2000E 40 PC Tap & Die Set

DRILLCO 2000E 40-Piece Tap & Die Set — Complete HSS Threading Assortment for Inch Sizes

The DRILLCO 2000E is a 40-piece high-speed steel tap and die set designed for contractors and trades professionals who need a comprehensive inch-series threading solution in a single kit. The set covers NC and NF thread types from 4-40 through 1/2", and includes a 1/8" NPT size for pipe thread applications. Round adjustable dies provide flexibility for fine-tuning thread fit, and the included hand tools — three tap wrenches, one die stock, one pitch gauge, and one screwdriver — mean the kit is ready to use straight out of the case without sourcing additional accessories.

Technical Specifications

Available Items

Unlike basic tap-only or die-only assortments, the 2000E delivers a matched set of both taps and dies across the full common inch-size range, eliminating the need to source complementary tools separately. The inclusion of a pitch gauge and three tap wrenches in varying sizes means the kit supports a wider range of fastener sizes without requiring additional tooling investment. The round adjustable die design allows on-the-fly thread diameter adjustment, a practical advantage when fitting threads to existing hardware in the field.

Key Features & Benefits

High-Speed Steel Construction

HSS is the industry-standard material for general-purpose threading tools, offering the hardness needed to cut clean threads in low-to-medium tensile strength steels, aluminum, and other common construction metals. For contractors working across varied material types on a single job, HSS provides reliable performance without the brittleness associated with carbide tooling.

Comprehensive NC/NF Size Range (4-40 through 1/2")

Covering the most commonly encountered inch-series thread sizes in a single kit reduces the need to carry multiple individual taps and dies to the job site. Both National Coarse and National Fine thread forms are represented, giving the user flexibility to match the thread specification of existing fasteners or hardware.

1/8" NPT Pipe Thread Included

The addition of a 1/8" NPT tap and die extends the set's utility to pipe fitting and fluid system work, which frequently arises in mechanical, plumbing, and HVAC applications. Having the NPT size integrated into the same kit avoids the need for a separate pipe tap set for the most common small pipe thread size.

Round Adjustable Dies

Adjustable round dies allow the user to fine-tune the thread diameter to achieve the desired fit class or to compensate for material variations. This adjustability is particularly useful when threading rod or bolt stock where a precise fit to a mating nut is required.

Complete Hand Tool Complement

Three tap wrenches accommodate the range of tap shank sizes across the 4-40 to 1/2" size range, while the included die stock, pitch gauge, and screwdriver provide everything needed for setup, threading, and thread identification without sourcing additional accessories. This self-contained approach reduces setup time and tool bag clutter on the job site.

Common Applications

Thread Repair

Damaged or stripped threads on bolts, studs, and tapped holes can be restored using the matching tap and die sizes in this set, covering the most common inch-series fastener sizes encountered in structural and mechanical work.

New Thread Cutting in Metal Stock

The dies can be used to cut new external threads on rod or bolt stock in NC or NF specifications from 4-40 through 1/2", suitable for fabricating custom fasteners or threaded components in the field.

Tapping New Holes

The included taps allow contractors to cut internal threads in pre-drilled holes across the full size range, enabling the use of machine screws and bolts where no thread previously existed.

Pipe Thread Applications

The 1/8" NPT tap and die support threading of small-diameter pipe fittings and connections, applicable in plumbing, pneumatic, and hydraulic system work.

Thread Identification

The included pitch gauge allows quick identification of unknown thread pitches on existing fasteners or hardware, reducing the risk of cross-threading or mismatched fastener selection on the job site.

Safety Data Summary

Hazard Information

• Under normal use, HSS cutting tools do not present inhalation, ingestion, or chemical hazards.
• Grinding, cutting, machining, burning, or welding these tools may release dusts, fumes, or vapors that can 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, chills, and fever persisting 12–48 hours.
• Chromium (present 0–5% by weight) is listed as a carcinogen by NTP and OSHA; various forms of dermatitis and upper respiratory tract inflammation are associated with chromium exposure.
• Tungsten (5–10% by weight): some evidence of pulmonary involvement such as cough.
• Vanadium (0–5% by weight): eye and respiratory tract irritant.
• Cobalt dust (a component of HSS alloys) is associated with respiratory diseases including occupational asthma and interstitial fibrosis.
• Skin contact with dust may cause irritation or allergic skin rash due to cobalt sensitization.
• Fine metal particles produced during grinding 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 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 may be required depending on the operation.
• 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.

Safe Handling

• Perform grinding, welding, or fume-generating operations in well-ventilated areas with local exhaust ventilation.
• Wash hands thoroughly after handling and before eating or smoking; wash exposed skin at end of work shift.
• Do not shake clothing or rags 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 industrial lubricants or wetting oils.
• Clean up spills using methods that avoid dust generation: vacuum with appropriate filters, wet dust mop, or wet clean-up.
• Soiled clothing should be laundered separately.
• Incompatible materials: strong acids, strong oxidizers.
• For powder fires: smother with dry sand, dry dolomite, ABC-type fire extinguisher, or flood with water. Do not release fire control runoff to swales or waterways.
• First aid — Inhalation: remove from exposure and seek medical attention if pulmonary symptoms develop. Skin: wash with soap and water; seek medical attention if irritation persists. Eyes: flush with copious water; seek medical attention if irritation persists. Ingestion: dilute with water, induce vomiting, seek medical attention.
• Persons with pre-existing respiratory disease may be at increased risk from exposure.
