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): 6.3mmThreading length - millimeter (THL): 17mmThread diameter - millimeter (TD): 5.1mmBasic standard group (BSG): DORMER DINMaterial code (BMC): High Speed SteelThread diameter size (TDZ): 1/4Thread form (THFT): UNC - Unified CoarseFlute count (NOF): 2Hand (Cutting direction): RightHole Type: Through HoleCoating: Steam TemperedMaterial Application Priority Usage: P - Steel and cast steelPackage Quantity: 1Country of origin: BrazilSellable Unit Weight: 20gAlt Part Number (Material ID): 5978353Brand: DormerPackage Dimensions: 17 x 89 x 14mm
