FIELD: process engineering.
SUBSTANCE: invention relates to tools for making profile cuts in blast holes. Proposed tool comprises body with the element for coupling with drill rod. Tool opposite side is provided with jig plate for feeding the tool in blast hole, inner tool and blast hole bents and shaped hard alloy inserts fitted in body grooves. Body grooves accommodate flexible elements to contact with hard alloy insert front end and with groove walls. Hard alloy inserts are fitted for lengthwise displacement in grooves, insert thrust surface being inclined towards the master plate.
EFFECT: higher reliability.
