FIELD: process engineering.
SUBSTANCE: proposed tool has shank, head with recess with radial side surface with multiple fine-tooth joints, cutting plate with front surface formed by first-phase polycrystalline diamond provided with, at least, one cutting edge, and rear surface formed by second-phase base. Note here that cutting plate is fixed on radial side surface by clamping screw while cutting plate rear surface has multiple fine-tooth joints to be engaged with those on recess radial side surface by said clamping screw. It has also adjusting element made up of adjusting wedge adjoining cutting plate inner radial surface. Aforesaid adjusting element may displace in hole extending along chord driven by adjusting screw for radial adjustment of plate cutting edge height.
EFFECT: higher cutting accuracy.
