Welcome to Tariku Metals, your trusted partner in Addis Ababa for industrial-grade materials that power Ethiopia’s growing manufacturing sector. We specialize in supplying High Speed Steel T15 bars, a premium tool steel renowned for its incredible durability and cutting performance. Sourced from leading producers, our T15 stock is delivered with the reliability and expertise your business depends on, helping you tackle the most demanding machining and tooling challenges with complete confidence, right here in the heart of the nation’s industry.
The exceptional quality of High Speed Steel T15 stems from its unique composition, which is rich in tungsten, vanadium, and cobalt. This specific blend gives the steel its signature ability to retain a sharp cutting edge even when exposed to the intense heat generated during high-speed operations. The result is a material with outstanding wear resistance, impressive hardness, and formidable strength, making it a truly superior choice where other tool steels would quickly fail under pressure.

High-Speed Steel T15 bars are sized by their diameter and length, typically ranging from small diameters for precision tools to larger sizes for heavy-duty applications, tailored to customer specifications.
Yes, High-Speed Steel T15 bars are recyclable. They can be melted down and repurposed into new products, making them an environmentally friendly option for sustainable manufacturing and reducing material waste.
High-speed Steel T15 bars should be stored in a dry, cool environment, away from moisture and extreme temperatures. They should be kept on racks or pallets to prevent rust and damage.
In practical terms, T15 bars are the backbone of high-performance cutting tools used across various industries. They are expertly forged into milling cutters, drill bits, broaches, and gear shapers that excel in machining tough materials like stainless steel and high-temperature alloys. Whether in an automotive plant, an aerospace component manufacturer, or a local tool and die shop, T15 tools are valued for their long service life and consistent results, directly contributing to greater productivity and lower operational costs.
