IRWIN 1749 M14 x 1.25 mm HCS Plug Tap
IRWIN 1749 is the M14 x 1.25 mm plug tap, a finer-pitch identity than the separately listed M14 x 1.50 mm model. Match the thread pitch as well as nominal diameter when selecting it for a new internal thread or a repair.
Specifications and included details
- M14 nominal diameter with 1.25 mm metric pitch.
- High-carbon steel construction and plug-style chamfer.
- Four straight flutes and right-hand metric thread.
- Bulk quantity is one tap; size markings described on the tool.
Before ordering
Verify the existing or specified thread and the appropriate tap-drill diameter. Check available thread depth and chip clearance. Plug geometry does not guarantee full threads to the bottom of a blind hole, and a different M14 pitch is not interchangeable.
Product questions and answers
Can I substitute this for an M14 x 1.50 mm tap?
No. The nominal diameter matches, but 1.25 and 1.50 mm pitches produce different threads.
Does bulk mean several taps are supplied?
No. The explicit included quantity is one tap.
Is the required drill size stated numerically here?
No numerical tap-drill diameter is established in these details. Verify it from an appropriate chart for the thread and application.
