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): 3.15mmThreading length - millimeter (THL): 10mmThread diameter - millimeter (TD): 2.5mmBasic standard group (BSG): DORMER-ISOMaterial code (BMC): High Speed SteelThread diameter size (TDZ): 3Thread form (THFT): M - Metric coarseFlute count (NOF): 2Hand (Cutting direction): RightMaterial Application Priority Usage: P - Steel and cast steelAlt Part Number (Material ID): 5978325Hole Type: Through HoleCoating: Steam TemperedPackage Quantity: 1Country of origin: BrazilSellable Unit Weight: 6Brand: DormerPackage Dimensions: 10 x 82 x 10mm
