For 85 ° to 45 °.
The utility model is further arranged to, and one end of the mechanical clamped cutting blade point of a knife towards knife bar axial direction tool apron is overhanging
The blade of 0.5mm to 1mm is right boring blade.
In said structure, right boring blade can use YW series hard alloys, and to ensure service life, heavy boring blade can use YG
Series hard alloy, enables it to bear larger impact and vibrations in half right boring of heavy boring, avoids the occurrence of spring sword.
The beneficial effects of the utility model：Right boring directly can be carried out to endoporus after half right boring of heavy boring, without withdrawing to car
Bed knife rest, which carries out rotation, which replaces lathe tool, can save substantial amounts of process time and processing cost.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
With reference to figure 1 and Fig. 2, a kind of coarse-fine lathe tool of endoporus twolip as shown in Figures 1 and 2, including knife bar 10, the knife bar
10 one end are equipped with tool apron 20, and the tool apron 20 is equipped with two and is laid in 180 degree rotation centered on 10 central axis of knife bar
