Summary:The utility model discloses an RFC draw bar with sand cleaning holes. The RFC draw bar comprises a hook tail end part spherical surface and a bar body, wherein a hook tail hole is formed in the hook tail end part spherical surface; the sand cleaning holes are uniformly distributed in two sides of the lower part of the bar body by taking the central line of the bar body in a longitudinal direction as an axis; the central distance of every two sand cleaning holes is 1/2 of the length of the bar body. compared with an existing RFC draw bar, the RFC draw bar with the sand cleaning holes has the advantages that two sand cleaning holes are additionally formed in the lower part of the bar body on the premise of not changing original process holes, and the turning efficiency of the draw bar can be improved under the action of the sand cleaning holes; in the meantime, sand can be cleaned more thoroughly to provide guarantee for subsequent machining of the draw bar.
