Cutting tools begin with the right foundation, and that foundation is the blank. At Extramet Products, LLC, we specialize in producing precision-engineered tungsten carbide blanks that serve as the starting point for high-performance tools used across multiple industries. By combining decades of carbide expertise with advanced grinding and machining technology, we deliver consistent quality that toolmakers trust. Our ability to manufacture both standard tungsten carbide blanks and specialized tungsten carbide rotary cutting tool blanks allows us to support customers ranging from small machine shops to global OEMs.
Why Extramet Blanks Stand Out
Toolmakers know that the quality of a blank determines the reliability of the finished tool. Extramet’s blanks stand out for their superior edge stability, precision tolerances, and smooth surface finishes. We maintain tolerances as tight as ±0.0001″ through our advanced CNC cylindrical grinding and centerless grinding capabilities. Every blank is designed to minimize grinding excess, reducing finishing time and cost for our customers. Whether you need a standard rod or a complex blank for rotary tooling, our products are engineered for performance and reliability.
Types of Cutting Tool Blanks Offered
Extramet manufactures a wide range of blanks to suit different machining applications. Our catalog includes solid rods, rods with coolant holes, and helical rods for enhanced cutting efficiency. We also produce preforms and semi-finished blanks tailored to customer specifications. This versatility ensures that we can supply the right tungsten carbide blanks for drills, end mills, reamers, and other precision cutting tools. For demanding rotary machining applications, our tungsten carbide rotary cutting tool blanks provide durability and performance under the most rigorous conditions.
Material Excellence – Tungsten Carbide Grades
The strength of a blank lies in the material. Extramet offers a wide range of proprietary tungsten carbide grades engineered for wear resistance, corrosion resistance, and consistent metallurgical properties. We adjust cobalt binder percentages and grain sizes to meet specific toolmaking needs. By providing multiple grade options, we make sure that our tungsten carbide blanks and tungsten carbide rotary cutting tool blanks can be optimized for cutting speed, longevity, and performance across different materials.
Precision Manufacturing Capabilities
Extramet has invested heavily in advanced equipment to deliver the highest levels of precision. Our facility includes CNC cylindrical grinders, centerless grinders, and surface grinders capable of handling parts up to 36 inches in length. We also offer laser etching for part identification and traceability. These capabilities allow us to manufacture tungsten carbide rotary cutting tool blanks with consistent dimensional accuracy and repeatability. Toolmakers can depend on every Extramet blank to meet their specifications without compromise.
