Fullmax solid carbide reamers have long impressed with their outstanding cutting performance on a range of materials – even on hardened steels up to HRC 62. The latest new short version of Ceratizit’s Fullmax is even more stable to use, allowing for higher cutting speeds, with the added advantage of long service life at a cost-effective price.

The reduced length of the short version of the Fullmax solid carbide reamer offers numerous advantages — the very stable tool is characterised by low vibration, resulting in up to 1% higher cutting speeds in the main application areas of steel and cast iron, making it ideal for high-speed machining.

Feed rates can also be increased by 10 to 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. The tool itself also benefits from reduced friction performance, which is noticeable in the longer service life.

Like the universal standard Fullmax reamers, the short versions are characterised by their specialised high-performance coating and sophisticated cutting edge pitch, which help to reduce chatter marks and improve chip formation.

The unequal division, with cutting edges facing each other in pairs, leads to significantly 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.

This is also helped by the targeted coolant supply, which also provides high-performance cutting edge cooling. The Fullmax solid carbide reamer short version can be used on all CNC milling and turning centres. However, its short dimensions make it particularly attractive for use on sliding head lathes.

The short series of Fullmax reamers are available from stock both in H7 tolerance and in 1/100mm increments. Dimensions can be individually configured in the diameter range of 2.96 to 20.05 mm. In addition, preferred ranges for diameters from 4 to 12mm and 16mm are available from stock.

A special feature of the Fullmax short series is that reamers with diameters from 15.97mm upwards are equipped with eight cutting edges instead of the six flutes on smaller diameters. This further improves the roundness of the fit and its surface finish.

Investing in the short version of the solid carbide tool is well worth considering from a financial point of view as well. This is because the substrate savings compared to the standard Fullmax make it more cost-effective to procure. Which means that if the machining volume is low, the user will save money from the point of purchase.
