Description
This 1-1/4 UNC to 1/2 BSP adaptor fits drills and core drilling machines equipped with a 1-1/4” 7UNC female spindle. It converts the spindle connection to a 1/2” BSP male thread, which allows operators to run BSP-threaded core bits on rigs that would otherwise support only UNC tooling.
Because core drilling equipment often varies by thread standard depending on manufacturer and region, operators frequently encounter compatibility limitations. This adaptor addresses that challenge by enabling mixed thread use without requiring machine modification or additional tooling changes. As a result, users can work more efficiently while maintaining flexibility across different core bit inventories.
The adaptor uses durable steel construction to support professional drilling environments where strength and reliability matter. In addition, it maintains secure thread engagement during drilling. Depending on the machine configuration and application requirements, operators can use the adaptor with both handheld drilling setups and rig-mounted core drilling systems.
Overall, this 1-1/4 UNC to 1/2 BSP adaptor suits contractors and distributors who support multiple drilling standards and need a practical way to expand core bit compatibility across different machines.
