Device for grooving flow holes and threaded grooves has flow hole grooving member mounted coaxial behind threaded grooving member on single tool with adjustable drive speed
The device has a flow hole grooving member (2) with tip (3) and conical grooving part (4) mounted coaxial behind a threaded grooving member (8) on a single tool (1). The single tool is fitted on a drive which for grooving flow holes allows a slower advance of the tool than for providing threaded grooves.
