Volkel M3 x 0.5 HSS Combined Drill & Tap
The Combined Tap enables the user to produce the tapping drill hole and
the through thread in one operation without any tool changing. The tool
incorporates a twist drill before the threadtapping part. It is possible
with this tool to produce through threads up to a maximum threaded
depth of 2 x D.
The Combined Tap is suitable for universal use in materials of medium mechanical strength:
non-alloyed and alloyed steel sorts up to 600 N/mm2, malleable cast
iron, nodulized graphite cast iron, copper, brass, aluminium,
aluminium-magnesium and zinc alloys, red bronze, electron metal,
pressure-cast zinc.
It is sensible to use this tool on machines possesing an RPM switchover
facility for drilling and tapping. The feed rate must be adapted to the
particular operation required - drilling or tapping.
Tapping chucks with pressure compensation may not be used.
