Neil Metals, located in Kolkata, India, has built a solid reputation as a manufacturer and supplier of High Speed Steel T1 Bars, providing top-notch materials for tough cutting and tooling tasks. They’re well-known for their precision in manufacturing and commitment to global quality standards. The T1 grade bars they offer are remarkable for their hardness, wear resistance, and red hardness, making them perfect for high-speed machining jobs. With a strong emphasis on durability, dimensional accuracy, and consistent quality, Neil Metals caters to a variety of industries both in India and abroad, ensuring that their products deliver long-lasting performance and reliability.
High Speed Steel T1 Bars are made from tungsten-based tool steels, primarily consisting of Carbon (0.65–0.80%), Tungsten (17.75–18.75%), Chromium (3.75–5.0%), Vanadium (0.90–1.30%), along with trace amounts of Manganese and Silicon. T1 steel is celebrated for its outstanding hot hardness and cutting capabilities, maintaining its edge even at temperatures over 500°C. It boasts good wear resistance, high compressive strength, and a hardness range of 62–66 HRC after heat treatment, making it one of the most popular conventional high-speed steels out there.

Yes, High-Speed Steel T1 bars can be welded, but it requires specialized techniques like preheating and post-weld heat treatment to prevent cracking and maintain their hardness and strength properties.
High-Speed Steel T1 bars resist corrosion due to the presence of chromium, which forms a protective oxide layer on the surface. This enhances their resistance to moisture and chemical wear, prolonging tool life.
These High Speed Steel T1 Bars are widely utilized in the production of cutting tools like drills, taps, milling cutters, saw blades, and broaches. They shine in high-speed metalworking environments where heat generation is a concern and tool longevity is crucial. T1 bars also find their place in cold work punches, reamers, and die inserts, delivering reliable performance in repetitive, high-stress tasks. Their excellent wear resistance and edge retention make them essential in sectors like automotive, aerospace, die-making, and general engineering, where efficiency and durability are paramount.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
