Straight Flute Tap for UNC Threads
Westward 2LXK3 is a straight flute hand tap designed to cut 1/4"-20 UNC threads in a single pass. It suits machinists and maintenance crews who need a reliable tool for through-hole or blind-hole work in steel and similar materials.
Bottoming Chamfer Determines Hole Depth
The bottoming chamfer leaves only one to two threads uncut at the bottom of a blind hole, so the tap reaches full thread depth where a taper or plug chamfer would stop short. Choose this tap only when the hole must be threaded as close to the base as possible.
Carbon Steel Holds Edge in Repetitive Use
Uncoated carbon steel retains hardness during extended tapping cycles, resisting dulling better than high-speed steel in short runs but requiring cutting fluid to manage heat. Expect consistent thread quality across multiple holes before resharpening is needed.

Questions about this item
What does the 1/4"-20 UNC size mean for the threads I will cut?
It cuts a quarter-inch diameter thread with twenty threads per inch in the Unified National Coarse standard, suitable for matching nuts and bolts of the same designation.
How does the bottoming chamfer affect the depth I can thread in a blind hole?
The bottoming chamfer has only a short lead, letting you thread close to the bottom of a blind hole after a starter tap has begun the cut.
What clearance do I need for the 2 1/2 in overall length in my tap handle or fixture?
The tap measures two and a half inches overall, so your handle or holder must accommodate that full length plus room for turning.
