Hex Tap Type S Threading Bit, 1/4" hexagon drive Form D HSS-G

Threading-Bits have been designed for thread cutting using battery-powered screwdriver drills and electric hand drills with right-hand and left-hand rotation.

But they are also suitable for thread cutting by hand or in a stationary drilling machine.

Your battery-powered screwdriver drill should have a minimum power of 7.5 Volts.

Take care that the tool and the axis of the hole are exactly aligned and use a suitable cutting oil.
