Feature(may vary by option.)
●HIGH QUALITY MATERIAL--High speed steel wire taps have high hardness and toughness, abrasion resistance and durability. In addition, for uncoated taps, only the basic base material without additional coatings (NOTE: if you properly add coolant (such as water) to extend the service life of the tap.)
●Widely used----There are 2 taps in total to facilitate alignment of tap and tapping holes, allowing the taps and holes to tapping vertically and smoothly. It also has a smoothing effect (removing burrs) of threads and can be used for re-threading new threads damaged or clogged threads. Suitable for most metal, steel, copper, zinc, alloy steel, polished steel, A3 steel, stainless steel etc. Wide Application
●Efficient and Convenient----Standard metric screw design, transparent, clean,quick shaving, efficient tapping, exquisite and durable miniature metric taps are mainly used for processing clocks, low-hardness wood and soft metal holes. Mainly used by hand, most materials are tapped in the state of the penetration hole, light and small, saving time and effort, very suitable for putting in tool bag
●Main Features----Tapered at the front end of the tap, smooth surface (very shallow) and no threads for easy "alignment" of tap and tapping holes, tap and smooth tapping holes. Second Cone Role: In addition to the ability to reach the standard, the machining headcone also serves as a buffing (deburring). Screw with "stop holes" can be tapped to the end
●Tip----The workpiece you are working must be clamped correctly. As a general rule, the sides of the workpiece that needs to be tapped should be placed horizontally or vertically. This makes it easy to judge and maintain the tapping direction vertically to the works thread seat during tapping

When you start tapping, place the tap as far as possible, one hand press the axis direction of the tap, and the other hand slowly rotate the hinge. When the tap turns 1-2, please make sure the tap is vertical from the front or side to the bottom of the work thread. Use the square to modify if necessary. In general, the direction of the tap is basically determined after tapping a 3-4 turn thread. If the tapping is correct, screw the tap, fix it with 2 taps, then tap the thread with the head tap. Insert all cutting parts in the tap eliminates the need to apply axial force when entering the work, and can be screwed naturally with the thread. When tapping the thread, do not overscrew the screw tap every time you rotate the hinge screw. Normally it is suitable to screw in 1/2-1 turn each time, and the bottom of the M5 do not screw over 1/2 turn at a time. When tapping thin screws or high precision screws, you need to decrease the feed speed right every time. The speed of striking cast iron can be done properly and faster than the speed of hitting the steel. After each screw, turn 1/2 of the stroke backward. If you tap a deeper thread, the rotational stroke will be larger and need to be screwed back and forth several times. This will break the shavings, making it easier to remove shavings, less adhesion to the edge of the blade and maintain a sharp edge. At the same time, the cutting fluid goes into the cutting area smoothly, and can be used as lubrication in cold conditions.
