1000A 32 PC S&D Drill Bit Stand Set

DRILLCO 1000A 32-Piece S&D Drill Bit Stand Set — Expanded Capacity for 1/2" Portable Drill Chucks

The DRILLCO 1000A 32-piece S&D (Silver and Deming) drill bit stand set is a premium grade HSS drill bit collection designed to expand the size range capacity of a standard 1/2" portable drill chuck. Covering sizes from 1/2" to 1", this set is engineered for contractors and trades professionals who need to drill large diameter holes in low to medium tensile strength materials. A common flute and overall length across all bits minimizes adjustment time during tool changes, improving workflow efficiency on the job site. The set is equally suited for use with fixed spindle machines, making it a versatile addition to any metalworking or construction operation.

Technical Specifications

Available Items

Unlike standard jobber-length drill sets limited to smaller diameters, the 1000A series uses a 1/2" reduced shank to unlock large-diameter drilling capability from any standard 1/2" chuck — eliminating the need for a dedicated large-chuck machine. The black and bright surface treatment provides higher lubricity compared to an uncoated bright finish, reducing friction and heat buildup during cuts. The common flute and overall length across all 32 bits is a deliberate design choice that reduces setup time when switching between sizes mid-job.

Key Features & Benefits

1/2" Reduced Shank

The reduced shank design allows all bits in this set — including those up to 1" in diameter — to be used in any standard 1/2" drill chuck. This eliminates the need for specialized equipment to drill large diameter holes, making the set highly practical for contractors working with portable drills on site.

Premium Grade HSS Construction

Each bit is manufactured from premium grade high speed steel, providing the durability and wear resistance needed for repeated use in metalworking applications. HSS is the most commonly used tool material for general purpose drilling and is suitable for low to medium strength steels, aluminum, and other non-ferrous materials.

118° General Purpose Point Angle

The 118° conventional point is optimized for mild steels and free machining materials, making it the right geometry for the low to medium tensile strength applications this set targets. This point angle is a proven, widely applicable geometry that performs reliably across a broad range of common drilling tasks.

Black and Bright Surface Treatment

The black and bright surface treatment increases lubricity at the cutting interface, reducing friction and heat generation during drilling. Lower heat at the cutting edge helps extend tool life and maintain cutting performance over the life of the set.

Common Flute and Overall Length

All 32 bits share a common flute and overall length, which minimizes the need to readjust depth stops or machine settings when changing between bit sizes. For contractors running production work or making multiple holes of varying diameters, this consistency translates directly into faster cycle times and less downtime.

Stand-Mounted Set Organization

The 32-piece set is housed in a stand configuration, keeping all bits organized, accessible, and protected when not in use. Quick identification and retrieval of the correct size reduces time spent searching for the right bit on a busy job site.

Common Applications

Drilling Large Diameter Holes

The S&D design with 1/2" reduced shank enables drilling of holes from 1/2" up to 1" in diameter using a standard portable drill, covering large-diameter requirements without specialized equipment.

Low to Medium Tensile Strength Materials

The 118° HSS configuration is optimized for drilling into low and medium tensile strength materials, including mild steels and free machining metals commonly encountered in construction and fabrication work.

Fixed Spindle Machine Operations

The set is well suited for use in drill presses and other fixed spindle machines where consistent hole geometry and repeatable depth are required across multiple workpieces.

Multi-Size Production Drilling

The common flute and overall length across all 32 bits makes this set particularly efficient for production scenarios where operators need to switch between multiple hole sizes with minimal machine adjustment.

Safety Data Summary

Hazard Information

• During normal operation, 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 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 possibly cancer of nasal passages and lungs.
• Tungsten (present 5–10% by weight): some evidence of pulmonary involvement such as cough.
• Vanadium (present 0–5% by weight): eye and respiratory tract irritant.
• Cobalt dust is reported as 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.
• 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

• All grinding, cutting, and machining operations should be performed in well-ventilated areas; use local exhaust ventilation adequate to limit personal exposure to airborne dust below PEL or TLV levels.
• 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 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.
• For powder fires: smother with dry sand, dry dolomite, ABC type fire extinguisher, or flood with water.

Frequently Asked Questions

Q: What chuck size is required to use these drill bits?
