Aopin M8 x 0.75 Taper Hand Tap HSS Metric Female Thread High Speed Steel Hand/Machine Use Straight Flute Screw Tap, for Used to Make New Threads, Re-Thread Damaged and Jammed Threads 1 Pcs

• Taper Tap Size: M8, Pitch: 0.75mm, Material: High Speed Steel (HSS).
• Our hand tap is suitable for through-holes and can be used with tapping wrenches to tap new female threads, re-thread damaged or jammed threads. Fine thread design.
• Machine taps material: The taps is made of high hardness high speed steel. It is suitable for tapping on the machine tool and can also be tapped by hand. Good red hardness and wear resistance. Cutter bit is not easy to break. The tapping speed is fast, the high precision and good chip removal. Taper Style: Starts the thread square with the workpiece.
• Features: Three rows of straight grooves, good chip removal effect, sharp teeth without burrs and high strength, end is square handle style, convenient for firm clamping to tool, round drill bits design. Small hole at bottom facilitates the cooling liquid to enter to achieve the purpose of cooling taper tap. Straight flute tools allow chips to collect in the flutes as they cut. Designed for hand cutting plastic, copper, brass, aluminum, sheet metal and other materials applications.
• Easy to use: When tapping, every 1/2 or 1 turn of the twister should be turned, it should be reversed about 1/2 turn, so that the chips are easy to be discharged after breakingand. Thereby avoiding the stuck of taper taps due to the blockage of cutting edge. During this process, it is advisable to add coolant at the same time, and do not touch the cutting edge with your hands directly to avoid scratches.

Why choose our hand taper taps? Use high speed steel material with high hardness, good red hardness and wear resistance. It is one of the best materials for making taps. The chip flute is designed to prevent the tap from overheating, which causes the drill bit to break easily when the internal thread is processed. The part is a square shank, which is convenient for machine tools or fixtures to clamp firmly. Our taps are the best choice for processing through-hole internal threads. How to distinguish between Taper Taps and Bottom Taps? Taper Taps: Start tapping threads square with workpieces. Mainly used for female thread processing of through-holes Bottom Taps: Generate threads to the bottom of holes. Mainly used for female thread processing of blind holes. Note that when machining blind holes, the reserved hole depth is 1.5 Pitch more than required thread depth. How to use reasonably? (1) When tapping, insert the taps head first to make the center line of the tap consistent with the center line of the drill hole. (2) Rotate evenly with both hands and apply a little pressure to make the screw tap enter the hole. There is no need to apply pressure afterwards. (3) Each time the tap is turned, it is reversed by about 45° to cut off the chips, so as to avoid blockage. (4) Do not increase the rotating force if the tap is difficult to rotate, otherwise the tap will break.
