SUBSTANCE: invention relates to devices designed for tamping ballast under ties of rails. Proposed tamping tool blade has hard alloy member of U-shaped form secured in lower part of tool to enclose front, lower and rear surfaces. Thickness of member from side of front surface exceeds thickness of member from side of rear surface. Thickness of member from side of lower surface exceeds thickness of member from side of front surface. Said hard alloy member is made sectional. Part of front, lower part and part of rear surfaces are provided with monolithic hard-alloy member, and on the rest of sections of front and rear surfaces hard-alloy members are secured discretely. Monolithic hard-alloy member and discretely fitted hard-alloy members are made of materials differing in physical and mechanical properties.

EFFECT: increased service life of tamping tool blade of tie-tamping machine.
