FIELD: process engineering.
SUBSTANCE: boring tool runs in lengthwise direction and features apex, first and second main cutting edges extending outward. Apex is located eccentrically relative to boring tool central axis that doubles as axis of rotation shifted by 0.02-0.06 mm, while second main cutting edge is located above the first one in lengthwise direction to apex by the difference in height of said cutting edges, at, at a time, features smaller radial length compared with the first one.
EFFECT: higher wear resistance.
