Our ER M Spanner Collets are precision-engineered components designed for use with CNC milling machines and various tool holding applications. These collets feature a specialized open spanner design that provides secure clamping for cutting tools, tap holders, and MT adapters.

Manufactured from high-quality stainless steel, these collets undergo cryogenic treatment for enhanced durability and performance. The black surface finish not only provides corrosion resistance but also ensures easy identification in industrial settings.

The collets are available in five standard sizes to accommodate various tool diameters: 8mm, 11.5mm, 15mm, 19.5mm, and 25mm. Each size is designed with precise dimensions to ensure optimal grip and concentricity during machining operations.

These spanner collets feature a manual working mode with unfolded design for easy operation. The metallic handle provides excellent grip while maintaining the tool's balance during use. The common size and ordinary feature make them suitable for standard milling applications.

With their metric standard design, these collets are compatible with most international tooling systems. The clamping nut usage ensures secure fastening of cutting tools, reducing vibration and improving machining accuracy.
