FIELD: process engineering.
SUBSTANCE: proposed tool comprises holder and head with rear and front ends to be jointed to accommodate the plate supporting replaceable cutting plate. Front end of said holder comprises internal of external element for connection of said holder with threaded bore for screw and multiple support surfaces of the wall adjoining the flat thrust surface. Rear end of said holder comprises internal of external element for connection of said holder with through bore for screw and multiple adjacent support surfaces of the wall adjoining the flat thrust surface. Note here that thrust surface stay in contact with thrust surface while at least three of multiple thrust surfaces stay in contact with at least three of multiple support surfaces. Note here that fastening screw extends through the head through bore to interact with holder threaded bore. Note also that at least three of multiple thrust surfaces are not located in one plane and are located at acute third angle to main plane including holder lengthwise axis if seen in direction of thrust surface.
EFFECT: higher precision and reliability.
