Sandvik Coromant has introduced two CoroReamer solid carbide reamers designed with dedicated geometries and internal coolant to meet requirements for a high surface quality finish and close tolerances with process security.
CoroReamer 435 is suitable for a wide range of different materials while CoroReamer 835 is recommended for steel and stainless materials when optimum performance is needed.
The reamers are available in spiral flute design for through holes and straight flute design for blind holes. The diameter range is 3.97 to 20 mm s standard with an achievable hole tolerance of IT7.
These products complement CoroReamer 830 used in larger diameter applications.
