FIELD: construction.
SUBSTANCE: invention relates to cutting materials and can be used for drilling holes. Cushioning sheet for drilling includes a substrate made from a metal foil and a layer containing a resin composition formed on at least one substrate surface. Resin composition contains resin and from 70 to 130 weight parts of molybdenum disulphide in relation to 100 weight parts of the resin. Layer containing the resin composition has a thickness varying from 0.02 to 0.3 mm.
EFFECT: provided are higher accuracy of positioning during drilling holes due to better centering of the drill bit, reduced wear of the drill.
