Located in the heart of Kinshasa, Sadiki Metals is a trusted name for industrial strength and precision. We take pride in producing and supplying top-tier High Speed Steel T15 bars, engineered to meet the rigorous demands of the modern manufacturing sector. Our commitment is to provide local industries with a reliable source of high-performance tooling materials, empowering businesses across Congo with the durable, cutting-edge components they need to excel in their operations and drive progress from the ground up.
The exceptional quality of our T15 bars comes from a sophisticated composition rich in tungsten, vanadium, and cobalt. This specific blend gives the steel its remarkable ability to retain hardness and cutting sharpness even when exposed to the intense heat generated during high-speed machining. The result is a bar with outstanding wear resistance and toughness, capable of performing under significant pressure and maintaining its integrity through the most challenging cutting, drilling, and shaping tasks.

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.
Because of their superior heat resistance and durability, our T15 bars are the material of choice for creating high-performance cutting tools. They are expertly fashioned into drill bits, end mills, broaches, and lathe tools that excel in machining tough materials like hardened steel, titanium, and high-temperature alloys. This makes them indispensable in demanding industries such as aerospace engineering, heavy-duty manufacturing, and precision tool and die shops where failure is not an option and performance is critical.






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