A material specific cut tap for blind hole / bottoming (Enorm AL) and through hole / plug (Rekord B-AL) designs. In the machining of long-chipping aluminum, it is absolutely necessary to provide chip transport in an axial direction. In addition to the large rake angle, these tools are made with a reduced number of flutes so that there is even more room for the chips. This helps to avoid clogging of the flutes in cut threading operations.

Spiral Point Taps is also known as ‘gun nose’ or ‘bull nose’ or chipdriver. These taps are dimensionally the same as a hand tap, second lead, but have the cutting face ground back relative to the axis of the tap, for the lead portion. This gives the flute a better cutting action, requiring less power, and pushes the cut material forward, allowing free flow of coolant along the flutes to the cutting edge. The flutes are not ground as deeply as for hand taps, giving the tap greater strength. It can therefore be run at higher speeds. Spiral point taps are ideal for machine tapping of through holes, or blind holes where there is enough clearance beyond the threaded portion to accommodate the swarf. Advantages Thread Chamfer is of 4.5 threads & cutting load is distributed Shallow flute depth, hence stronger tap Chip clogging is eliminated as the tap pushes the chip forward and thus enhancing tool life.
