closed end tubes with side apertures
  • Hollow point cutters cylindrical ground and custom profile tips

Electro Chemical GrindingMicroGroup produces the highest quality components and devices to exacting tolerances. Our many years of experience and process improvement have allowed us to perfect the programming and machining of the toughest profiles along with the finest finishes and to give the highest component durability.

To complement our machining technology, MicroGroup has a multitude of other capabilities which far exceed our competition. Our vast array of finishing processes can be used to create many different surface textures and finishes.
