Best Hole Saw For Hardie Board: Top 10 for 2026 – Expert Tested

Customer Review: Works great for canless LEDs, for drywall, plaster/lath it’s amazing, this doesn’t wear out like a metal holesaw. I’ve cut over 50 holes in drywall, plaster/lath and wouldn’t know it by looking at the teeth of the holesaw. I’ve cut one hole thru natural stone tile, it was slow and used water to cool, but it worked. Will work on wood, but takes a little while. Im an electrician and have 3-5/5”, 4-1/8”, 4-1/4”, 6-1/4” and they are all great, the price is also great.

Customer Review: Awesome bit especially at the price point!! Arbor and 2 pilot bits included… GREAT DEAL!!

Customer Review: Worked fine for my project, though started getting dull after only a few holes through plywood. However pretty hefty build, size was just right, 6.25″ OD.

Customer Review: Worked well for my cornhole build. It’s been passed around at work several times and still cuts great.

Customer Review: Well made with good threads and fittings. It includes the wrench and is easy to change the pilot drill in the middle. I tested it on foam and worked just fine. Good value for the money.

Customer Review: I recently purchased the MOLLOM HSS M42 BI-Metal Hole Saw, and I must say, it’s an excellent product. The quality of this hole saw is top-notch, and it delivers smooth cutting results. I have used it to create three holes in wooden boards, and the cut surfaces have been remarkably smooth. One thing to note is that when using this hole saw, it’s important to start with a low rotational speed and maintain balance. Otherwise, there is a risk of the pilot bit breaking. I learned this the hard way, as I initially used a high speed that caused the pilot bit to snap. However, once I adjusted the speed and maintained a steady hand, the hole saw worked flawlessly. The MOLLOM HSS M42 BI-Metal Hole Saw is versatile and has been effective in cutting through various materials such as PVC, drywall, wood, plastic, gypsum board, and rubber. Its durability and sharpness have impressed me, as it has maintained its cutting performance even after multiple uses. The included mandrel adds convenience to the whole package, allowing for quick and easy assembly. The hole saw fits securely onto the mandrel, ensuring stability during cutting. Overall, I highly recommend the MOLLOM HSS M42 BI-Metal Hole Saw to anyone in need of a reliable cutting tool. Just remember to start with a low rotational speed, maintain balance, and you’ll achieve smooth and precise cuts every time.

Customer Review: If you’re looking to cut a hole, this will do it. I needed to cut a dryer vent hole through stucco and sheathing. It cut through relatively easy but I can’t say if you needed to cut 10 holes that this would last. It served its purpose for me one time and it’s most likely going to be the one time I need to cut through all that material.

Customer Review: Round electrical boxes fit perfectly in holes bored from this tool.

Customer Review: Used this to install an AC vent duct through drywall, foam, and stucco. Worked great with a clean cut, and almost no visible tool wear. Make sure to keep your tool speed at less than 100RPM with all carbide grit bits and they will last for a long time!

Customer Review: So far 8 holes through plaster over blue board. Pretty thick stuff. Cuts fast, shows no signs of wear.

Customer Review: Bought this hole saw to cut through plaster. It cut through the plaster better than expected, but did not cut through the wood lath. It is not designed to cut wood, but I was hoping. Cut 2 holes and it is still as sharp as when it came in. The saw comes with 2 centering concrete bits. The centering bit can be changed out. Great value for the money. Easy to use.

Customer Review: Performed very well! I run it for 15 holes through double stucco and metal mess, for spot lights and did well. My electrician was surprised that lasted for all these! Paid a bit more than others and the durability proved and justified the value

Customer Review: This 55 mm steel hole saw is a very specific tool, and it’s important to judge it on what it’s actually designed to do — not what people wish it would do. First, this is not a kit. It’s a single 55 mm hole saw that includes:* a pilot bit* an arbor (with spring ejector)* and an Allen wrench to swap the pilot if needed The product description clearly states its intent: thin metal, PVC, acrylic, plastic, and wood board. That matters because this tool is absolutely not designed for deep boring or thick stock. The cutting geometry makes that obvious. The teeth are very aggressive and forward-pointed, with a sharp leading point and a steep relief angle behind it. This is classic sheet-metal hole saw geometry, meant to bite quickly and evacuate material fast — not slowly chew through depth. Depth is the most commonly misunderstood aspect of this tool. The cutting cup is exactly 10 mm deep, measured from the base of the cup to the tips of the teeth. That’s intentional. For sheet metal, plastic panels, acrylic, and thin boards, you want shallow depth. Any thicker, and heat buildup becomes a serious problem. Complaints about “limited depth” are really complaints about using the wrong tool for the job. Speed control is critical with a hole saw like this. It requires very low RPM, especially in steel. Running too fast will generate excess heat and can discolor (blue) the teeth — not necessarily because the tool is bad, but because hole saws demand torque and slow speed to work correctly. This is not a good match for drill presses that can’t get slow enough or lack sufficient torque at low speed. At $9.99, this is very inexpensive for a steel hole saw of this size. Based on the tooth design and construction, it appears properly engineered for thin-material cutting — but it demands the right setup and expectations. Bottom Line: A specialized 55 mm hole saw designed for thin materials that does exactly what it’s meant to do — as long as you use it correctly. Pros & Cons ✅ Aggressive tooth geometry ideal for sheet metal and plastics ✅ Includes arbor, pilot bit, and wrench ✅ Shallow 10 mm depth is intentional and appropriate ✅ Very affordable for its size ✘ Not suitable for thick material or deep boring ✘ Requires very low RPM and good torque to avoid overheating If you need clean, fast holes in thin metal or panel materials, this tool makes sense. Just don’t ask it to be something it was never designed to be.

Customer Review: I have four 15/16″ fittings that I needed to place in some 12 gauge cor-ten steel. I wanted a tight fit. Had a chance to try out this 31/32″ hole saw. Using an 18 volt cordless drill on low torque, and some cutting oil, I made four holes. I went very slow – let the drill do the work without excess pressure. The holes came out clean. Did not take excessively long. I would say the 31/32 sizing is accurate. I did have to tap the fittings through – so could be the bit or I could have easily drilled at a slight angle. Happy with the results. There was wear on the bit, but I imagine I could drill many more holes.

Customer Review: The DTGN hole saw cut through various materials like plywood and pvc without any issues. The included center bit made it easy to guide and make accurate cuts. I ordered this to drill a hole into a custom made rainbarrel to add a spout, and I found this tool much easier to work with than a spade. For such a low price, I think it’s a great value and I’ll be able to use it for future projects as well since it came with a nice storage case.

Customer Review: This hole saw is a good addition in my woodshop. Assembly is simple. The center drill bit’s shank features a flattened section for the locking set screw to positively index on, eliminating annoying spin that can happen on round shanks. The high TPI produces clean cuts. However, high TPI means small gullets that fill with sawdust quickly requiring slower drill speeds. I found when used in plywood and soft pine debris would get easily compacted in the gullets if driven too hard. At less than $10, I found it to be a good value.

Customer Review: This bit worked pretty well. I probably started with an item that was too heavy a gauge, but it eventually worked- tip is to definitely do a starter hole- bit got very hot – again probably because my steel trivet was a heavy gauge- I like the fact that the starter bit is actually part of the overall bit unit, and the hex key for tightening- bit came in a nice clear container- good price value- I would expect this to work quite well on a thinner substrate

Customer Review: The 25/32″ 4241 HSS Hole Saw kit is excellent for precise drilling. I’ve used it on steel, aluminium, and plastic, and it cuts cleanly every time. The build feels solid and durable, making it ideal for DIY or professional projects. A reliable, high-quality addition to any toolkit.

Customer Review: This hole saw is excellent, and a great addition either as a standalone or as an addition to the Spyder hole saw kit. Just a couple things to note: It is NOT meant to cut through metal. I think this confuses many people, but you’ll want a more traditional bimetal hole saw with smaller teeth for metal. Be very careful not to drop this expensive tool it on concrete or other hard surfaces. Ask me how I know…

Customer Review: These Spyder 2-3/8″ carbide-tipped hole saws cut through fiber cement, wood, and PVC with ease, but the tips can jump around if you’re not careful. Steady hands and a pilot bit help keep everything precise. Quality carbide, sharp teeth, and strong construction make them a solid choice for tough materials — just take your time to avoid wandering cuts.
