9500CT Carbide Tipped Hole Cutter, 3/16" Depth of Cut – Pack of 5

DRILLCO 9500CT Carbide Tipped Hole Cutter — Cost-Effective Large-Diameter Holes in Ferrous and Non-Ferrous Metals

The DRILLCO 9500CT is a carbide tipped hole cutter engineered for drilling large-diameter holes in both ferrous and non-ferrous metals. Designed for thinner material up to 3/16" thick, it is well-suited for electricians, plumbers, HVAC technicians, mechanics, general contractors, and installers who require a portable, high-performance hole cutting solution. Available in diameters from 9/16" to 4", the 9500CT delivers an excellent performing, cost-effective alternative to bi-metal hole saws across a wide range of jobsite applications.

Technical Specifications

Available Sizes

Sets & Spare Parts

The 9500CT stands apart from bi-metal hole saws by using ultra-hard tungsten carbide teeth made from premium grade carbide, delivering increased performance and tool life on both ferrous and non-ferrous materials. Its portability makes it a practical choice across multiple trades, and the broad size range from 9/16" to 4" means a single product line can cover the majority of large-diameter hole cutting requirements on a jobsite. For applications requiring deeper cuts in thicker material (up to 1"), DRILLCO's companion 9600CT model is available.

Key Features & Benefits

Premium Grade Tungsten Carbide Teeth

The ultra-hard tungsten carbide cutting teeth are manufactured from premium grade carbide, providing increased performance and extended tool life compared to standard bi-metal alternatives. For contractors cutting multiple holes per day, longer tool life translates directly to lower cost per hole and less downtime for tool changes.

Cost-Effective Alternative to Bi-Metal Hole Saws

The 9500CT is positioned as an excellent performing, cost-effective alternative to bi-metal hole saws. Trades professionals can achieve high-quality large-diameter holes without the premium price typically associated with carbide tooling.

Wide Diameter Range

Available in sizes from 9/16" to 4" in 1/16" increments across most of the range, the 9500CT covers virtually every large-diameter hole cutting requirement in thin material. This breadth of selection allows contractors to standardize on a single cutter platform across multiple applications.

Portable Design for Field Use

The portability of the 9500CT makes it ideal for a wide range of professionals including electricians, plumbers, HVAC technicians, mechanics, and general contractors working in the field. The tool is designed to be used where the work is, not just in a fixed shop environment.

6-Piece Set Available with Pilot Drills

The 9500CT is available as a 6-piece set (EDP No. 95CT6S) including 9/16", 5/8", 11/16", 3/4", 7/8", and 1-1/16" cutters plus two pilot drills, providing a ready-to-use kit for common hole sizes. Individual spare parts — including the HSS pilot drill, M6 screw, spring, and Allen wrench — are also available separately to minimize downtime.

Common Applications

Electrical Conduit and Panel Work

Electricians can use the 9500CT to cut precise large-diameter holes in thin metal enclosures, panels, and conduit plates where clean, accurate openings are required.

Plumbing Penetrations

Plumbers cutting through thin ferrous or non-ferrous sheet metal for pipe penetrations benefit from the cutter's ability to produce clean, burr-minimized holes in a single pass.

HVAC Ductwork and Equipment

HVAC technicians can cut large-diameter holes in thin sheet metal ductwork and equipment housings, where the 9500CT's 3/16" depth of cut is well matched to typical duct material thickness.

General Sheet Metal Fabrication

Mechanics and general contractors working with thin ferrous and non-ferrous sheet metal can use the 9500CT for a wide variety of hole-cutting tasks across steel, aluminum, copper, brass, and similar materials.

Safety Data Summary

Hazard Information

• Primary route of entry: inhalation, skin contact, eye contact, and ingestion of dust generated during grinding
• Inhalation of grinding dust may cause irritation of the nose and throat; potential for transient or permanent respiratory disease including occupational asthma and interstitial fibrosis
• Cobalt dust is identified as the most probable cause of respiratory disease associated with this product
• Skin contact can cause irritation or allergic skin rash due to cobalt sensitization
• Eye contact may cause irritation
• NFPA Health Rating: 3; Flammability: 0; Reactivity: 0
• Cobalt is listed as IARC Group 2B (possibly carcinogenic to humans)
• 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
• Persons with pre-existing respiratory disease may be at increased risk from exposure
• Product is not combustible, not flammable, not pyrophoric, and not explosive in solid form
• Incompatible with strong acids and strong oxidizers

Personal Protective Equipment

• Gloves: Cloth or leather gloves recommended when contact with dust or mist is likely
• Eye protection: Safety glasses or goggles with side shields; contact lenses should not be worn when handling these materials; employer should provide an eye wash station within the immediate work area
• Respiratory protection: 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 safety glasses and protective clothing to prevent injury in the event of tool breakage
• Soiled clothing should be laundered separately

Safe Handling

• Use local exhaust ventilation adequate to limit personal exposure to airborne dust to levels that do not exceed the PEL or TLV
• Operations such as welding, dust generation, or fume generation can result in hazardous exposure; protect against dust and fume inhalation and skin or eye contact
• Clean up using methods to avoid dust generation such as vacuum (with appropriate filters), wet dust mop, or wet clean up
• Do not shake clothing, rags, or other items to remove dust; remove dust by washing or vacuuming with appropriate filters
• Wash hands thoroughly after handling and before eating or smoking; wash exposed skin at the end of the work shift
• Store in a dry place; store in a manner that prevents accidental environmental contamination from traces of industrial lubricants or wetting oils
• Dispose of waste material in compliance with federal, state/provincial, and local environmental regulations; send to an appropriate reclamation facility if available
