200A 60 PC Drill Bit Set

DRILLCO 200A60 — 60-Piece Wire Gauge Drill Bit Set (#1–#60) for General Purpose HSS Drilling

The DRILLCO 200A60 is a 60-piece high speed steel (HSS) jobber-length drill bit set covering the full wire gauge range from #1 through #60, designed for general purpose drilling in low to medium tensile strength materials. Made in the United States, these bits feature a 118° conventional point for rapid penetration and a black oxide surface treatment that reduces friction, inhibits chip welding, improves chip flow, and increases abrasion resistance. The set is suited for contractors and trades professionals who need a comprehensive wire gauge assortment on hand for a wide range of drilling tasks. Speed, feed, and lubrication are all critical to cutting tool performance with this series.

Technical Specifications

Available Sizes

Unlike bright-finish HSS bits suited only for soft metals and non-ferrous materials, the black oxide surface treatment on the 200A60 series actively reduces friction and heat damage, extending tool life on low to medium tensile strength materials. Jobber length provides the extra reach needed for most drilling applications while maintaining the rigidity required for accurate hole placement, making this set a more versatile choice than shorter screw machine length alternatives.

Key Features & Benefits

General Purpose HSS Construction

High speed steel is the most commonly used tool material for general purpose drilling, suitable for low to medium strength steels, aluminum and other non-ferrous materials, as well as wood and plastic. This makes the 200A60 a reliable all-around set for contractors who encounter a variety of materials on the job.

Black Oxide Surface Treatment

The black oxide finish reduces friction and heat damage during drilling, which helps prevent chip welding to the cutting edge and improves chip flow out of the hole. The result is increased abrasion resistance and longer tool life compared to uncoated bright-finish bits on low to medium tensile strength materials.

118° Conventional Point

The 118° conventional point is optimized for rapid penetration into mild steels and free-machining materials. This geometry is the standard choice for general purpose drilling where a self-centering split point is not required.

Jobber Length

Jobber length is the most common drill length because it provides extra reach while remaining usable in the majority of drilling applications. This length strikes the right balance between rigidity and versatility for everyday contractor use.

Complete Wire Gauge Range (#1–#60)

Having all 60 wire gauge sizes in a single set eliminates the need to source individual bits for precision hole sizing tasks. This is particularly valuable when matching hole diameters to specific fastener or tap requirements across a job.

Common Applications

General Purpose Drilling in Low to Medium Strength Materials

The 200A60 set is designed for everyday drilling tasks in materials such as mild steel, aluminum, and other low to medium tensile strength metals encountered in construction and fabrication work.

Wire Gauge Hole Sizing

The full #1–#60 wire gauge range allows contractors to drill precisely sized holes for tapping, fastener clearance, or other applications requiring specific wire gauge diameters.

Drilling in Non-Ferrous Materials

HSS construction makes these bits suitable for drilling aluminum and other non-ferrous materials commonly found in HVAC, electrical, and general construction applications.

Drilling in Wood and Plastic

General purpose HSS bits are suitable for use in wood and plastic, making this set useful across multiple trades and material types on a job site.

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 (present 0–5% by weight) is listed as a carcinogen by NTP and OSHA; associated with dermatitis, upper respiratory tract inflammation/ulceration, and possible nasal/lung cancer risk.
• 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 (if generated) is associated with respiratory diseases including occupational asthma and interstitial fibrosis.
• Skin contact with dust can cause irritation or allergic skin rash due to cobalt sensitization.
• Eye contact with dust may cause irritation.
• 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 may 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, welding, or dust-generating operations in well-ventilated areas; use local exhaust ventilation adequate to keep airborne dust below PEL/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.
• 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 materials: strong acids, strong oxidizers.
• For powder fires: smother with dry sand, dry dolomite, ABC-type fire extinguisher, or flood with water.
