Description

The 5/16 UNC spiral flute tap and drill set provides reliable threading for applications requiring this popular intermediate size. Producing a 6.6mm thread diameter with 21mm threading length, this combination tool serves well in equipment assembly, automotive applications and general metalworking where five-sixteenth inch UNC threads are needed. The integrated drill-and-tap design saves considerable time on site by eliminating tool changes. Constructed from high-speed steel with steam tempering, this tool delivers consistent cutting performance throughout its working life. The 8mm connection diameter fits securely in standard power drill chucks, whilst the two-flute spiral pattern removes swarf efficiently during operation. Both professional tradespeople and home workshop users will appreciate the convenience of creating accurate threads without switching to separate tapping equipment. Features and Benefits: • Single-pass threading dramatically reduces job completion time • Steam-tempered coating retains cutting fluid for superior finish • Two-flute spiral configuration ensures effective chip removal • Cylindrical shank with square drive for power tool compatibility • Right-hand cutting direction suits standard threading requirements • Designed for through-hole work in steel and cast steel Specifications: Diameter: 5/16 UNC Type: Sprial Flute Shank: Cylindrical shank with Square Connection diameter - millimeter (DCON MS): 8mm Threading length - millimeter (THL): 21mm Thread diameter - millimeter (TD): 6.6mm Basic standard group (BSG): DORMER DIN Material code (BMC): High Speed Steel Thread diameter size (TDZ): 5/16 Thread form (THFT): UNC - Unified Coarse Flute count (NOF): 2 Hand (Cutting direction): Right Hole Type: Through Hole Coating: Steam Tempered Material Application Priority Usage: P - Steel and cast steel Package Quantity: 1 Country of origin: Brazil Sellable Unit Weight: 33.6g Alt Part Number (Material ID): 5978365 Brand: Dormer Package Dimensions: 20.5 x 118 x 17mm
