Located in the industrial heart of Amman, Jordan, Sabra Metals has built a reputation for precision and reliability as a trusted manufacturer and supplier. Our expertise shines through in our production of High Speed Steel M42 bars, a premium-grade material engineered for demanding applications. We understand that your tools are an extension of your craftsmanship, which is why we ensure every bar meets stringent quality standards, providing professionals across the region with the exceptional performance and durability needed to tackle the toughest cutting and machining challenges.
The exceptional quality of M42 steel comes from its unique composition, which includes a high cobalt content alongside significant amounts of tungsten and molybdenum. This specific alloy blend gives it a remarkable hardness, often exceeding 67 HRC after heat treatment, allowing it to maintain a sharp cutting edge even when exposed to the high temperatures generated during intense operations. This combination of superior red-hardness and excellent wear resistance is what sets M42 apart, making it a go-to choice for tasks where other steels would quickly fail.

Yes, High-Speed Steel M42 can be welded, but it requires specialized techniques like preheating, post-weld heat treatment, and using appropriate filler materials to avoid cracking and maintain its properties.
Yes, High Speed Steel M42 bars are recyclable. They can be melted and reused in manufacturing, reducing waste and conserving resources, making them an environmentally friendly material choice.
These bars are ideally suited for creating high-performance cutting tools that must perform under pressure. You will commonly find M42 steel used in drill bits, end mills, reamers, and saw blades, especially when machining tough materials like stainless steel, high-temperature alloys, and titanium. Its ability to retain a keen edge at elevated temperatures makes it indispensable in industrial settings, from automotive manufacturing to aerospace engineering, where precision, speed, and tool longevity are critical for productivity and achieving a superior finish on the final workpiece.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
