Thread Cutting Tool for 1/4"-20 UNC

The Westward 2LXG4 straight-flute hand tap cuts internal threads in a 1/4"-20 UNC size using three flutes and a plug chamfer. It is made from carbon steel with a bright uncoated finish and measures 2 1/2 in overall with a 1 in thread length. Suitable for general-purpose threading in maintenance or light fabrication work.

Starting Threads in Through or Blind Holes

The plug chamfer provides a moderate lead that helps the tap start straight in both through and blind holes. Apply steady pressure with a tap wrench and use cutting fluid to reduce friction. Misalignment or running dry can damage the flutes or produce oversized threads, so keep the tap perpendicular to the workpiece.

Behaviour During Extended Threading

Carbon steel holds its edge for short production runs but wears faster than high-speed steel under sustained load. Heat builds up during continuous cutting, so pause regularly to clear chips and reapply lubricant. The tool is not designed for high-volume CNC work or hard materials where rapid wear would occur.

Questions about this item

How can I verify the Westward 2LXG4 tap is cutting the correct 1/4"-20 UNC threads after setup?

Run the tap through the hole and check that a matching 1/4"-20 UNC bolt threads in smoothly for the full 1 in thread length without binding.

What comes in the box with the Westward 2LXG4 straight flute hand tap and what must be purchased separately?

The box contains the single carbon steel tap with bright finish; a tap wrench, cutting fluid and drill bit for the 1/4"-20 UNC size are sold separately.

When should I choose the Westward 2LXG4 plug-style tap over other tap styles for a 1/4"-20 UNC job?

Choose this plug tap when you need a 3-flute straight-flute tool to start threads in a through-hole or blind-hole with enough clearance for the 1 in thread length.
