Diamax Core Drill Bit Adapter – 1/2 in. Chuck to 5/8-11 Male Thread
Diamax Core Drill Bit Adapter – 1/2 in. Chuck to 5/8-11 Male Thread
The Diamax Core Drill Bit Adapter is a core drill bit adapter, 1/2 in. chuck to 5/8 in.-11 male thread, for running a threaded core bit in a drill chuck.
It converts 1/2 in. chuck to 5/8 in.-11 male thread, so a core bit built for a grinder spindle will run in a drill. Note the chuck size: Diamax publishes 1/2 in., and some listings for this part show 3/8 in., which is wrong.
Key Features
- 1/2 in. chuck to 5/8 in.-11 male thread
- Maximum 10,000 RPM
- Lets a threaded core bit run in a drill chuck
Not Recommended For
It is an adapter, not a bit — it carries no diamond. Pair it with a core bit such as the Diamax Cyclone Dry Wet Core Bit – 1 in., for Granite, Quartz & Porcelain.
Who Is This For?
Installers drilling with a hand drill who own threaded core bits built for a grinder.
