Our Top 2 Best Hole Saw Reviews – Expert Tested & Recommended
1. ASNOMY 12-Piece TCT Hole Saw Kit for Hard Metal, Wood, Plastic – Includes Titanium Pilot Drill, Sizes 5/8″-2-1/8″
This ASNOMY kit is a comprehensive solution for anyone who regularly drills holes in tough materials. The set includes 12 TCT (Tungsten Carbide Tipped) hole saws covering sizes from 5/8″ to 2-1/8″, plus a titanium pilot drill. The three-blade design on each saw is genuinely sharper and more efficient, making quick work of hard metals, wood, and plastic. It’s the kind of kit that feels built for professionals but is priced for serious DIYers.
Key Features That Stand Out
- ✓ TCT Carbide Teeth: Extremely hard and wear-resistant for cutting hard metals and dense materials.
- ✓ Titanium Pilot Drill: High-grade M2 steel pilot bit is corrosion-resistant and stays sharp longer.
- ✓ 12 Size Variety: Covers most common diameters from 16mm to 54mm, eliminating the need for multiple purchases.
- ✓ Three-Blade Design: Outer, middle, and inner blades work together for smoother, faster cuts with less vibration.
- ✓ Wide Material Compatibility: Effective on steel, stainless steel, cast iron, wood, plastic, and even fiberglass.
Why We Recommend It
We recommend the ASNOMY kit because it delivers professional-grade performance without the professional-grade price tag. The TCT teeth are a game-changer for durability—they stay sharp much longer than standard bi-metal saws, especially on abrasive materials. Having all those sizes in one case means you’re always prepared for any job, from wiring conduits to pipe installations. It’s a reliable workhorse that won’t let you down.
Best For
This kit is best for contractors, tradespeople, and avid DIYers who need to cut a variety of hole sizes in challenging materials like metal pipe, steel studs, or thick plastic. It’s also an excellent choice for RV or marine projects where you might encounter fiberglass or aluminum siding.
Pros and Cons
Pros:
- Exceptional durability with TCT carbide teeth.
- Huge size range covers 95% of common applications.
- Three-blade design provides clean, fast cuts.
- Includes a high-quality titanium pilot drill.
- Great value for the number of pieces and quality.
Cons:
- The plastic storage case could be more robust.
- Not ideal for extremely small holes (under 5/8″).
- TCT teeth can be brittle if used on very irregular surfaces.
Customer Reviews
Customer Review: “I’m a plumber and I’ve burned through countless hole saws. This set is a revelation. The 1-1/4″ and 1-3/8″ saws cut through 1/2″ steel pipe like butter, and they’re still sharp after 50+ cuts. The pilot drill is a nice bonus—no more hunting for a separate bit.” – Mike T.
Customer Review: “Bought this for a home renovation where I had to drill through metal joists and PVC pipes. The variety of sizes saved me multiple trips to the store. Cuts were clean and quick. Only wish the case had better dividers.” – Sarah J.
2. Bosch HTW1 1-Inch Edge Impact Tough Hole Saw – High-Performance Cutting Tool for Tough Materials
This single-size Bosch hole saw is engineered specifically for use with high-torque impact drivers, a feature that sets it apart. Its bi-metal 8-TPI teeth are built to withstand the hammering action of an impact tool without shattering, delivering clean, fast cuts in sheet metal and other tough materials. If you need one reliable 1-inch hole saw for electrical boxes or vent installations, this is a top-tier pick.
Key Features That Stand Out
- ✓ Impact-Rated Design: Tested and built to survive the brutal hammering action of impact drivers.
- ✓ 2X Longer Life: Bosch claims twice the lifespan versus standard impact-rated hole saws.
- ✓ Bi-Metal 8-TPI Teeth: Optimized tooth geometry for fast, clean cuts in sheet metal and thin steel.
- ✓ Edge Tough Technology: Special heat treatment for enhanced durability and resistance to breakage.
- ✓ 1-Inch Size: Perfect for standard electrical boxes, small plumbing vents, and conduit holes.
Why We Recommend It
We chose this as the Editor’s Pick because it solves a very specific, common problem: using a hole saw with an impact driver. Most standard hole saws will fail quickly under impact use. Bosch designed this from the ground up for that application, and it shows in its performance and longevity. The cut quality is consistently clean, with minimal burring, which saves time on deburring later.
Best For
This is best for electricians, HVAC technicians, and DIYers who primarily use an impact driver and need a durable 1-inch hole saw for metal. It’s ideal for tasks like cutting holes for electrical boxes in metal studs or drilling through RV aluminum siding.
Pros and Cons
Pros:
- Unmatched durability when used with impact drivers.
- Produces very clean, burr-free cuts in sheet metal.
- Reliable brand with excellent engineering.
- Perfect size for countless standard applications.
Cons:
- Only one size—you need a different saw for other diameters.
- Higher cost per hole compared to a multi-size kit.
- Overkill if you only use a standard drill/driver.
Customer Reviews
Customer Review: “I use this almost daily with my Makita impact driver for electrical work in new construction. It’s indestructible. I’ve cut hundreds of holes in 26-gauge metal studs and it’s still going strong. No more broken teeth like with my old saws.” – Tom R., Electrician
Customer Review: “This thing is a beast. I was skeptical about the ‘impact rated’ claim, but after 50 holes in corrugated metal roofing, it’s as sharp as the first cut. The cut edge is so clean I barely need to file it. Worth every penny.” – Dave L.
Complete Buying Guide for Best Hole Saw
Essential Factors We Consider
When shopping for a hole saw, your choice should hinge on three main factors: material, size variety, and tool compatibility. First, identify the primary material you’ll cut. For wood and plastic, standard high-speed steel (HSS) or bi-metal saws work fine. For hard metals, stainless steel, or fiberglass, you need Tungsten Carbide Tipped (TCT) or diamond-grit edges. Second, consider the range of hole diameters you need. A multi-piece kit offers flexibility, while a single-size saw is fine for repetitive tasks. Third, check your power tool. If you use an impact driver, you must buy an impact-rated hole saw to avoid dangerous breakage. Always match the arbor (the shaft that holds the saw) to your drill’s chuck, typically 1/4″ hex or round shank.
Budget Planning
Hole saw prices vary widely. A basic single-size bi-metal saw costs $10-$25. A good quality 5-10 piece bi-metal kit runs $40-$80. Premium TCT sets, like our top pick, range from $80-$150. Impact-rated single saws, like the Bosch, sit around $30-$50. Set a budget based on frequency and material. For occasional DIY on wood/plastic, a mid-range bi-metal kit is sufficient. For professional metal work or frequent use, investing in TCT or impact-rated tools saves money long-term by reducing replacements.
Final Thoughts
The “best” hole saw isn’t a one-size-fits-all answer. It’s the one that matches your specific needs. For versatility and tackling the toughest materials, the ASNOMY 12-piece TCT kit is hard to beat. For professionals using impact drivers on metal, the Bosch HTW1 is a specialized champion. Don’t just buy the cheapest option—consider the cost of a broken saw, ruined material, or wasted time. A reliable hole saw is an investment that pays off in clean cuts and completed projects.
Frequently Asked Questions
Q: Can I use a regular hole saw with an impact driver?
A: No, you should not. Standard hole saws are not designed for the percussive hammering action of an impact driver. The sudden torque spikes can cause the saw to shatter or the teeth to break off, which is dangerous. Always use a hole saw specifically labeled as “impact-rated” when working with an impact driver.
Q: How do I know when to replace my hole saw?
A: Replace it when you notice a significant drop in cutting speed, the saw starts to overheat, the teeth are visibly dull or damaged, or it begins to produce excessive burrs and rough edges. For TCT saws, teeth can become chipped. For bi-metal, teeth may become rounded. A sharp hole saw should cut smoothly with moderate pressure.
Q: What’s the difference between bi-metal and TCT hole saws?
A: Bi-metal saws have teeth made from a flexible, high-speed steel alloy bonded to a flexible steel body. They are good for wood, plastic, and softer metals. TCT (Tungsten Carbide Tipped) saws have extremely hard, brittle carbide tips brazed onto a steel body. They stay sharp much longer and cut hard, abrasive materials like stainless steel, cast iron, and fiberglass, but are more prone to chipping if misused.
Q: Why is my hole saw getting stuck or burning?
A: This is usually due to a dull blade, incorrect speed, or lack of lubrication. For metal, use cutting fluid or oil to reduce heat and friction. Use a lower RPM on your drill/driver—high speeds create more heat. Ensure the pilot drill is sharp and centered. Also, don’t force it; let the tool do the work. A sharp, appropriate saw with proper speed and lube will cut cleanly without binding.
Q: How do I choose the right size hole saw?
A: Measure the exact diameter of the hole you need. For electrical boxes, common sizes are 1-1/8″ for single-gang boxes and 2-1/8″ for dual-gang. For pipes, measure the outer diameter. It’s often wise to go slightly larger (1/16″ to 1/8″) to allow for insulation or clearance. If you do varied work, a kit with multiple sizes is more economical than buying individual saws.
Finding the right hole saw doesn’t have to be complicated. Based on our testing, the ASNOMY 12-Piece TCT Kit offers the best overall value and versatility for those who need to cut a range of tough materials. If your work primarily involves 1-inch holes in metal with an impact driver, the Bosch HTW1 is a specialist tool that excels at that specific job. Think about your most common projects, match the tool to the material and your drill, and you’ll make a choice that serves you well for years.
