Pavement Breaker And Rock Drill Attachment - PB-RD-VDEX fits all pneumatic, electric and hand held hydraulic pavement breakers and rock drills regardless of weight class and shank size. - Our patented friction mag design attaches to the drill steel rather than the tool. - The friction mag device rotates when used with rock drills. - The friction mag device allows the PB-RD-VDEX to be easily installed over the shank and collar end of all pavement breaker and rock drill steel. - When using rock drill bits over 1-7/8" diameter it is recommended that you use the VDEX-NZL-4IN bristle foot. NOTE: For job sites requiring water dust suppression use the VDEX WATER PLUG.
