• ★ Tap and Drill Bit Set Size --- Screw tap: thread size: 3/8-24 UNF. tapping direction: right hand. accuracy: 2B. square shank size: 6.2mm / 0.24". thread length: 21mm / 0.83". overall length: 76mm / 2.99". Drill Bit: diameter: 8.5mm / 0.335". flute Length: 75mm / 2.95". overall Length: 117mm / 4.61". point angle: 108 degree ★ Wide Applications --- Repair damaged threads or create new threads in stainless steel, aluminum alloy, cast iron, copper, iron, aluminum, and plastic. The tap is used for tapping internal threads in through holes or shallow blind holes, such as threads in nuts, threaded inserts, pipes, valves, parts, furniture. ★ Ease of Use --- The machine tap is designed with straight flutes and fast downward chip removal, suitable for tapping machines, drilling machines, CNC and milling machines. The drill bit with sharp spiral flutes can create smooth and accurate holes, and allow faster drilling speeds, export of metal chips, and improved coolant flow. ★ High-speed Steel --- The 6542 high-speed steel (hss) tap combines hardness and toughness, with excellent wear resistance and durability. M35 5% cobalt high speed steel (hss-co) drill bit provides excellent wear resistance, durability, heat resistance, and optimal chip removal. ★ Useful Tips --- Apply a suitable lubricant helps to prolong the life, reduce friction, and improve hole and thread quality. Drill a hole with the correct size drill bit before tapping. Make sure the tool is properly aligned with the workpiece and has enough clearance to remove chips. Always use the correct speed and pressure.
