Combination of a core-hole drill and tap to produce a thread in one pass. This significantly reduces the time needed to produce the thread on site with the use of a hand-held power tool. There is no need for a tap wrench or tool change. Steam tempered surface acts to retain the lubricant and provide smoother cutting.SpecificationsShank: Cylindrical shank with SquareConnection diameter - millimeter (DCON MS): 4mmThreading length - millimeter (THL): 12mmThread diameter - millimeter (TD): 3.3mmBasic standard group (BSG): DORMER-ISOMaterial code (BMC): High Speed SteelThread diameter size (TDZ): 4Thread form (THFT): M - Metric coarseFlute count (NOF): 2Hand (Cutting direction): RightMaterial Application Priority Usage: P - Steel and cast steelAlt Part Number (Material ID): 5978330Hole Type: Through HoleCoating: Steam TemperedPackage Quantity: 1Country of origin: BrazilSellable Unit Weight: 8Brand: DormerPackage Dimensions: 13.63 x 79.09 x 13.12mm
