Tap wrenches

There are two main types of tap wrenches: bar type (double-end) and T-handle. A tap wrench is used by hand to turn taps or other small tools such as screw extractors. The T-handle tap wrench uses a chuck to secure the tool. The chuck forms a clamp around the object to hold it in place. It's useful in confined spaces or where extra reach is needed because of its upright body. There are two main types of tap wrench: bar type (double-end) and T-handle.

T-handle design

A tap wrench is used by hand to turn taps or other small tools such as screw extractors. The T-handle tap wrench uses a chuck to secure the tool by forming a clamp around the object to hold it in place.

Because of it’s lengthy design, it’s useful in confined spaces or where extra reach is needed.

T-handle tap wrenches have a chuck width of: 1.5 - 3 mm 2 - 5 mm 2.5 - 5 mm 4 - 6.8 mm 4.6 - 8 mm 8 - 12 mm T-handle tap wrenches have a chuck width of:

  • 1.5 – 3mm
  • 2 – 5mm
  • 2.5 – 5mm
  • 4 – 6.8mm
  • 4.6 – 8mm
  • 8 – 12mm
A bar type (double-end) tap wrench has one threaded handle which is attached to one of the clamps. The clamp is opened by unscrewing the threaded handle. The tool is then inserted, for example the picture on the left, with the threaded handle, then screwed to tighten against the tool to secure it.

Bar-type design

A bar type (double-end) tap wrench has a threaded handle which is attached to one of the clamps and is used to open and close it.

The tool is inserted and secured against the tool, using the handle.

Bar type tap wrenches have a clamp width of: 2.50 - 12 mm 4.25 - 14.40 mm 4.25 - 17.70 mm 6.80 - 23.25 mm M4 - M8 - 4 - 8 mm thread M4 - M14 - 4 - 14 mm thread M7 - M27 - 7 - 27 mm thread. Bar type tap wrenches have a clamp width of:

  • 2.50 – 12mm
  • 4.25 – 14.4mm
  • 4.25 – 17.7mm
  • 6.80 – 23.2mm
  • M4 – M8 – 4 – 8mm thread
  • M4 – M14 – 4 – 14mm thread
  • M7 – M27 – 7 – 27mm thread

Drills

A drill is a tool that holds a cutting or driving tool attachment. A screw extractor is gripped by a chuck and rotated while pressed against the target material. The suitable drill chuck size for a screw extractor would be a 3/8 inch variable speed drill. This means its maximum capacity is 10 mm as the screw extractors will not be any bigger than this size. Some screw extractors can be used in drills. The extractor is held securely in the drill’s chuck and rotated whilst being pressed against the target material.

Screw extractors have an end diameter of 10mm (3/8” approx.), so will require a chuck with the same capacity in order for them to be used.

Mole grip pliers

Mole grip are pliers that can let the user lock them into position. A bolt is placed on one side of the handle to adjust the width of the jaws and the other handle acts as a lever to unlock pliers. Mole grip pliers are hand tools that can be locked into position in order to turn the extractor or remover manually.
