Completely new solid carbide reaming tool from KOMET
KOMET DIHART is expanding its solid carbide reaming range with the ‘Fullmax’, a completely revised universal reaming tool. With a new first-cut geometry and coating, it is suitable for use with almost all materials. Fullmax reaming tools are available ex stock in the main dimensions, both in H7 tolerance and in graduations of 1/100 mm.
The reaming specialists at KOMET DIHART have packed all their experience gained from producing previous solid carbide reaming tools into consistently developing these tools further. Their creation is the new KOMET DIHART Fullmax reamer, that brings a host of benefits at a range of technical levels.
The tool's strong points include, for example, the further development of first-cut geometry which is available exclusively for Fullmax tools. The geometry enables a particularly high level of cutting performance in a range of different materials, even in hardened steels up to HRC62.
Particular strengths are demonstrated by the modified spacing of the cutting edges. The uneven spacing chosen with cutting edges arranged opposite each other in pairs produces significantly reduced deviations in roundness and cylindrical shape. The increase in the differences of the angles reduce the tendency of the tool to vibrate and for chatter marks to be created. Because the groove shape and its opening angle has been adapted to the new spacing, there is sufficient space for optimum chip evacuation, even in materials which produce relatively long swarf. Chip evacuation is also supported by the targeted delivery of coolant, which in addition provides substantial cutting edge cooling.
The new design is completed by the universal, high-performance ‘DBG-U’ coating, a TiAlN multi-layered thin layer that was developed for Fullmax. The coating opens up a range of deployment options for this solid carbide reaming tool and, because of its improved wear resistance, contributes to longer tool life.
These characteristics and properties combine to create the kind of precision for which KOMET is known on the market, as well as for its high standards of dimensional accuracy and surface finish quality. Through numerous trials in KOMET's own Tech Centre, users are also provided with valuable recommendations in terms of cutting data suitable for each particular task.
