Sandvik Coromant recently launched two new reamers. Solid-carbide reamers from the CoroReamer family are the solution when high surface quality finish and close tolerances are required. With dedicated geometries and internal coolant, they deliver superb hole quality and process security.

CoroReamer 435 is a versatile and high performance reamer, suitable for a wide range of different materials.

CoroReamer 835 is 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 3.97-20mm (0.156-0.787 inch) as standard with an achievable hole tolerance of IT7.

These complement CoroReamer 830 used in larger diameter applications.
