NITRO® 1035N 29 PC Jobber Drill Set

NITRO® 1035N 29 PC Jobber Drill Set — Premium HSS Heavy-Duty Performance

The DRILLCO NITRO® 1035N is a 29-piece jobber drill set (NAS Type B) engineered for heavy-duty drilling in medium and high strength materials. Built from premium grade High Speed Steel (HSS) with a 135° split point and black and gold surface treatment, this set is designed to outperform standard HSS drills in demanding jobsite conditions. The 3/8" reduced shank accommodates a wide range of chuck sizes, making it suitable for both handheld power tools and CNC operations. Covering sizes from 1/16" to 1/2" by 64ths, this set provides contractors with a comprehensive range for drilling large diameter holes across a variety of applications.

Technical Specifications

Available Sizes

Unlike standard HSS jobber drills, the NITRO® 1035N features a black and gold surface treatment that provides better corrosion resistance, improved lubricity, and reduced chipping and flaking compared to bright finish or black oxide alternatives. The 135° split point design offers self-centering capability that standard 118° conventional point drills do not provide, reducing walking and thrust requirements — a meaningful advantage when drilling on curved surfaces or with handheld tools.

Key Features & Benefits

Premium Grade HSS Construction

Made with premium grade High Speed Steel, these drills are built to last longer than standard HSS alternatives. For contractors drilling frequently into medium and high strength materials, longer tool life means fewer bit changes and lower cost per hole.

135° Self-Centering Split Point

The 135° split point is self-centering, which reduces thrust requirements and minimizes walking at the start of a hole. This is especially valuable when drilling on curved or irregular surfaces, or when working with handheld power tools where precise starting position is harder to control.

Black and Gold Surface Treatment

The black and gold surface treatment provides maximum lubricity while offering better resistance to corrosion and breakage. It also reduces chipping and flaking, extending the usable life of each drill bit across a wide range of materials.

3/8" Reduced Shank

The 3/8" reduced shank allows larger diameter bits in this set to be used in standard 3/8" chucks, expanding compatibility with common handheld power tools on the jobsite. This eliminates the need for a larger chuck to access the full size range of the set.

Comprehensive 29-Piece Size Range

Covering 1/16" to 1/2" by 64ths, this set gives contractors access to every increment needed for a wide variety of hole sizes in a single kit. Having the full range on hand reduces downtime spent sourcing individual bits.

Suitable for Handheld and CNC Operations

The NITRO® 1035N is designed for use in both handheld power tools and CNC operations, making it a versatile choice for contractors who work across multiple setups. This dual suitability means the same set can be used in the field and in a shop environment.

Common Applications

Drilling in Medium and High Strength Materials

The premium HSS construction and 135° split point make this set well-suited for drilling into medium and high strength steels and similar materials where standard drills may wear prematurely.

Heavy-Duty Drilling

The heavy-duty design of the NITRO® series increases tool life and performance under demanding drilling conditions, making it appropriate for high-volume or repetitive drilling tasks on construction and fabrication projects.

Drilling Large Diameter Holes

With sizes up to 1/2", this set covers large diameter hole requirements. The 3/8" reduced shank ensures these larger bits remain compatible with standard chuck sizes.

Handheld Power Tool Operations

The self-centering split point and reduced shank design make this set particularly effective for use with handheld power tools, where controlling bit walk and maintaining chuck compatibility are key concerns.

CNC Operations

The NAS Type B jobber drill specification and consistent premium HSS construction make these drills suitable for use in CNC drilling operations where repeatability and tool life are critical.

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 that 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 is listed as a carcinogen by NTP and OSHA; various forms of dermatitis, inflammation and/or ulceration of the upper respiratory tract, and possibly cancer of nasal passages and lungs are associated with chromium exposure.
• 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.
• Skin contact with dust can cause irritation or allergic skin rash due to cobalt sensitization.
• NFPA Hazard Rating: Health 1; Flammability 0; Reactivity 0.
• Fine metal particles produced when ground or sawed can burn; high concentrations in air may present an explosion hazard.

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 appropriate PEL or TLV.
• Hearing protection might be required.
• Always use machine guards and wear safety glasses and protective clothing to prevent injury in the event of tool breakage.
• Soiled clothing should be laundered separately.
• Employer should provide an eye wash station within the immediate work area for emergency use.

Safe Handling

• Use only with local exhaust ventilation adequate to limit personal exposure to airborne dust to levels that do not exceed the PEL or TLV.
• 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 the end of the 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 to avoid dust generation such as vacuum (with appropriate filters), wet dust mop, or wet clean up.
• Incompatible materials: Strong Acids, Strong Oxidizers.
• For powder fires, smother with dry sand, dry dolomite, ABC type fire extinguisher, or flood with water.

Frequently Asked Questions

Q: What materials is the NITRO® 1035N designed to drill into?
A: This set is designed for drilling holes in medium and high strength materials and is suitable for heavy-duty drilling and drilling large diameter holes. The black and gold surface treatment is noted as suitable for most materials.

Q: What is the shank size, and will these bits fit my standard drill chuck?
A: All bits in this set have a 3/8" reduced shank, which allows the larger diameter bits to be used in standard 3/8" chucks commonly found on handheld power tools.

Q: What size range does the 29-piece set cover?
A: The set covers 1/16" to 1/2" by 64ths, providing every 64th-inch increment across that range in a single 29-piece kit.

Q: Why choose a 135° split point over a standard 118° conventional point?
A: The 135° split point is self-centering, which reduces thrust requirements and minimizes walking at the start of a hole. According to Drillco's linecard, this design is best for curved surfaces and hand-drilling on harder materials, whereas a 118° conventional point is suited for mild steels and free machining materials.

Q: Can these drills be used in CNC machines as well as handheld tools?
A: Yes. The NITRO® 1035N is described as ideal for both handheld and CNC operations.

Q: What role do speed, feed, and lubrication play when using these drills?
A: According to Drillco, speed, feed, and lube are all critical to cutting tool performance. Proper attention to these factors will help maximize tool life and cutting efficiency.
