SF-3M Virgin Grade Carbide – Silver Brazed Preform for Custom Grinding

The SF-3M is a semi-finished burr preform made from virgin grade tungsten carbide. Virgin carbide means it is produced from new, unrecycled raw materials, offering consistent quality and reliable performance for precision grinding applications. The carbide tip is securely joined to the steel shank using silver brazing, providing a strong and durable bond that withstands the stresses of custom tooth grinding and final use.

It is ideal for tool manufacturers, professional resharpening shops, or specialized users who require high-quality blanks for creating custom rotary burrs. The standard 6mm shank is ready for final processing.
