Lenox Hole Saw 21 L To 1-5/16 in.
Features emphasize added durability, unique tooth configuration, and greater precision. This Lenox option is best for: professionals needing reliable, repeatable cuts in metal and automotive components, and hobbyists who prioritize clean holes with less wandering. The main limitation is that performance can vary with softer materials where a metal-specific saw isn’t required. Choose this if you value a proven, mass-market metal-cutting performanace with a focus on precision and long life.
1-5/16″ 33mm Bi-Metal Hole Cutter (CoCud)
Best for thick metal materials, including stainless steel, high carbon steel, cast iron, copper, and aluminum. The CoCud cutter uses a CVD-coated bi-metal design for high hardness and good self-lubrication. It is well-suited for automotive and boating projects where precise, reinforced holes are needed. It is not recommended for plastics or wood. The shank and cutting depth balance portability with cutting power, but users should avoid materials outside its intended metal-focused scope.
METALLIXITY Bi-Metal Hole Saw 33mm (M42)
Designed for hard metal applications, this M42 high-speed steel bi-metal saw includes 8% cobalt and a tri-shank with nitriding and paint coating for wear resistance. It’s best for thick stainless steel sheets and heavy metal drilling. The product is robust for professional metalworking but may be less optimized for wood or soft plastics. Best for: users needing longer life and higher heat resistance on tougher metals. Limitation: not ideal for non-metal materials.
SALI 1-5/16″ TCT Hole Saw Kit
Best for hard metals, with a tungsten carbide tipped tooth design and titanium-plated pilot. This kit features a three-blade arrangement, including outer, middle, and inner blades for sharper, more efficient cuts. It suits metalworkers and fabricators dealing with stainless, iron, and other tough materials. A caution: TCT tools can wear quickly if used on soft woods or plastics. Choose this when maximum hardness and speed are required for demanding metal projects.
Mollom 34mm HSS M42 Bi-Metal Hole Saw
Best for thick wood, metal, and multiple materials, this Mollom option uses M42 cobalt steel with a larger 34mm diameter. It includes two pilot drill bits and offers compatibility with various drills. It’s advantageous for builders and DIY enthusiasts who need a versatile tool for a range of materials. The caution is that metal-focused use is recommended to maximize lifespan; using it extensively on soft plastics or drywall may wear bits faster than intended.
Buying Guide: How to Choose a 1-5/16 Hole Saw
- Material compatibility: If cutting hard metals (stainless steel, cast iron), favor cobalt/M42 bi-metal or TCT-tipped designs. For wood or plastic, choose a standard bi-metal or wood-specific options.
- Tooth design and coating: TCT tips excel on hard metals; CVD coatings reduce heat buildup and increase wear resistance on metal sheets; conventional bi-metal works well for general use.
- Cutting depth and shank: Ensure the cutting depth accommodates your required hole size and that the shank diameter fits your drill chuck. A longer overall length can help with deeper cuts.
- Pilot bits: Some sets include pilot bits; if not, confirm compatibility with your drill and pilot size to ensure clean centers and straight holes.
- Drill compatibility: Use with appropriate drill speed settings and avoid soft materials that may not benefit from high-hardness cutters.

Frequently Asked Questions
- What is the difference between bi-metal and TCT hole saws? Bi-metal is durable for a range of metals; TCT (tungsten carbide tipped) is sharper and better for hard metals but can be costlier and wear differently.
- Can I use these hole saws on wood? Some are suitable for wood, but heavy metal-focused designs may perform poorly or wear faster when used on wood.
- Do hole saws require a pilot drill bit? Many sets include a pilot; if not, a center drill bit is essential for accuracy.
- What safety considerations exist for metal drilling? Wear eye protection, clamp workpieces, and avoid overheating the bit by using appropriate drilling speeds and lubrication when needed.
- Are these universal fits for standard drills? Most are designed to fit standard drill chucks, but verify shank size (often 7.5 mm or 3/8 inch) before purchase.
- How to maintain hole saws for longevity? Clear chips frequently, avoid forcing the cut, and use proper lubrication in metal Cutting.
