Spiral Point Tap M8x1.25

This Westward 5TWL3 is a spiral-point tap for cutting M8 metric coarse threads. It suits maintenance technicians and machinists who need to create new internal threads or clean damaged ones in through-holes. The two-flute design pushes chips ahead of the cut for smoother operation.

Thread size M8x1.25

The single specification that decides fit is the M8 diameter with 1.25 mm pitch. Match this exactly to the hole and fastener; any other pitch or diameter will produce threads that do not engage. The D5 limit and 3B class of fit are built to this size.

Plug chamfer eases starting

The plug chamfer helps the tap enter straight, reducing the risk of cross-threading in through-holes. Bright high-speed steel requires cutting fluid to prevent galling. Running dry or reversing under load often chips the flutes.

Questions about this item

How does the M8×1.25 thread size work when I am tapping a hole in a real machine?

The M8×1.25 designation means the tap cuts an 8 mm major diameter with a 1.25 mm pitch, producing a metric coarse thread that matches standard M8 bolts and nuts.

What does the plug chamfer and D5 limit mean for the threads I cut?

The plug chamfer starts the thread easily in through-holes, while the D5 limit and 3B class of fit give a tighter tolerance suitable for precision assemblies.

What physical space do I need for the 2 23/32 in overall length and 1 1/8 in thread length?

The tap measures 2 23/32 inches overall with a 1 1/8 inch thread portion, so allow that clearance plus room for the handle or holder you use.
