Walter is expanding its range of turning tools with new Tiger·tec® Gold grades WMP20G and WMP30G, designed for turning bright steels in the ISO M material group. The grades are suitable for a wide range of austenitic, ferritic, martensitic and duplex stainless steels where machinability varies and cutting conditions are often demanding.

The microstructure of the carbide used in the new turning insert grades has been designed to balance tool body toughness and cutting edge wear resistance. In practice, this means the insert can better withstand interrupted cuts, notch wear and edge chipping, while still offering good wear resistance in continuous cutting. Walter Tools’ patented multilayer Tiger·tec® Gold CVD coating supports this package by improving resistance to both flank and crater wear.

Walter is expanding its Groov·tec™ GD parting and grooving system with new toolholders and insert options aimed at more stable and better-controlled grooving operations. The patented double-sided serration on the GD26 insert increases the contact area between insert and holder, improving clamping rigidity and reducing insert movement during cutting, especially under demanding conditions.

The Groov·tec™ GD range covers axial and radial grooving, parting-off and internal grooving applications. The line has been supplemented with new holders, geometries and sizes, such as 8 mm inserts for heavier-duty applications. The system is ideal where reliable chip control and consistent quality are required in groove and parting operations.

The tangential WT26 system for Swiss-type automatic lathes is being expanded to cover a broader range of turning, grooving and threading applications. The compatibility of different insert types with the same toolholder simplifies tool management and reduces setup times. Precision-ground inserts support stable cutting and consistent surface finish even at small diameters. WT26 tools feature a unique 3D-printed coolant nozzle whose channel geometry is optimized to direct coolant efficiently and precisely straight to the cutting zone.

Turning holders designed for ISO-standard insert geometries use the side-clamping SmartLock solution known from Walter DX18 grooving tools. In Swiss-type automatic lathes, the insert can be changed without removing the holder, speeding up changes and improving machine uptime. The solid design of the turning holder increases rigidity and repeatability, especially in series production. The tools have three coolant channels that provide both top and bottom coolant supply directly into the cutting process. This improves chip breaking, facilitates chip evacuation and reduces thermal load, especially when using high-pressure coolant. The new ISO-standard Swiss turning holders are available in 12×12 mm and 16×16 mm shank sizes for CN..12, DN..11 and WN..06 ISO inserts.

The WB system for internal micro turning is being expanded to cover turning in extremely small diameters, down to 0.3 mm. New toolholders for WB micro turning bars have been added to the range: the through-coolant W4280 enables efficient cooling directly at the cutting zone, while the W4291 holder with collet and adjustable through-coolant channels allows coolant control according to the specific application, and the W4282 holder is designed for tools under 2 mm. The eccentric design of the W4282 holder enables effective coolant guidance directly to the cutting edge even with very small tools. At the same time, the design reduces runout caused by orientation errors relative to the turning center, improving tool setup in the machine and ensuring accuracy and repeatability when turning small geometries. All WB holders also feature a dedicated positioning solution for the tool shank that ensures repeatable WB tool orientation in the holder.

The advanced Drion·tec® E-Peak D5150 indexable drill, introduced in autumn 2025, is being expanded to cover diameter ranges Ø9.00–17.99 mm and drill depths of 3xD, 5xD and 8xD. The D5150 is based on a single drill tip geometry suitable for multiple material groups. A rigid body design, optimized flute geometry and precise drill tip mounting support stable drilling even with higher feed rates and greater drilling depths.

The design with replaceable drill tips is particularly advantageous where carbide price significantly affects drilling tool costs. The worn drill tip can be replaced without renewing the entire tool, improving cost control.

The new Xill·tec™ Aero series MC331 and MC333 end mills are designed for general use across different material groups, with a focus on demanding machining of ISO M and ISO S materials, such as aerospace applications. The easy-cutting geometry and optimized flute design enable high feed rates and efficient material removal in both slotting and dynamic milling. The Xill·tec™ Aero series is available in 5- and 7-flute versions, with (MC333) or without (MC331) chip breakers. Unequal pitch cutting edges reduce vibration and improve process stability, extending tool life.

The WK40EA coating used on these tools is a fine-structured, wear-resistant ACN coating that supports tool performance especially in demanding materials and at high cutting speeds.

For hardened steels and other difficult-to-machine materials, Walter is introducing new ISO H series mills such as the MD480, MD780 and MD880 models. These tools emphasize wear resistance, a stable cutting process and high surface quality, especially in finishing.

MD480 series radius end mills are suitable for precise copy milling of complex 3D surfaces. The through-coolant MD780 orbital drill mill is designed for helical interpolation milling to open holes and pocket geometries. The conical MD880 segment radius mills are available in 4- and 8-flute versions and are particularly suitable for fast finishing of 3D surfaces in 5-axis machining.
The WB10TS grade used in these tools is based on a TiAlSiN HiPIMS coating optimized for machining ISO H materials in the 48–65 HRC hardness range. The coating provides high wear resistance and uniform wear, improving process reliability in demanding applications.

The M6420 mill in the Xtra·tec® S3 series is designed for high-feed roughing, combining high metal removal rates with a stable process. The S3 name refers to the tool’s key characteristics: Stability, Supply (of coolant) and Strength. Four-edged, double-sided inserts improve cost efficiency, and their design allows depths of cut up to 2 mm and tooth feeds up to 3 mm. A newly developed flute geometry, for which a patent has been filed, along with corner features that increase insert support, reduce deflection and improve chip control at high feeds.

The body design focuses on cooling and chip evacuation. Up to three optimized coolant channels per insert seat direct coolant efficiently to the cutting zone and increase flow by up to around 48 %, improving heat management and tool life. At the same time, a larger contact area between insert and body increases stability.

Walter is expanding its ConeFit toolholding system with new AB771 adapters designed for direct use in ER collet systems without a separate collet. This simplifies the setup and reduces potential play and runout in the clamping. The widespread use of ER systems makes the adapters an easily applicable solution across different machine tool environments, such as driven tools on lathes. The new AB771 ConeFit adapter is available in ER16–ER32 sizes and supports internal high-pressure coolant up to 80 bar.

The modular design of the ConeFit system allows different milling heads to be used with the same adapter. Since the replaceable cutting head can be changed directly in the machine without remeasuring the tool, it shortens setup times and supports smooth series production. The modular design based on replaceable milling heads offers a cost-effective solution against the general rise in tool prices caused by higher carbide costs.
