Walter has expanded the range of its Thread·tec Omni TD117 Advance blind-hole taps and Thread·tec Omni TD217 Advance through-hole taps, offering manufacturers additional thread profiles and enhanced performance options for various machining applications. The expansion strengthens the company’s portfolio of tapping solutions designed for general mechanical engineering and precision manufacturing environments.
The Thread·tec Omni TD117 Advance blind-hole tap series now includes additional thread profiles based on DIN standards such as G, UNC, UNF and UN-8. It also supports EgUNC and EgUNF screw thread inserts as well as DIN and ANSI profiles including UNC, UNF and UN-8 with STI-UNC and STI-UNF screw thread inserts. These additions expand the range of threading applications that manufacturers can handle using the blind-hole tap system.
Similarly, the Thread·tec Omni TD217 Advance through-hole tap series has been expanded to include additional DIN thread profiles such as G, BSW, UNC, UNF and UNEF. The series also supports EgUNC and EgUNF thread inserts along with DIN and ANSI profiles including UNC, UNF, STI-UNC and STI-UNF screw thread inserts. This wider selection allows manufacturers to address more threading requirements across different machining environments.
Both tapping systems are manufactured using a wear-resistant HSS-E substrate, which provides durability and consistent performance during threading operations. The taps are available in three different performance grades tailored for specific materials and machining conditions.
The WY80FC grade features a universal steam-oxide coating designed to promote effective chip formation and reliable threading performance across a broad range of materials. The WY80RG grade is a high-performance coated variant optimized for machining stainless steel and non-ferrous metals, offering improved tool life and process stability. The WY80AA grade incorporates a TiN coating and is intended for tapping operations in steel and cast iron applications.
The TD117 Advance blind-hole tap incorporates a 40-degree helix angle, which helps ensure efficient chip evacuation from blind holes. This design improves chip flow during tapping operations where chip removal is particularly challenging. The tool also features optimized cutting edge preparation and a specialized micro-geometry that reduces the risk of edge fracture and improves reliability during thread production.
Available in multiple tolerance classes, the blind-hole tap can produce both C and E variants of chamfer forms. An extra-long version of the tool is also offered for applications requiring deeper reach. The tap is capable of producing blind-hole threads up to 2.5 times the nominal diameter, making it suitable for a wide range of mechanical engineering applications.
The TD217 Advance through-hole tap is designed to produce through-hole threads up to three times the nominal diameter. It incorporates an enhanced tolerance position that helps extend tool life across various dimensions and thread profiles. In addition, the tool features an optimized spiral point angle that improves chip evacuation and overall tapping performance.
With these new additions, Walter aims to provide manufacturers with greater flexibility in threading operations while improving reliability, chip control and tool life across different machining environments.
