Overview
This threading tool, model POU1/8NPTW/DRILL, is sized for 1/8 inch NPT threads based on its model number, and comes as a 2 piece set.
The model code spells out its purpose: a drill and tap combination for cutting 1/8 inch NPT pipe threads. The brand is listed simply as Drill, and beyond the thread size and piece count the listing does not give material, coating or handle details, so pairing it correctly with a tap wrench or drill chuck depends on checking the actual dimensions on arrival.
- Model: POU1/8NPTW/DRILL, sized for 1/8 inch NPT
- Category: Tools, Threadings
- 2 piece set
Who it's for
Useful for anyone drilling and tapping a 1/8 inch NPT pipe thread in one job, such as fitting a pipe plug or sensor boss. Not a fit for other NPT sizes or non-pipe thread work, since the model number ties it specifically to 1/8 NPT.
Pros and cons
- Thread size stated clearly in the model number
- Comes as a matched 2 piece set
- Material and coating detail thin beyond model code
- Limited to 1/8 inch NPT thread size only
Performance notes
A drill and tap combination like this first bores the pilot hole, then cuts internal threads sized for a 1/8 NPT fitting. Getting a tight seal depends on drilling to the correct pilot size before tapping, which the listing does not spell out beyond the thread designation itself.
