Product Information

Integral adjusting screws may be arranged to work axially, where the movement of the adjusting screw into a threaded hole in the die forces the slit section of the die open, or tangentially where a screw threaded in to one side of the slit bears against the opposite side of the slit. Proper lubrication is essential because of the frictional forces involved, therefore a lubricating oil is used instead of cutting oil. Intermediate tap, second tap, [3] or plug tap The tap illustrated in the middle of the image has tapered cutting edges, which assist in aligning and starting the tap into an untapped hole. Length compensation: built in length compensation takes care of small push or pull to the spindle or feed difference.

I kept my eye on the end of the tap where it was held in the handle, and concentrated on that not moving sideways. Safety clutch: The built in safety mechanism operates as soon as the set torque limit is attained to save the tap from breakage.With the introduction of more advanced milling practice in the 1860s and 1870s, tasks such as cutting a tap's flutes with a hand file became a thing of the past.

To cut it off so it can drop out of the way, reverse the tap direction for a quarter or even a half turn. Re-Threaders are Ideal for: Quickly cleans and re-threads fixing holes in socket-switch or conduit-boxes which can often be blocked by cement or plaster and have malformed threads. The most common type of power driven tap is the "spiral point" plug tap, also referred to as a "gun" tap, whose cutting edges are angularly displaced relative to the tap centerline. Double-lead taps and insert taps need different speeds and feeds, and different starting hole diameters than other taps.
