CoroReamer 435 and 835

December 13, 2012

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.

Related Glossary Terms

  • coolant

    coolant

    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • reamer

    reamer

    Rotating cutting tool used to enlarge a drilled hole to size. Normally removes only a small amount of stock. The workpiece supports the multiple-edge cutting tool. Also for contouring an existing hole.

  • tolerance

    tolerance

    Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
