Twincoil
TwinCoil inserts are two inserts, one inside the other, for the repair and/or recovery of stripped or off-centre tapped holes.
The ‘outer’ TwinCoil is always Free Running and the ‘inner’ can be either Free Running or Screw Locking.
Lengths are from 1.5D upwards, 1D inserts due to the shorter inner insert are not recommended. TwinCoil Kits come complete
with tap, Outer Inserting Tool and both Inner and Outer inserts. The Inner Inserting Tool is not included as it is a standard tool.
