YOUR APPLICATION COMES FIRST
A clear specification starts a better technical conversation. Here is how to prepare your enquiry.
Tell us the workpiece material, machining process and tool or die design.
Share your preferred series, dimensions, crystal orientation and required geometry.
Include quantity, destination and target date so our team can discuss availability.
Start with SR or SN for precision finishing, SC for shaped tools and wear parts, STN/STT for dressing tools, and SD for wire-drawing die cores. Confirm suitability for your process with our team.
The SC series includes cuboids, cylinders and triangular prisms cut from in-house rough. Send a drawing to discuss non-standard geometries and dimensions.
Confirm dimensions, orientation, tolerances, quantity and availability. Our catalogue gives reference specifications; the final selection depends on your application.
