Company Profile

Shenzhen OPT Cutting Tool Co., Ltd.  one of the leading manufacture in China, specializes in developping and producing carbide and PCD diamond tools.

Advanced Step Reamer Technology | One-Pass Precision Machining
Step reamers combine roughing and finishing operations into a single tool, featuring primary cutting edges for material removal and secondary edges for precision sizing. The stepped configuration ensures coaxiality between diameters while reducing cutting forces through distributed load sharing.
Technical Advantages:
Simultaneous multi-diameter machining improves positional accuracy
Helical or straight flute options for optimal chip control
Laser-processed PCD cutting edges available for non-ferrous materials
Rigid shank designs (straight or Morse taper) minimize vibration
Tool life 3x longer than standard reamers in demanding applications
