From the heart of Addis Ababa, Tariku Metals proudly serves as your dedicated manufacturer and supplier of industrial-grade materials. Our commitment is to Ethiopia’s growing industrial sector, providing reliable tools that empower progress. We specialize in supplying High-Speed Steel M35 bars, a product chosen by professionals who demand exceptional performance and durability in their cutting and machining tools, ensuring that local industries have access to world-class quality right here at home.
What truly sets these M35 bars apart is their sophisticated composition, a careful balance of tungsten, molybdenum, vanadium, and a significant 5% cobalt addition. This specific formula gives the steel its remarkable red-hardness, meaning it retains its strength and cutting edge even when it gets extremely hot from friction during high-speed operations. This results in a bar stock with superior wear resistance, exceptional strength, and a long-lasting performance that stands up to the most demanding tasks.

Yes, High-Speed Steel M35 can be welded, but it requires careful control of heat and preheating. Post-weld heat treatment is often necessary to restore its hardness and performance.
Yes, High-Speed Steel M35 bars can be customized in terms of dimensions, shape, and surface finish. Machining and heat treatment processes can also be tailored to meet specific performance requirements.
High-Speed Steel M35 bars should be stored in a dry, cool environment, away from moisture and extreme temperatures. They should be kept on racks to prevent contact with corrosive materials.
Consequently, these bars are precisely what you need for creating high-performance cutting tools that must perform under pressure. They are expertly forged into drill bits, end mills, taps, and saw blades that excel in machining tough materials like stainless steel and high-temperature alloys. Beyond cutting tools, their strength and heat resistance also make them ideal for critical components in manufacturing equipment, such as punches, dies, and guides, where failure is not an option.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
