HSS Cobalt Screw Thread Tap HSSE Spiral Pointed Plug Gun Tap Threading Spiral Point Tap M8*1.25

* Long service life: Compared with ordinary straight fluted taps, the life span of spiral fluted taps can be increased by
30%~50%, and some up to 2 times. This is because the chips are quickly discharged along with the spiral flute tap during the tapping process and will not be blocked in the groove and will not be discharged. There are few chipping and breaking
phenomena, which improve the service life.
* High efficiency and low cost: For tapping metal threads in difficult-to-machine materials, such as tapping blind hole and
cutting threads in stainless steel, structural alloy steel, and various non-ferrous metals, with spiral groove taps, only need
to use one tap for processing, and does not need to use grouped taps for processing. When tapping internal thread, there is no need to repeatedly advance and retract the tap to remove chips, which improves the tapping efficiency and saves the high-speed steel materials used to manufacture the taps, and reduce the cost.
* Adequate cooling and lubrication conditions: Because metal chips can be automatically discharged along with the spiral flute, it is not easy to block, the cooling and lubricating needs during cutting are improved, and the heat generation of the cutting part of the tap is reduced. This also enhances the durability of the tap.
* Smooth cutting, easy to buckle, low roughness
* Small torque: Due to the smooth chip removal, the chips are not blocked in the narrow chip flute, and the existence of the helix angle increases the actual work
* Angle, so the torque is small, generally about 30% smaller than the straight flute tap.
