First run with my power tapping head attachment
The first run with my HBM Machine power tapping head attachment.
(HBM Machines MC-2 M3-M12 tapping head)
A Arboga GM2508 drill press runs the tapping head at 105 rpm through 8mm cold rolled steel. A selection of Dormer machine taps with spiral flutes were used.
I´m very pleased with the result.
