They are high diamond concentration provide aggressive cutting action, excellent for drilling marble and granite with high performance and durable life. They are designed with 5/8"-11 or M14 or M10 female thread and attached with a composite elasticity gasket so they can be mounted to any angle grinder and work on stone with vibration-proof.

We offer many adapters. Adapter unit screws into a Drill Bit to affect operative compatibility between different machines.
