Lenox Tools Hole Saw, Bi-Metal, 2-1/8-Inch
Brand: Lenox
Features: 2X more durable with 50% longer life than previous Lenox hole saws; increased wall thickness reduces tooth loss; optimized tooth design penetrates metal with ease.
Best for: Professionals and serious hobbyists who need longer tool life and reliable metal cutting. Lenox is chosen for repeated use in metal fabrication and electrical conduit work. Its bi-metal design balances durability with affordability.
Limitations: Durability claims rely on how the tool is used; ensure proper feed rate to maximize longevity. Some users may prefer carbide-tipped options for the toughest metals.
VIKITON 2-1/8 Inch Hole Saw for Wood, Metal, Plastic & Drywall
Brand: VIKITON
Features: Bi-metal construction with high-speed steel teeth and flexible steel body; lightweight with structural innovations that reduce weight; includes arbor, pilot drill, replacement bits, and hex key.
Best for: Users needing a versatile kit for metal, wood, plastic, and drywall with a compact setup and easy handling. The included arbor and pilot bits help beginners set up quickly.
Limitations: Not specifically optimized for ultra-hard metals; performance is strong on common metals but carbide-tipped options may outperform on very tough materials.
METOTY Metal Hole Saw 2-1/8” Set with Carbide Tipped Teeth
Brand: METOTY
Features: Two-piece set with carbide-tipped cutters; nitrided step drill and L-flange included; designed for steel, iron, aluminum, stainless steel, and plastic. Carbide tips boost hardness and rust resistance.
Best for: Projects involving hard metals where extended tool life is critical, such as stainless steel and thick sheet metal cutting. This set is suitable for magnetic or bench drills and offers high durability for repeated use.
Limitations: Not suitable for concrete, tiles, or stone; carbide tips add cost and may require careful handling to avoid chipping on misfeeds.
SALI 2-1/8″ TCT Hole Saw Kit
Brand: SALI
Features: Tungsten carbide tipped cutters with titanium-plated teeth; three-blade design for sharper, more efficient cutting; cutting diameter 2-1/8″ with 1-inch depth and 3/10″ shank. Suitable for hard metals.
Best for: Users needing fast, precise cuts in hard metals like stainless steel and iron, with a design that promotes efficient material removal. Good for electrical and mechanical panel work where clean openings are essential.
Limitations: Three-blade design improves cutting efficiency but may require careful alignment to avoid wandering on thin sheets.
Kolvoii 1-3/8″ TCT Hole Saws for Stainless Steel and Metal
Brand: Kolvoii
Features: Precision metal cutting with 1-3/8″ diameter; carbide tips provide hard cutting edge for stainless steel and other metals; three-blade control helps distribute cutting contact for steadier starts and cleaner openings.
Best for: Electrical and mechanical work requiring exact small openings in metal panels, especially when stainless steel is involved. Good for conduit hubs and service openings where precision matters.
Limitations: Slightly smaller diameter than the 2-1/8″ options; may require you to switch tools if you specifically need a 2-1/8″ cut.
Buying Guide
- What metal will you cut most often? For thick steel or stainless, carbide-tipped or carbide-heavy bi-metal options offer longer life and sharper edges.
- Is user comfort a priority? Bi-metal and tri-blade designs can reduce vibration and wandering, making them better for beginners and long projects.
- Do you need versatility? Kits with arbors, pilot bits, and multiple blades give flexibility across wood, plastic, and metal, but may be overkill if you only cut metal.
- How important is tool life? Carbide-tipped saws generally outlast standard bi-metal models in hard metals, but come at a higher price per piece.
- What is your drilling setup? Ensure your drill and bit shank size match the hole saw kit and arbor included for safe operation.
- What about cut quality? Look for optimized tooth design and proper depth control to minimize burrs and ensure clean holes in metal panels.

FAQ
- What is the typical use for a 2-1/8″ metal hole saw?
Answer: It’s commonly used for conduit openings, electrical panels, and metalworking openings where a precise 2-1/8″ diameter is required. - Which material improves durability the most?
Answer: Carbide-tipped or carbide-enhanced bi-metal designs generally offer the best wear resistance on hard metals like stainless steel. - When should I use a kit with an arbor and pilot bits?
Answer: If you cut metal frequently or need quick setup, a kit with an arbor and pilot bits reduces setup time and keeps cuts centered. - Are there any cautions with carbide hole saws?
Answer: Carbide tips are harder but can chip if fed too aggressively or used on very hard surfaces without proper backing. - Do hole saws require lubrication?
Answer: Light lubrication on tough metals can reduce heat and extend blade life, but follow manufacturer guidance for each tool.
