Bond:

The hybrid bond combines the advantages of both resin and metal bond — delivering the free-cutting action and fine surface finish of a resin bond with the durability and form retention of a metal bond. The result is longer wheel life, consistent performance, and reduced dressing frequency compared to standard resin bond wheels.

Compatibility:

Fits ANCA, Rollomatic, Walter, and similar CNC tool grinders with 31.75mm (1¼") spindle arbor. Please verify your machine spindle configuration before ordering.

Coolant:

Oil-based coolant required.
