As pressure on global raw material supply chains continues to intensify, manufacturers are increasingly reassessing how cutting tool materials are used throughout the machining process. According to Tungaloy Corporation, carbide remains essential for heavy roughing applications, but its use is not always technically necessary in finishing operations where cutting loads are significantly lower.

In many finishing applications, the focus shifts away from maximum toughness towards process stability, surface quality and efficient material usage. Under these conditions, cermet provides a practical and engineered alternative capable of reducing carbide consumption without compromising machining performance.

Finishing operations typically involve shallow depths of cut, high cutting speeds and continuous or lightly interrupted machining conditions. These are precisely the environments where cermet performs most effectively. Developed from ceramic and metallic components, cermet grades are specifically engineered to deliver high wear resistance, predictable tool life and excellent surface finish in stable machining conditions.

Tungaloy’s cermet range is designed for finishing and light semi-finishing applications in steels and alloy steels. The NS9530 grade provides a balanced combination of wear resistance and toughness for stable finishing operations, while GT9530 is optimised for precision finishing applications where surface quality is critical. The AT9530 grade has been developed specifically for alloy steels, delivering consistent machining performance in continuous cutting conditions.

Rather than attempting to replace carbide universally, Tungaloy emphasises that cermet should be viewed as part of a smarter material allocation strategy. When matched correctly to the application, cermet can help manufacturers reduce dependence on carbide resources, maintain stable productivity and improve overall process efficiency.

High-feed milling places enormous demands on cutting tools. Feed rates, chip evacuation, surface finish and tool life all directly influence machining productivity, making insert design critical to overall performance. With the launch of its new CHASEFEED SRMT insert line, TaeguTec has introduced a solution engineered to overcome the common limitations associated with conventional high-feed milling inserts.

A key advantage of the new SRMT design is its ability to utilise all four cutting edges fully and equally. In many competing insert designs, adjacent cutting edges become exposed to the cutting zone during machining, leading to premature wear and inconsistent performance. TaeguTec’s optimised insert geometry eliminates this issue by keeping neighbouring edges clear of the cut, allowing each corner to deliver reliable tool life and stable machining performance in succession.

Chip control is another major challenge in high-feed milling operations. Poor chip evacuation can result in chips re-entering the cutting zone, damaging workpiece surfaces, causing insert chipping and even jamming the cutter. The SRMT insert addresses this issue with a geometry designed to direct chips efficiently into the gullet and away from the workpiece. This capability improves surface finish and enables the insert to perform effectively across roughing, semi-finishing and finishing applications.

Sharp cutting edges further enhance performance by reducing cutting forces and improving machining efficiency in difficult materials. Higher feed rates can therefore be maintained without compromising tool life or component quality, reports TaeguTec.

The SRMT range is available in 07, 10 and 14 insert sizes, supported by four dedicated chip former geometries covering steel, stainless steel, cast iron, titanium, superalloys and hard materials.

A single cardiac pacemaker contains up to 40 miniature components, while a modern passenger aircraft uses millions of fastening elements. Across sectors ranging from aerospace and automotive to medical technology and electronics, demand for smaller, more precise components continues to grow rapidly. For manufacturers, this trend is driving new levels of complexity in machining and placing greater emphasis on cutting-tool performance.

Cutting tool specialist Walter has invested heavily in tooling solutions specifically developed for small-part machining applications. The company’s portfolio addresses the demanding requirements of Swiss-type sliding-headstock lathes and micro-machining centres, where tolerances are measured in microns and process reliability is critical.

Small-part machining presents challenges that differ significantly from conventional machining. High spindle speeds, thermal instability, vibration and chip evacuation all have a disproportionate effect on component quality when diameters fall below 40 mm. Applications in sectors such as medical technology and aerospace are particularly demanding, often involving titanium alloys, stainless steels and other difficult-to-machine materials.

Walter’s tooling range has been developed to address these challenges across turning, milling, drilling and threading operations. In turning applications, the Tiger tec Gold WPP20G grade delivers the wear resistance and edge stability required for high-speed Swiss-type machining. For milling, Walter’s Xill tec cutters and MD266 Supreme support the production of intricate geometries while maintaining dimensional consistency and reducing cycle times.

The company’s DB133 Supreme micro drill is designed to maximise concentricity and process reliability in small-diameter holemaking, while the TC620 Supreme thread milling cutter helps minimise the risk of tool failure in miniature threading operations.

As small-part production continues to expand, Walter’s combination of precision tooling, application expertise and process support positions the company strongly in one of manufacturing’s fastest-growing sectors.
