Product Description
DRILLCO NITRO S&D Drill Set 1000N8 — 8-Piece Heavy-Duty HSS Set for Large-Diameter Hole Drilling
The DRILLCO NITRO 1000N8 is an 8-piece Spade & D (S&D) drill set covering 9/16" to 1" by 16ths, engineered for drilling large-diameter holes in low to medium strength materials with handheld power tools. Each drill is manufactured from premium grade M2 High Speed Steel and features a 1/2" reduced shank, making the full size range accessible through standard drill chucks. The 118° split point reduces walking at startup, and the black and gold surface treatment maximizes lubricity throughout the cut. This set is purpose-built for contractors and trades professionals who need reliable, heavy-duty performance in portable drilling applications.

Compared to conventional HSS drills, the NITRO S&D series delivers superior performance through its combination of M2 HSS construction, black and gold surface treatment for enhanced lubricity, and a 118° split point that eliminates the need for center-punching. The 1/2" reduced shank and 3-flat design make the full large-diameter range compatible with standard handheld drill chucks, removing the need for specialized equipment on the job site.
Key Features & Benefits
Premium Grade M2 High Speed Steel Construction
Each drill in the set is manufactured from M2 High Speed Steel, the same material used across the full NITRO line for heavy-duty drilling. This construction supports longer tool life and sustained performance across repeated use in demanding field conditions.
118° Split Point
The 118° split point is self-centering, reducing walking when starting a hole and enabling faster penetration without the need for a center punch. This is especially valuable when drilling large-diameter holes freehand with a portable drill.
Black and Gold Surface Treatment
The body and flute of each drill receive a black and gold surface treatment engineered for maximum lubricity. This treatment also provides better resistance to corrosion and breakage while reducing chipping and flaking during use.
1/2" Reduced Shank
All eight drills in the set feature a 1/2" reduced shank, allowing the full 9/16" to 1" size range to be used in standard drill chucks without requiring a larger chuck or specialized tooling. This keeps the set practical for everyday handheld power tool use on the job site.
3-Flat Shank Design
Three flats machined onto the shank provide a more secure grip in the drill chuck, reducing slippage during high-torque large-diameter drilling. This is particularly important when operating handheld power tools where chuck grip directly affects control and safety.
Heavy-Duty Construction for Extended Tool Life
The heavy-duty build of the NITRO S&D series is designed to increase both tool life and cutting performance relative to conventional HSS drills. Contractors drilling repetitive large-diameter holes benefit from fewer bit changes and more consistent results across the job.
Common Applications
Large-Diameter Hole Drilling
The 1000N8 set covers 9/16" to 1" by 16ths, making it the right choice when large through-holes are required in structural or fabricated components.
Drilling in Low to Medium Strength Materials
The NITRO S&D series is rated for low to medium strength materials, making it suitable for mild steels, general fabrication stock, and similar field materials encountered in construction and metalworking trades.
Handheld Power Tool Applications
The 1/2" reduced shank and 3-flat design are specifically engineered for use in handheld power drills, giving contractors the ability to drill large-diameter holes without a drill press or fixed spindle machine.
Fixed Spindle Applications
In addition to handheld use, the NITRO S&D drills are also designed for use in fixed spindle applications such as drill presses, providing versatility across shop and field environments.

Safety Data Summary
Hazard Information
- During normal operation, high speed steel products do not present inhalation, ingestion, or other chemical hazards.
- Grinding, cutting, machining, burning, or welding may release dusts, fumes, or vapors that 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 is listed as a carcinogen by NTP and OSHA; associated with dermatitis, inflammation/ulceration of the upper respiratory tract, and possibly cancer of nasal passages and lungs.
- Tungsten: some evidence of pulmonary involvement such as cough.
- Vanadium: eye and respiratory tract irritant.
- Cobalt dust is identified as the most probable cause of respiratory diseases including occupational asthma and interstitial fibrosis.
- 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
- Cloth or leather gloves recommended when contact with dust or mist is likely.
- Wear safety glasses or goggles with side shields; contact lenses should not be worn when handling these materials.
- Hearing protection may be required.
- Always use machine guards and wear safety glasses and protective clothing to prevent injury in the event of tool breakage.
- Use an appropriate NIOSH-approved respirator if airborne dust concentration exceeds the applicable PEL or TLV.
- Use local exhaust ventilation adequate to limit personal exposure to airborne dust below PEL or TLV levels.
Safe Handling
- Perform grinding, welding, and dust-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, rags, or other items to remove dust — remove dust by washing or vacuuming with appropriate filters.
- Clean up spills using methods that avoid dust generation: vacuum with appropriate filters, wet dust mop, or wet clean-up.
- Store in a dry place in a manner that prevents accidental environmental contamination from traces of industrial lubricants or wetting oils.
- Soiled clothing should be laundered separately.
- Incompatible with strong acids and strong oxidizers.
- Dispose of in compliance with federal, state/provincial, and local environmental regulations, or send to an appropriate reclamation facility.
Frequently Asked Questions
Q: What sizes are included in the 1000N8 set?
A: The 1000N8 set contains 8 drills ranging from 9/16" to 1" by 16ths.
Q: Will these drills fit in a standard 1/2" drill chuck?
A: Yes. All drills in the set feature a 1/2" reduced shank, so the full size range — including the larger diameters — fits in a standard 1/2" drill chuck.
Q: What is the overall length of each drill in the set?
A: Each drill has an overall length of 6".
Q: What materials are these drills rated for?
A: The NITRO S&D series is designed for drilling in low to medium strength materials. The black and gold surface treatment is noted as suitable for most materials.
Q: Why does the split point matter for large-diameter drilling?
A: The 118° split point reduces walking when starting a hole, which is especially important when drilling large-diameter holes freehand with a handheld power tool where precise starting position is critical.
Q: What is the purpose of the 3-flat shank?
A: The 3 flats machined onto the shank provide a more secure grip in the drill chuck, reducing slippage during the high-torque demands of large-diameter drilling with handheld power tools.
