SF-5M F12.725 Virgin Tungsten Carbide Preform with 12.7mm Cut Diameter and Silver Brazed for Burr Production

SF-5M F12.725 Virgin Carbide Preform – Silver Brazed, Semi-Finished for Burr Production

The SF-5M F12.725 is a semi-finished carbide preform built for those who value both quality and flexibility in burr manufacturing. It starts with virgin-grade tungsten carbide—100% fresh material with no recycled content—ensuring consistent density, hardness, and machinability across every piece.

The silver brazing process used to join the carbide tip to the steel shank creates a bond that is both thermally resistant and mechanically robust. This means the preform holds up reliably during subsequent grinding operations and throughout the finished tool's service life.

Shaped to the SF series flame profile, this blank eliminates the need for rough forming, letting you go straight to fine-tuning the cutting geometry, tooth configuration, or surface treatment. Whether your focus is on weld removal, edge blending, or general material shaping, this preform gives you a solid foundation with room to customize.

Caburtech offers a wide selection of carbide burr shapes in Single and Double Cut styles, including Cylinder, Round nose cylinder, Ball, Oval, Tree, Flame, Cone, Countersink and Inverted Cone. Each shape is designed for grinding, deburring, chamfering, and finishing on steels under 60 HRC, stainless steels, cast iron and etc.
