Since the late 1990s, solid carbide endmills (SCEM) have become one of the focal points in the metalworking industry. Several factors contribute to this prominence. Firstly, compared to indexable milling cutters, solid carbide endmills (Fig. 1) offer distinct advantages: greater precision, suitability for small-diameter mill designs, and better options for engineering balanced tool structures. Additionally, SCEM outperforms their counterparts made from highspeed steel (HSS), as the harder carbide material provides higher wear resistance and maintains a sharp cutting edge longer, resulting in extended tool life.

Understandably, the known advantages alone were not sufficient to explain the rapid growth of the share of solid carbide endmills in milling products that began in the 1990s. There were additional elements that contributed to the increased use of SCEM in the industry. The advancements in CNC machining technology and the growing interest in high-speed milling (HSM) methods highlighted the need for tools that are suitable for high cutting speeds, and solid carbide endmills perfectly meet these demands. The quantum leap in tool grinding CNC machines and CAD/CAM systems played a crucial role in the major progress and growing popularity of SCEM during that period. This considerable leap forward was a key factor, a real game-changer, which gave rise to a significant breakthrough.

The enhanced capabilities of tool grinding CNC machines enabled substantially increased accuracy and the production of solid tools with high-precision geometries.

CAD/CAM systems enabled the design and manufacturing of endmills with complex geometries that were previously difficult to achieve. Tool grinding simulator software allowed for a virtual analysis of the grinding process, considerably contributing to the precise production of SCEM.
