Helicoil Manual Combined Taps


Combined Manual Helicoil Taps are designed to self-align with the existing thread, requiring very little effort in getting the tap straight. The combined tap does not require pre-drilling of the damaged hole, as it is designed to cut the hole larger, while cutting the new thread. Very useful if you require speed and accuracy at the same time. We do however advise that when tapping into steel, to pre-drill your damaged hole to the nominal diameter needed. This just prolongs the life of your investment.
