2000A & 3350E 63 PC Tap & Die Set

DRILLCO 2000A & 3350E 63-Piece Tap & Die Set — Complete NC/NF Threading Solution

The DRILLCO 2000H63 is a 63-piece tap and die set engineered for contractors and trades professionals who need a comprehensive threading solution covering the full range of common NC (National Coarse) and NF (National Fine) thread sizes. The set includes High Speed Steel (HSS) taps and carbon steel hexagon dies spanning fractional sizes from 4-40 through 1-inch, plus NPT pipe thread sizes. Two included tap wrenches — an adjustable model and a T-handle model — provide the tooling needed to drive every tap in the set by hand. Made in the United States by DRILLCO, this set is suited for thread cutting, thread repair, and bolt-threading tasks across a wide variety of metalworking and construction applications.

Technical Specifications

Unlike sets that cover only a narrow range of fractional sizes, the 2000H63 spans from 4-40 all the way through 1-inch in both coarse and fine pitches, plus NPT pipe thread sizes — eliminating the need to source supplemental taps or dies for common job-site threading tasks. The combination of HSS taps and carbon steel hexagon dies, along with two included wrenches covering the full size range of the set, makes this a self-contained threading kit ready for immediate use.

Key Features & Benefits

High Speed Steel Taps

HSS taps offer greater hardness and wear resistance compared to carbon steel taps, allowing them to cut threads in a wider range of materials including low to medium tensile strength steels, aluminum, and other non-ferrous metals. For contractors cutting threads in varied field conditions, HSS construction helps maintain cutting edge integrity over repeated use.

Carbon Steel Hexagon Dies

The hexagon die profile allows standard wrenches and die stocks to engage the die securely, providing positive torque transfer during thread cutting and repair. Carbon steel construction is well suited for threading mild steels and softer materials commonly encountered in general construction and maintenance work.

Dual Tap Wrench Inclusion

The set includes both an adjustable tap wrench (ranging #7 to 1/2" and 1/4" to 1") and a T-handle tap wrench (ranging #0 to 3/8"), ensuring every tap in the set can be driven without sourcing additional tooling. The T-handle wrench provides better feel and control for smaller tap sizes where breakage risk is higher.

Comprehensive NC/NF Size Coverage

With 28 distinct thread sizes spanning 4-40 through 1-12 in both coarse and fine pitches, plus 1/8-27 and 1/4-18 NPT pipe sizes, this set covers virtually every standard fastener thread a contractor is likely to encounter. Having the full range on hand reduces job-site delays caused by missing tap or die sizes.

NPT Pipe Thread Sizes Included

The inclusion of 1/8-27 and 1/4-18 NPT taps and dies extends the set's utility to pipe fitting and plumbing thread work, which is a common requirement in mechanical, HVAC, and general construction trades. NPT tapered threads provide a tight seal when properly cut, making these sizes essential for fluid and gas line work.

Made in the United States

Domestic manufacture supports consistent quality control and traceability of materials. For contractors working on projects with domestic content requirements, U.S.-made tooling from DRILLCO satisfies those specifications.

Common Applications

Thread Cutting in New Stock

Use the HSS taps to cut internal threads in drilled holes in mild steel, aluminum, and other non-ferrous materials for fastener installation in fabricated assemblies or structural connections.

Thread Repair and Restoration

Damaged or corroded threads on bolts, studs, and tapped holes can be cleaned up and restored using the matching tap or die from the set, avoiding the need to replace fasteners or re-drill and re-tap holes.

Bolt Threading and Re-Threading

The carbon steel hexagon dies allow contractors to cut external threads on rod stock or to restore damaged bolt threads across the full range of NC and NF sizes included in the set.

Pipe Thread Cutting and Repair

The 1/8-27 and 1/4-18 NPT sizes enable cutting and repairing tapered pipe threads in fittings and pipe ends for plumbing, HVAC, and mechanical piping applications.

General Maintenance and MRO Work

The broad size range makes this set a practical all-in-one threading kit for maintenance, repair, and operations work where a wide variety of fastener sizes may be encountered across equipment and structures.

Safety Data Summary

Hazard Information

• During normal operation and usage, high speed steel products do not present inhalation, ingestion, or other chemical hazards.
• Operations such as grinding, cutting, machining, burning, and welding may release dusts, fumes, or vapors which may present health hazards if exposure limits are exceeded.
• Excessive inhalation of metallic fumes and dusts may cause irritation of eyes, nose, and throat; symptoms may include metallic taste, dryness and irritation of the throat, chills, and fever persisting 12 to 48 hours.
• Chromium (present 0–5% by weight): listed as a carcinogen by NTP and OSHA; associated with dermatitis, inflammation and/or ulceration of the upper respiratory tract, and possibly cancer of nasal passages and lungs.
• Tungsten (present 5–10% by weight): some evidence of pulmonary involvement such as cough.
• Vanadium (present 0–5% by weight): eye and respiratory tract irritant.
• Cobalt dust (from grinding) is reported as the most probable cause of respiratory diseases including occupational asthma and interstitial fibrosis.
• Skin contact with dust can cause irritation or allergic skin rash due to cobalt sensitization.
• Fine metal particles produced when ground or sawed can burn; high concentrations in air may present an explosion hazard.
• NFPA Hazard Rating: Health 1; Flammability 0; Reactivity 0.

Personal Protective Equipment

• Wear safety glasses or goggles with side shields; do not wear contact lenses when handling these materials.
• Cloth or leather gloves are recommended when contact with dust or mist is likely.
• Use an appropriate NIOSH-approved respirator if airborne dust concentration exceeds the applicable PEL or TLV.
• Hearing protection might be required.
• Always use machine guards and wear protective clothing to prevent injury in the event of tool breakage.
• Employer should provide an eye wash station within the immediate work area for emergency use.

Safe Handling

• Perform grinding, cutting, and machining operations in well-ventilated areas; use local exhaust ventilation adequate to limit airborne dust below PEL or TLV levels.
• Wash hands thoroughly after handling and before eating or smoking; wash exposed skin at end of work shift.
• Do not shake clothing, rags, or other items to remove dust — remove dust by washing or vacuuming with appropriate filters.
• Store in a dry place in a manner that prevents accidental environmental contamination from traces of industrial lubricants or wetting oils.
• Clean up spills using methods that avoid dust generation such as vacuum (with appropriate filters), wet dust mop, or wet clean-up.
• Incompatible with strong acids and strong oxidizers.
• For powder fires: smother with dry sand, dry dolomite, ABC-type fire extinguisher, or flood with water; do not release runoff from fire control to swales or waterways.
• Soiled clothing should be laundered separately.
• If inhalation symptoms develop (coughing, wheezing, shortness of breath), remove from exposure and seek medical attention.
• If eye irritation occurs, flush with copious amounts of water; if irritation persists, seek medical attention.
