Tap and Drill Bit Set, M4 x 0.7 Thread 150mm Length Tap 4mm Drill Diameter, Metric Extra Long Machine Screw Tap & Twist Drill Kit - (Applications: for Threading Tapping), 1-Set

Attributes:* Tap Thread Size: M4 x 0.7 (Right Hand); * Tap Accuracy: H2* Tap Square Shank Size: 3.1mm / 0.12"; * Tap Thread Length: 23mm / 0.91"; * Tap Overall Length: 150mm / 5.91"* Drill Bit Diameter: 4mm / 0.157"; * Drill Bit Flute Length: 105mm / 4.13"; * Overall Length: 160mm / 6.3"; * Angle: 108 DegreeWhat Is Included:* 1 Piece x Thread Tap, 1 Piece x Drill BitApplications & Features: (Note: In the set, the drill bit is NOT suitable for drilling holes for the tap before tapping.)--- The tap and drill bit set can repair damaged threads or create new threads in maintenance work, suitable for processing stainless steel, aluminum alloy, cast iron, copper, iron, aluminum, plastic. The thread 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.--- The 6542 high-speed steel (hss) screw tap and drill bit set combines hardness and toughness, with excellent wear resistance and durability. The thread tap with straight flute design, fast downward chip removal, and the end chamfer helps guide the tap into the hole and start the thread. The machine tap is used on tapping machines, drill presses, 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 during drilling operations, saving time and effort.Useful Tips:--- Apply a suitable lubricant helps to prolong the life, reduce friction, and improve hole and thread quality. Always 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.
