In 2021, Metalworking Magazine launched the "Golden Feng Award" second cutting tool product innovation award selection activity. 52 domestic and foreign tool companies and 74 innovative tool products competed on the same stage, and the quality and scale of the participating products reached a new high. In the fierce competition, after the strict evaluation of users, experts, etc., the award-winning products stand out with solid and innovative technology. Walter's innovative spirit lasts for a century, and the award-winning T271X multi-row thread milling cutter is also a representative of its technological innovation, from precision to geometry, from material to coating, from efficiency to cost.
Walter, Germany is famous for its production and sale of blade knives, and has a century of technical accumulation for the production of inserts and insert bodies. In 2007, Walter acquired the German company Prett, which specializes in the production of threading tools and has a century-old accumulation of threading technology.

Technological innovation points
Feature 1: The ultimate knife body manufacturing accuracy
T271X series multi-row tooth thread milling cutter, first of all to ensure the precision of multi-edge, indexable, multi-row tooth cutter body accurate manufacturing accuracy, the accuracy of the cutter body and the accuracy of the thread are directly related, T271X series multi-row tooth thread milling cutter can cooperate with tool compensation for accurate thread milling processing. 4 years of actual sales and customer use has proved the excellent manufacturing accuracy of the tool body, and even without compensation, it can be directly machined to the required thread accuracy with one knife.
Feature 2: Blade with chip breaker groove and the latest coating technology
Another highlight is the introduction of the D61+D67 with state-of-the-art chip breaker slot to the thread milling insert, which makes up for the gap in the market where thread milling inserts are only simple front cutter faces. At the same time, the insert adopts the advanced Tiger Silver® "Silver Tiger" coating technology, which also raises the coating technology of thread milling inserts to the level of turning inserts.
Feature three: freely switchable internal coolant and indexable blade
The knife body is designed with a central cooling system, with radial internal cool holes, accurately sprayed into the machining area of the tip, through the screw in and out of the end face screws, can be freely switched radial and axial, the same knife body to meet the blind hole and through hole smooth chip evacuation and lubrication. The blade has three tips, which can be converted in the same way as the turning insert and the milling insert, and the tool tip can be converted in the same way as the turning insert, and there is no need to repeat the tool, which is extremely convenient to use.
Feature 4: To achieve efficient and low-cost processing
With high-precision cutter body to ensure thread processing accuracy, with advanced insert chip breaker type covering almost all materials of thread milling processing, with the latest "Silver Tiger" coating technology to achieve ultra-high processing line speed, with multi-edge, multi-row teeth indignation to shorten the processing time of thread milling, coupled with indexable inserts greatly reduced the cost of use.
Real-world cases
Founded in 2019 and sponsored by the MetalWorking Magazine of the Machinery Industry Information Research Institute, the "Golden Feng Award" takes "promoting technological innovation and helping manufacturing power" as its mission, aiming to encourage enterprises to innovate products and promote the continuous improvement of China's manufacturing technology level through selection and commendation.
The "Golden Feng Award" Cutting Tool Product Innovation Award has been successfully held for two sessions so far, which has attracted wide attention in the industry. The award is selected by well-known tool companies at home and abroad to declare their most representative products, after user selection, expert review and other aspects of strict screening, and finally selected a number of fair, professional and authoritative award-winning products, has been highly recognized and fully affirmed by the industry, to a certain extent represents the highest level of domestic and foreign tools.
