About our Wire Thread Repair - Machine Taps
We are proud to supply our range of German manufactured HSS wire thread repair Insert machine taps. These high quality and durable taps, are ideal for general engineers, jobbing shops and production facilities when using thread repair inserts to resurrect a large volume of damaged holes more accurately and quickly than with wire thread hand taps. Unlike a standard hand tap a wire thread insert tap is a larger diameter than the damaged hole. Once the pilot hole (see drill size above) has been drilled and then tapped with this insert, the thread repair insert can be installed returning the damaged hole to the original size.
Hand taps are also available from our Thread Repair section if repairing smaller volumes of holes.
