HSS Combination Tapping and Drilling Bits


Complete hole drilling, tapping, deburring and countersinking in one operation with power drill saves labor and time.

Self-centering point, do not need assistant center drilling or center punching.

Taps produce internal threads in previously formed holes and can be used in machines (such as drill presses) or with hand tools.

Modified bottoming chamfer has additional length to reduce chip load, add tool life, and permit higher tapping speeds.

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.

Made from HSS with titanium coated, high hardness and rust resistance, durable and long service life.

Suitable for drilling, tapping, cutting on soft metal, aluminum plate, iron, etc.
