DRILLCO 2700C 12 PC Pipe Tap & Die Set — Complete NPT Threading Solution
The DRILLCO 2700C is a 12-piece carbon steel pipe tap and die set engineered to produce tight-sealing NPT threads on pipe and pipe fittings. It combines six taper pipe taps and six matching pipe dies in a single organized set, covering thread sizes from 1/8" NPT through 1" NPT. Designed for both internal and external pipe threading, this set is suited for plumbing, mechanical, and pipefitting contractors who need to cut new threads or rethread existing connections. Applications include cutting threads in through holes, blind holes, and rethreading damaged or worn pipe fittings.

| 2700C12 | Pipe Tap & Die Set Carbon | 12 pc |
The 2700C brings both internal (tap) and external (die) pipe-threading capability into one organized set, eliminating the need to source taps and dies separately. The matched taper pipe tap and die sizes ensure consistent NPT thread geometry across the full 1/8" through 1" range, making it a practical all-in-one solution for pipe threading and rethreading tasks on the job site.
Key Features & Benefits
Carbon Steel Construction
Carbon steel provides the hardness needed to cut threads in mild steel pipe and pipe fittings. For contractors handling standard plumbing and mechanical piping, this material offers a cost-effective balance of durability and cutting performance.
Complete Tap and Die Pairing
Each of the six NPT sizes is represented by both a taper pipe tap and a matching pipe die, giving the user a full internal and external threading solution in a single set. This eliminates the need to purchase taps and dies separately and ensures size consistency across the set.
Full NPT Size Range (1/8" through 1")
Covering six standard NPT sizes — 1/8-27, 1/4-18, 3/8-18, 1/2-14, 3/4-14, and 1-11-1/2 — this set addresses the most common pipe thread sizes encountered in plumbing, HVAC, and mechanical piping work. Having the full range on hand reduces downtime from missing tooling.
Tight-Sealing Taper Thread Design
The taper pipe tap geometry is designed to produce a tight sealing thread, which is critical for leak-free connections in pressurized pipe systems. This makes the set appropriate for applications where thread integrity directly affects system performance.
Common Applications
Pipe Thread Cutting
Used to cut new NPT threads on pipe ends and pipe fittings, enabling secure, leak-resistant connections in plumbing and mechanical systems.
Thread Rethreading and Repair
Designed for rethreading damaged or worn threads on existing pipe and fittings, restoring thread integrity without replacing the entire fitting or pipe section.
Through-Hole Threading
The taper pipe taps are suitable for cutting internal threads in through holes, accommodating standard pipe fitting installations.
Blind-Hole Threading
The set is also applicable for cutting threads in blind holes, expanding its utility across a range of pipe fitting configurations.
Compatible Materials
- Threaded pipe
