The Ceratizit Fullmax universal solid-carbide reamer is now available in a short version. Offering even greater stability, the Fullmax short variant allows for higher cutting speeds, with the added advantage of long service life and a lower price.

With its reduced length, the Fullmax solid-carbide reamer offers numerous advantages. Firstly, the tool is very stable and characterised by low vibration, resulting in up to 10% higher cutting speeds in the main application areas of steel and cast iron. Secondly, feed rates can increase by 10-20%.

This combination delivers machining times up to 20% faster.

In addition, there are better reaming results in terms of surface finish and dimensional accuracy, reports Ceratizit.

Like the universal standard Fullmax reamers, the short versions are characterised by their specialised coating and cutting edge pitch, which help to reduce chatter marks and improve chip formation. In detail, the unequal division, with cutting edges facing each other in pairs, leads to reduced deviations in circularity and cylinder shapes. The increased angle differences reduce the tendency for the tool to oscillate and form chatter marks.

Thanks to the flute-shape opening angle adapted to the new pitch, there is sufficient space for optimised chip removal, even on long-chipping materials. The targeted coolant supply provides further assistance. Although the Fullmax short-version reamer is suitable for deployment on all CNC milling and turning centres, its reduced dimensions make it particularly attractive for use on sliding-head lathes.

The short series Fullmax is available from stock in H7 tolerance and 1/100 mm increments. Dimensions are individually configurable in the diameter range from 2.96 to 20.05 mm.
