A point tap is a type of tap that is a threading tool and is specialized for threading through holes. (Also known as a gun tap.) The tip of the tap is twisted and sharp.
Since the tip is twisted and sharply shaped, and the chips are produced in a forward direction, the chips do not block the hole, and trouble caused by chips is unlikely to occur during continuous machining on a machine, thus enabling stable tapping in mass production.
Conversely, a point tap is not suitable for tapping when the bottom of the hole is present.
Point taps are basically used in machining, so they are used for large-volume through-holes and continuous machining of mass-produced products.
Since the load during cutting is smaller than that of other taps, point taps has the features of less trouble such as tap breakage and quicker processing, so point taps are used in most situations for mass-produced products where you want to increase productivity and produce as many products as possible in the same time.
Also, the advantage of point taps is that they do not easily become dirty after processing, making it easy to clean the jig and the product.
Unlike hand taps and spiral taps, the shape of the tip of a point taps is grooved so that chips fall in the direction of the blade. The structure of the tap is such that chips slide down along that groove.
On the other hand, because the biting portion at the tip is cut deeper, the tap cannot be cut to the bottom edge of a hole with a hole bottom, and the chips will block the hole due to forward discharge, making it unsuitable for machining a stop hole.
In the case of spiral taps, the groove of the blade is spiral-shaped and chips are discharged along the groove in the opposite direction of the tap, so chips do not interfere with machining.
There are two types of tap materials: high-speed tool steel (HSS) and cemented carbide. HSS is tough and does not break easily, while cemented carbide is resistant to wear and does not wear easily even after continuous machining. Since the compatibility differs depending on the material to be processed, it is necessary to select a tap suitable for each material when processing.
