NITRO® S&D Drill Bit Set 1000N

DRILLCO NITRO® S&D Drill Bit Set 1000N — Heavy-Duty HSS Large-Diameter Drilling in 32 Pieces

The DRILLCO NITRO® S&D Drill Bit Set (Item #1000N32) is a 32-piece spade-and-drill (S&D) set covering sizes from 1/2" to 1", purpose-built for drilling large-diameter holes in low to medium strength materials with handheld power tools. Every bit is manufactured in the United States from premium grade M2 High Speed Steel and features a 1/2" reduced shank so the full size range fits standard drill chucks without adapters. The 118° split point and black-and-gold surface treatment combine to reduce walking at startup and maximize lubricity throughout the cut, extending tool life in demanding field conditions.

Technical Specifications

Available Items

Unlike standard jobber-length HSS drills, the NITRO® S&D series is engineered specifically for large-diameter hole-making with a 6" overall length and 1/2" reduced shank that works in any standard chuck — eliminating the need for specialty tooling or adapters. The black-and-gold surface treatment goes beyond basic black oxide, providing better corrosion resistance and lubricity than conventional finishes, while the 3-flat shank design prevents slippage that is common when running large-diameter bits in handheld drills.

Key Features & Benefits

Premium Grade M2 High Speed Steel Construction

Every bit in the set is made from M2 HSS, the same premium alloy used across the full NITRO® line. This material provides the hardness and wear resistance needed for heavy-duty drilling across a wide range of material groups, translating to longer tool life between replacements on the job site.

118° Split Point for Reduced Walking

The 118° split point is self-centering, allowing the bit to begin cutting immediately without the drill skating across the workpiece surface. This is especially valuable when starting large-diameter holes freehand, where maintaining position is critical to hole accuracy.

Black and Gold Surface Treatment for Maximum Lubricity

The black-and-gold surface treatment reduces friction between the bit and the workpiece, helping to deflect heat during the cut. Reduced heat buildup protects the cutting edge and extends the usable life of each bit compared to untreated or basic black oxide finishes.

1/2" Reduced Shank — Fits Standard Drill Chucks

All 32 bits share a 1/2" reduced shank, meaning the entire 1/2"–1" size range can be used in any standard 1/2" drill chuck without special adapters or equipment. This makes the set immediately deployable with tools contractors already own.

3-Flat Shank for Secure Chuck Grip

Three flats machined into the shank give the chuck jaws positive purchase, preventing the bit from spinning in the chuck under the high torque loads generated when drilling large-diameter holes. This reduces the risk of slippage-related damage to both the bit and the workpiece.

Heavy-Duty Construction for Extended Tool Life

The heavy-duty build of the NITRO® S&D series is designed to withstand the demands of repeated large-diameter drilling in field conditions. Contractors get a set that holds up through sustained use rather than requiring frequent bit replacement mid-project.

Common Applications

Drilling Large Diameter Holes

The S&D configuration and 1/2"–1" size range make this set the go-to choice when large through-holes or clearance holes are required in structural or fabricated components.

Drilling in Low to Medium Strength Materials

The NITRO® 1000N set is optimized for low to medium strength materials, covering the broad range of mild steels, structural steel, and similar metals commonly encountered in construction and fabrication work.

Handheld Power Tool Applications

The 1/2" reduced shank, 3-flat shank design, and 6" overall length are specifically configured for use with handheld power drills, giving tradespeople the reach and chuck compatibility needed for field drilling operations.

Fixed Spindle Applications

In addition to handheld use, the NITRO® S&D drills are designed for use in fixed spindle applications such as drill presses, providing versatility across both portable and stationary setups.

Compatible Materials

• Low to medium strength steels

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 12–48 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 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, cutting, machining, burning, and welding operations in well-ventilated areas.
• Clean up using methods that avoid dust generation: vacuum with appropriate filters, wet dust mop, or wet clean-up.
• Store in a dry place; store in a manner that prevents accidental environmental contamination from traces of industrial lubricants or wetting oils.
• 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.
• Soiled clothing should be laundered separately.
• Incompatible materials: strong acids, strong oxidizers.

Frequently Asked Questions

Q: What size range does the 1000N32 set cover?
A: The set covers 1/2" through 1" in diameter and contains 32 pieces.

Q: Will these bits fit my standard 1/2" drill chuck?
A: Yes. All bits in the set have a 1/2" reduced shank, so the entire 1/2"–1" size range fits any standard 1/2" drill chuck without adapters.

Q: Can these drills be used in both handheld drills and drill presses?
A: Yes. The NITRO® S&D drills are designed for use in portable handheld power drills as well as fixed spindle applications such as drill presses.

Q: What is the split point angle, and why does it matter?
A: The split point is 118°. This geometry is self-centering, reducing walking when starting a hole and allowing faster penetration compared to a conventional point — particularly useful when drilling freehand with a handheld tool.

Q: What materials are these bits made from?
A: Each bit is made from premium grade M2 High Speed Steel (HSS), manufactured in the United States, and surface-treated with a black-and-gold finish for maximum lubricity.

Q: What is the overall length of the bits in this set?
A: All bits in the 1000N S&D series are 6" in overall length.
