Drilling, Tapping and Deburring in one operation with 1/4''-Hexagon Drive

•  Combined Tap Bit with 1/4" Hexagon Drive 30° Spiral Flute HSS-G - UNC 5/16 x 18

• Combined-Bits have been designed for drilling, tapping and deburring in one operation using battery-powered screwdriver drills and electric hand drills with right-hand and left-hand rotation, but they are also suitable for thread cutting in a stationary drilling machine.

• The Combined Bit is suitable for universal use in materials of medium mechanical strength, non ferrous metals and thermoplastics (up to 600 N/mm² tensile strength).

• The tool can produce through threads up to a maximum threaded depth of 1 x D.

• They are especially useful for assembly work and small batch production.

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