9500CT Carbide Tipped Hole Cutter Set

DRILLCO 9500CT Carbide Tipped Hole Cutter Set — 6-Piece TCT Set for Thin Material Up to 3/16"

The DRILLCO 9500CT Carbide Tipped Hole Cutter Set is a 6-piece tungsten carbide tipped (TCT) hole cutter kit designed for drilling large diameter holes in both ferrous and non-ferrous materials up to 3/16" thick. Built for portability, the set is compatible with standard portable hand drills via a 3-flats shank and is suited for electricians, plumbers, HVAC technicians, mechanics, general contractors, and installers. The 9500CT is a cost-effective, high-performance alternative to bi-metal hole saws, capable of cutting through materials ranging from plastic to stainless steel.

Spare Parts

Unlike bi-metal hole saws, the 9500CT uses premium grade tungsten carbide teeth that deliver increased performance and longer tool life across a wider range of materials, including difficult-to-machine stainless steel. The single body design reduces vibration compared to multi-piece assemblies, and the spring-loaded pilot drill simplifies slug removal without additional tools.

Key Features & Benefits

Ultra-Hard Tungsten Carbide Teeth

The cutters are tipped with premium grade tungsten carbide, providing significantly greater hardness than bi-metal alternatives. This translates to longer tool life and consistent cutting performance across a broad range of materials, from plastics to stainless steel.

3-Flats Shank for Portable Hand Drills

The 3-flats shank design is compatible with standard portable hand drills, making the set practical for field use without requiring a magnetic drill press or stationary equipment. This portability makes the set suitable for electricians, plumbers, HVAC technicians, and general contractors working on-site.

Spring-Loaded Pilot Drill for Easy Slug Removal

The integrated spring-loaded pilot drill automatically ejects the slug after each cut, eliminating the need to manually remove material from the cutter. This speeds up repetitive hole-making tasks and reduces downtime between cuts.

Single Body Design for Reduced Vibration

The one-piece body construction minimizes vibration during cutting compared to multi-component designs. Reduced vibration improves cut accuracy and operator comfort during extended use.

Cost-Effective Alternative to Bi-Metal Hole Saws

The 9500CT is positioned as a high-performance, cost-effective replacement for bi-metal hole saws. Contractors can achieve better tool life and cutting performance without the higher cost typically associated with carbide tooling.

Common Applications

Electrical Work

Ideal for drilling large diameter holes through electrical panels, junction boxes, and thin sheet metal enclosures up to 3/16" thick.

Plumbing

Used to cut clean, accurate holes in thin sheet materials for pipe penetrations and fitting installations.

HVAC Installation

Suited for cutting holes in ductwork, sheet metal panels, and other thin ferrous and non-ferrous materials encountered in HVAC applications.

Drilling in Thin Sheet Metal

Designed specifically for thin sheet applications up to 3/16" depth of cut, including steel, aluminum, copper, and brass sheet stock.

Drilling in Plastics and Non-Ferrous Materials

The carbide teeth handle materials ranging from plastic to stainless steel, making the set versatile for mixed-material jobsite conditions.

Safety Data Summary

Hazard Information

• NFPA Health Rating: 3; Flammability: 0; Reactivity: 0
• Cobalt is listed as IARC Group 2B (possibly carcinogenic to humans)
• Grinding or dust generation may produce hazardous airborne particles that can be inhaled, swallowed, or contact skin and eyes
• Inhalation of dust may cause irritation of the nose and throat; potential for occupational asthma and interstitial fibrosis with prolonged exposure
• Skin contact may cause irritation or allergic rash due to cobalt sensitization
• Eye contact may cause irritation
• California Proposition 65 Warning: This product can expose you to chemicals including Cobalt, which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov
• Incompatible with strong acids and strong oxidizers
• Not combustible, not flammable, not pyrophoric, not explosive in solid form

Personal Protective Equipment

• Wear safety glasses or goggles with side shields; do not wear contact lenses when handling
• Cloth or leather gloves 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

Safe Handling

• Use local exhaust ventilation adequate to limit personal exposure to airborne dust below PEL or TLV levels
• Clean up using methods that avoid dust generation: vacuum with appropriate filters, wet dust mop, or wet clean-up
• 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
• Store in a dry place; store in a manner that prevents accidental environmental contamination from traces of industrial lubricants or wetting oils
• Soiled clothing should be laundered separately
• Dispose of waste material in compliance with federal, state/provincial, and local environmental regulations; send to an appropriate reclamation facility if available
