Drillco 25A324P 2-3/8-8 HSS Plug Tap
Drillco 25A324P supplies the 2-3/8-8 thread size for large-diameter tapping. Its reduced neck addresses clearance behind the cutting section, while the eight-TPI pitch remains distinct from nearby taps with the same pitch but a different nominal diameter.
Specifications and included details
- 2-3/8-inch nominal thread diameter with eight threads per inch.
- High-speed steel plug tap with black oxide finish.
- Reduced-neck construction.
- Listed spiral-point design directs chips ahead of the cutting section.
Before ordering
Match the complete 2-3/8-8 thread specification and confirm the required direction. Check tap dimensions and holder capacity, which are not itemized here. Establish chip clearance and full-thread depth for the intended hole rather than treating reduced neck as an unlimited-depth rating.
Product questions and answers
Will it cut a 2-1/4-8 thread?
No. Although both use eight TPI, this tap's nominal thread diameter is 2-3/8 inches.
Does reduced neck specify a maximum hole depth?
No. It describes the neck construction. Verify the actual tool dimensions and required thread depth.
Is spiral point the same as spiral flutes?
No. Point geometry and flute form are different specifications. The supplied record identifies a spiral point without establishing spiral-flute construction.
