Extension for BORMAX drill bits
Extension for BORMAX drill bits
If 57 mm cutting length of the Bormax is not enough, you can use these extensions for deeper holes. They are suitable too for all other drill bits with a shaft of 8 or 10 or 13 mm, if it is paid attention to the minimum cutting diameter of the drill bit. You need a 2.5 mm hexagonal bit to fit the extension. Please note there are different shaft sizes of "Bormax" and "Bormax 3 carbide tipped" forstner bits! All measurements in mm!
