Competence Reaming and Fine Boring

Precision tools for reaming and fine boring of bores are the core competence of MAPAL. The company is continuing to write its success story related to this area that started with the "original reamer" in 1954. 
Thanks to decades of experiences and continuous further development and optimisation, MAPAL can offer its customers the optimum tooling solution, perfectly tailored to the complexity of the machining operation and the precision requirements.
Next to tailor-made custom solutions, MAPAL offers a broad standard programme of tools for reaming and fine boring.​​​​​​​

    For every workpiece material up to diameters of 315 mm

    Along with the diameter and required bore tolerance, the workpiece material is the most important selection criterion for the appropriate reamer. 
    The programme from MAPAL includes, along with tools for machining steel, inox, cast iron and aluminium, also solutions for the cost-effective, reliable reaming of titanium, super alloys, plastics and composite materials.

    High-performance coatings

    The coating on the cutting edges is a vital factor for the tool life and optimal machining results. 
    MAPAL offers a large selection of substrates and coatings, each matched to the related machining case.
    The state-of-the-art inhouse coating plant is one decisive factor to provide optimum coatings.

    Reconditioning in original quality

    Re-ground reaming tools and cutting inserts that achieve a machining performance of up to 100 percent compared to new tools represent an important control lever for production costs.
    For this reason MAPAL offers tool reconditioning in the form of re-grinding and re-coating in manufacturing quality. 
    And that includes comprehensive services: If required, MAPAL organises the collection and delivery of the tools and guarantees standardised original quality worldwide.

  •  State-of-the-art manufacturing facilities form the basis of the high manufacturing precision at MAPAL.

    Latest production equipment

    3D design and simulations form the basis for the manufacture of MAPAL tools. The data are transferred via interfaces to the related machining centre that forms part of the state-of-art range of machinery available on site. In this way MAPAL reaming tools are produced to the highest quality requirements with monitoring and control by experienced staff. 
    Precision and effectiveness are guaranteed.

    Custom solutions

    Special machining tasks require special tools. For this reason MAPAL offers custom reaming tools individually tailored to the requirements of the customer. 
    Requirements are met optimally with special lead geometry and coatings as well as multi-stepped tools. 
    Combination solutions with other tool technologies from MAPAL can further increase the productivity and reduce non-productive times.
