Industrial Taps & Dies Built For Heavy Duty Use
Since 1940, Century Drill & Tool has supplied global tool importers, hardware buying groups, OEM manufacturers, and industrial suppliers with durable threading tools engineered to maintain precise thread geometry under intense operational stress.
Our industrial taps and dies are precision-ground from high-speed steel (HSS) and high-carbon steel alloys to withstand high friction, work-hardening metals, and severe torque requirements. Whether creating internal threads in blind holes, chasing damaged external studs, or conducting repair tasks in maintenance bays, Century provides complete thread accuracy across fractional, metric, and specialized pipe pitches.
- Accurate Thread Profiles: Precision-ground flutes provide fast chip removal and clean, burr-free threads.
- Comprehensive Sizing: Full catalog coverage across UNC (NC), UNF (NF), Metric coarse/fine, and NPT pipe sizes.
- Industrial Packaging Options: Durable blow-molded cases, plastic sleeve index packages, and bulk B2B packing options.
- Rigorous ISO Quality Control: Every batch undergoes Rockwell hardness verification and pitch diameter gauge inspection.

Tap & Die Selection & Engineering Guide
Selecting the correct tap style and thread geometry guarantees superior thread strength and prevents tool breakage during production.
| Tool Category | Material / Alloy | Thread Spec | Ideal Application | B2B Procurement Advantage |
|---|---|---|---|---|
| HSS Hand & Machine Taps | M2 High-Speed Steel | UNC / UNF / Metric Class 2B | Through-hole and blind-hole tapping in alloy steel, stainless, and aluminum. | Long tool life under high cutting speeds; precise pitch tolerances. |
| Hex Rethreading Dies | Heat-Treated Carbon Steel | NC, NF & ISO Metric | Restoring bruised, rusted, or cross-threaded external bolts and studs. | Fits standard hex sockets or wrenches; no specialized die stock required. |
| Round Adjustable Dies | Alloy Tool Steel | ANSI Standard Dies | Cutting new external threads on rods, shafts, or custom hardware components. | Adjustable pitch diameter screw for custom thread fit setting. |
| Nu-Thred Restoring Files | Special Hardened Tool Steel | 8 Pitches per File | Immediate restoration of damaged male threads on shafts, axles, and pipe fittings. | Universal pitch coverage eliminates need for carrying individual dies. |
| Tap Socket Sets | Chrome Vanadium (Cr-V) | Fits Standard 3/8" & 1/4" Ratchets | Tapping in restricted spaces where standard T-handle wrenches cannot rotate. | Increases operational efficiency in automotive and maintenance bays. |

Technical FAQs
Frequently Asked Questions
Our cutting taps and dies are precision machined from premium High-Speed Steel (M2 HSS) and carbon steel alloys depending on the operational requirement. HSS taps offer superior wear resistance, heat tolerance, and edge retention during continuous machine production and tough alloy tapping.
Cutting dies feature sharp rake angles designed to cut brand-new threads onto raw cylindrical stock. Rethreading dies are hex-shaped and designed to repair, clean, and reform damaged or rusty existing threads without removing sound parent metal.
Yes. We support custom packaging options including heavy-duty blow-molded index cases, clam-shells, metal storage racks, and custom barcode packaging designed for international hardware retailers and industrial supply distributors.
UNC (Coarse Thread) tools are ideal for general structural applications, rapid assembly, and soft materials like aluminum or cast iron. UNF (Fine Thread) tools provide higher tensile strength and finer adjustment, making them suited for automotive, aerospace, and precision machinery applications.
