Drillco 25A264P 2-Inch 8-TPI HSS Plug Tap
Drillco 25A264P is the 2-inch, eight-threads-per-inch version of this large plug-tap format. It should be chosen for its exact thread identity, rather than treated as interchangeable with the larger 2-5/8-inch tap that shares similar product wording.
Specifications and included details
- 2-inch nominal thread diameter and 8 TPI, model 25A264P.
- HSS construction and black oxide finish.
- Plug chamfer, reduced neck and square shank described.
- Spiral-point chip evacuation and USA manufacture listed.
Before ordering
Confirm the thread form, class, direction and tap-drill size for the required internal thread. Verify holder fit from actual shank dimensions. Chip evacuation and available hole depth determine whether this geometry suits the application.

Does 2-8 establish all thread specifications?
It gives nominal diameter and TPI. Verify the required thread form, class and direction before selecting the tap.
Is a tap wrench included?
No holder is established in the tap's inventory. Confirm suitable tooling separately.
