TaeguTec Expands Ceramic High-Speed Milling Range

10 November 2025

High-speed machining of heat-resistant aerospace alloys (HRSA) has advanced significantly with the arrival of the expanded CERAMIC-SFEED product line from TaeguTec. As a world-leading innovator in cutting tools, this significant expansion from TaeguTec now includes ceramic-brazed end mills and MAXI-RUSH head types. The new additions have already demonstrated exceptional performance for demanding applications in the aerospace and power generation industries.
Coated with the advanced TC3030 SiAlON ceramic grade, the CERAMIC-SFEED product line offers innovative milling solutions for high-speed and high-feed machining of heat-resistant alloys. The extended lineup provides excellent heat resistance and maintains high-temperature hardness throughout machining. The tools feature unevenly spaced cutting edges and a high helix angle, ensuring exceptional machining performance and prolonged tool life when processing nickel and cobalt alloys. The innovative edge geometry, uneven flute spacing, and high helix angle allow end users to process these challenging materials at cutting speeds of up to 1000m/min.
The newly expanded product line includes several specialised tool types. The MXCRF series features a 6-flute, corner radius ceramic brazed head compatible with MAXI-RUSH holders. Ideal for shouldering, facing, and ramping applications, the 6-flute corner radius ceramic end mill can perform high feed machining in shallow depth of cut conditions with enhanced productivity.
Also new is the CRFB 6. This 6-flute corner radius ceramic brazed end mill series is well suited for shouldering, facing, and ramping applications. These new arrivals are complemented by the existing CRF 4 and CRF 6 ceramic end mills with 4 and 6 flutes, respectively, while the high-feed CRH 4 ceramic end mill provides another versatile solution designed for facing and ramping applications.
A key innovation in the expanded line is the ceramic-brazed construction method. Ceramic-brazed end mills with carbide shanks provide superior rigidity compared to full ceramic shanks, minimising vibration during operation due to the stronger grip. Additionally, the ceramic-brazed MAXI-RUSH heads offer compatibility with various shank options to accommodate a wide range of machining conditions.

The TC3030 ceramic grade used in these tools maintains its hardness at high temperatures, greatly exceeding the performance of carbide. While carbide tools lose hardness as temperatures rise, ceramic tools preserve their integrity even as the nickel alloy workpiece begins to soften. This capability enables the tools to operate effectively at temperatures where the workpiece becomes red-hot, facilitating dynamic rough machining at staggering speeds and feeds. TaeguTec recommends cutting speeds of 300 to 1000m/min for optimal performance, a deviation that depends on the application.

Looking at the specific dimensions of the new arrivals, the MXCRF 6-flute brazed head end mills are available in 10, 12 and 16mm diameters with a respective corner radius of 1, 1.5 and 2mm. The 40-degree helix, 6-flutes and the high-performance TaeguTec TC3030 grade make the new MXCRF a series unparalleled by its rivals.

Complementing the MXCRF, the new 6-flute CRFB 6 brazed end mill is available in diameters of 6, 8, 10, 12, and 16 mm, with corner radii ranging from 0.5 to 2 mm and an overall length from 50 to 83 mm. Alongside these new arrivals, the existing CRF 4 and CRF 6 ceramic end mills have identical dimensions to the new CRFB 6, with an effective flute length (APMX) ranging from 4.5 to 12mm.

The CERAMIC-SFEED line is primarily designed for HRSA roughing operations in aerospace and power generation components, with technical specifications indicating astounding performance on nickel and cobalt alloys. However, the range is not recommended for titanium alloys or stainless steel machining.
