DUSS Diamond Core Drill Bit:52mm x 450mm x 1 1/4"UNC (Internal)

This DUSS diamond core drill bit is engineered for precision boring applications, featuring a 52mm nominal diameter and a 1 1/4" UNC internal thread connection. Constructed with diamond impregnated cutting edges, it is designed to efficiently remove hard materials while maintaining a clean bore. The internal thread design allows for direct attachment to standard drilling equipment without requiring a separate bushing or adapter, simplifying setup and improving rigidity. It is rated for a nominal length of 1, which indicates the specific penetration depth capability for this configuration. Buyers select this bit for its compatibility with common 1 1/4" UNC drilling systems, ensuring broad tooling availability. When choosing a size, match the 52mm diameter to the required hole dimension and verify the 1 1/4" UNC thread matches your machine head.
