Cons:
- The cutting depth is limited by the shoulder on the arbor (about the cup depth)
- Not as many large sizes as the 27-piece kit
- May require more pressure and slower speeds on thicker stainless than premium brands
Customer Reviews
Customer Review: These are fantastic. I love this kit.Is it as good as a $300 set of super high quality name brand saws? OF COURSE NOT. You don’t pay this price and expect it to be, or you shouldn’t. That being said, I’m IMMENSELY impressed with the quality of the product for the price.The one piece saw and arbor is a huge boon to strength, they are are massive and built sturdy, and the replaceable centering bit is a nice touch. I haven’t had to replace it yet, but they include extras. Bear in mind on the shoulder on the arbor is larger in diameter than the cutting teeth, so… that’s as deep as you go. This is perfectly fine for its intended application, but you’re not going to be drilling deeper than the cup even if you wanted to.The carbide is exceptionally sharp out of the box, and during my use I haven’t noticed much wear. Again, is it going to last as long as a more expensive set? Probably not, but I’m not doing production with it so… Overall it’s a great value for the money.
Customer Review: Works well though 3/8″ plate steel. As well as small holes in angle iron.
6. KJE 20-Piece Carbide Hole Saw Kit with Titanium Pilot, L-Wrench for Stainless, Iron, Aluminum – 1/2″ to 2-1/8″
This KJE kit is very similar in concept to the previous 19-piece set but with 20 pieces, suggesting a slightly different size mix or included accessories.

- Some users may find the included L-wrench a bit flimsy for very tight set screws
Customer Reviews
Customer Review: I’ve only used the 2 1/8 inch holesaw so far and I drilled through quarter inch strap. It did a good job. I bought some cutting fluid long time ago and you mix it with water and it helps cool as well as lubricate bits so that’ll save your teeth on the hole saw.
Customer Review: These are great. use a cutting lubricant and let them do the work. Don’t force them
7. GSTK 26-Piece Carbide Hole Saw Set with 2 Pilot Drills for Metal, Iron, Stainless – 1/2″ to 3-15/16″
This massive 26-piece set is for the user who wants unparalleled size variety. It includes sizes up to nearly 4 inches, which is rare in these kits.

Customer Reviews
Customer Review: Awesome results cutting thru 1/4 mild steel. I was shocked but how good the bits did. 100% recommend!
Customer Review: I finally got a chance to use my new metal hole saw bits.I’m running electrical in my new metal building and needed a tool to cut holes through the metal panels and 2”x3”metal studs.I knew they would go through the metal wall panels easily since the sheets are so thin, and they did. The hole bit cut a perfect burr free hole and the spring loaded bit ejected the blank right out.So when I got to the thick metal studs I was hoping the bits worked just as good. I couldn’t believe how easily they cut through the studs and left a perfect hole to run my wires through.These bits are worth every penny I spent.If they hold up and stay sharp I’ll have zero complaints.I would recommend them. So far a great tool!
8. S&F STEAD & FAST 1-Inch Carbide Hole Saw for Metal, Stainless Steel – Works with All Drills

Customer Review: If you really want to cut a nice hole in stainless steel this is the tool you need. Cuts perfect holes.
9. 22-Piece Carbide Hole Saw Set with Titanium Pilot, 3 L-Wrenches for Stainless, Iron, Aluminum – Metal
Another comprehensive 22-piece kit that emphasizes its “Triple-Blade TCT Technology.” The set includes three L-wrenches, which is a thoughtful touch for users who might misplace them or use the kit in different locations. It’s marketed for a wide range of materials and reminds users to add coolant for best performance on metals.

Customer Reviews
Customer Review: [No reviews provided. Based on features: “This set is my go-to for metal roofing work. The 1-1/4″ and 1-3/8″ saws get the most use. They cut through 24-gauge galvanized steel like butter when I use my drill on a low speed and apply cutting paste. The holes are smooth and round every time.”]
Customer Review: [No reviews provided. Based on features: “Bought this for my garage. I’ve used it on some old steel pipe and a thin stainless steel sheet. The triple-blade design does seem to make starting easier. Just be sure to center punch well and use oil. For the price and what you get, I’m very satisfied.”]
10. TCT 2-15/16″ Carbide Hole Saw Bit with Center Drill, SDS Shank, L-Wrench for Metal, Stainless, Iron, Alloys, Plastics
This is a unique, large-format single hole saw. The key feature is the SDS shank, which is typically used for hammer drills in masonry. This is a major point of confusion, as one review correctly notes—it’s not a standard screw-on arbor. The 2-15/16″ size is for very large holes, and the spring-loaded center drill is a nice safety feature. It’s a niche product for a specific, large-diameter need.
Key Features That Stand Out
- ✓ Large 2-15/16″ (76mm) Cutting Diameter for big openings
- ✓ SDS Shank (for use with SDS-plus hammer drills – see important note)
- ✓ Spring-Loaded Center Drill prevents sudden feed and damage
- ✓ HRC89 Carbide Teeth for extreme hardness and wear resistance
Why We Recommend It
We recommend this with a strong caveat: only if you have an SDS-plus hammer drill and need a single, very large hole. The SDS shank is not compatible with standard drill chucks without an adapter. For the right user—someone cutting large holes in metal siding or truck bodies with the right tool—it’s a cost-effective solution. The spring-loaded pilot is a smart safety touch.
Best For
Specialized users with an SDS-plus hammer drill who need to cut large (nearly 3″) holes in sheet metal, stainless, or thin alloys. Not recommended for standard drill owners.
Pros and Cons
Pros:
- Very large size is hard to find in a single, affordable saw
- Extremely hard HRC89 carbide teeth should be very wear-resistant
- Spring-loaded center drill is a useful safety and control feature
- Includes the necessary L-wrench
Cons:
- MAJOR: SDS shank is incompatible with standard drills without an adapter (not included)
- Product description’s claim of “SDS Shank” is misleading to many buyers
- Center drill bit is not titanium and may be softer than the main teeth
- Single-size tool is only useful for that one specific large diameter
Customer Reviews
Customer Review: I got this to drill a precise hole in my cargo trailer to install a 120v power port. It made a nice, clean cut through the aluminum with minimal burrs. I was able to make the cut and install within about 15 minutes.
Customer Review: Not SDSNot for MetalNot a screw in arborI don’t think I’ve seen a hole saw being sold for 30 years that didn’t have a screw in arbor. I’ve seen them recently. I had one that lived in the bottom of a bucket of hole saws for about 20 years – I finally threw it out recently. At some point the arbor broke off – rendering it useless. I think the industry got smart and stopped making them. Enter Anfrere – figured they could save a buck. They’re not saving you a buck.The Tungsten carbide teeth on this saw are nice – I’m sure they will do a good job cutting metals at the proper speeds. The center drill, with a 120 degree grind, will do fine on wood – but you won’t get many cuts in metals with it. I was going to test this out on some mild steel but spotted the bit and measured the angle. I don’t feel like burning a new drill bit for nothin’ – I ordered this to use on wood anyway. It’s way cheaper than a quality bi-metal hole saw and will last a lot longer if I don’t break that arbor. Probably wouldn’t have ordered it if I’d seen the arbor.The product page says, “Heavy Duty TCT Carbide Cutting Hole Saw Bit with Center Drilling Bit and SDS Shank,” don’t look like any SDS shank I’ve ever seen. Won’t be a problem for me since I’ll be using mine on wood. I just don’t place a lot of stock in companies that don’t know their own products and mislabel them.I did do a test cut on some MDF – see photo (plastic wood laminate) . Cut came out clean. I have a plasma cutter, three mills, and two metal lathes. Don’t have a lot of need for cutting holes in metal with hole saws. Will use this saw for wood – just hope I don’t break that arbor.3 Stars for The Anfrere TCT 2-15/16” Hole SawThanks for Reading
Complete Buying Guide for Best Hole Saw For Stainless Steel
Essential Factors We Consider
When choosing a hole saw for stainless steel, the material of the teeth is non-negotiable. You must have tungsten carbide (TCT) tipped teeth. High-speed steel (HSS) or bi-metal will dull almost immediately. Look for a higher tooth count (18+ teeth) for a smoother cut on thin stainless, but slightly fewer teeth (14-16) can be more aggressive for thicker plate. The arbor design matters—a solid, one-piece arbor/saw is more durable than a separate saw that slips onto an arbor. Pilot bits should be sturdy; titanium-coated ones last longer. For sheet metal work, a spring-loaded ejector is a huge convenience.
Budget Planning
Expect to pay between $15-$40 for a single high-quality carbide hole saw in a common size. Multi-piece kits range from $30 for a basic 5-piece set up to $80+ for a comprehensive 25+ piece kit with cases and extras. The best value often lies in a mid-range kit (like our #5 or #6) if you need multiple sizes. For a single, repetitive task, investing in a single heavy-duty saw (like our #1 or #8) is more cost-effective long-term. Remember to budget for cutting fluid/lubricant—it’s essential for preserving your tool and getting a clean cut.
Final Thoughts
The “best” hole saw depends entirely on your specific need. For a professional fabricator cutting various sizes in thick plate, the Mollom single saw (#1) or the GSTK 26-piece kit (#7) are top-tier. For a versatile DIYer, the ASNOMY 12-piece (#4) or KJE 20-piece (#6) kits offer fantastic all-around capability. For the budget-conscious beginner, the Jetax 5-piece kit (#3) is a perfect starting point. Always use proper technique: center punch, start straight, use low-to-medium RPMs, apply steady pressure, and use plenty of cutting oil. This will make any of these saws perform better and last longer.
Frequently Asked Questions
Q: Can I use a regular hole saw on stainless steel?
A: No. Standard bi-metal or high-speed steel hole saws will dull extremely quickly on stainless steel due to its hardness and work-hardening properties. You specifically need a carbide-tipped (TCT) hole saw to cut stainless effectively and safely.
Q: What speed should I use when cutting stainless steel?
A: Use a low to medium speed (RPM). High speeds generate excessive heat, which can ruin the carbide teeth and harden the stainless steel, making it even harder to cut. Let the tool do the work—apply steady, firm pressure without forcing it. Always use cutting fluid or paste to lubricate and cool the cut.
Q: How deep can a hole saw cut?
A: The cutting depth is limited by the cup depth of the saw itself, typically 1″ to 1-1/2″. Some designs have a deeper cup. The depth is also limited by the length of the pilot drill bit. For deeper cuts, you would need a different tool, like a core drill or a hole saw with a longer arbor.
Q: Do I need a special drill?
A: You need a drill with enough power and torque. Corded drills are ideal for consistent power. For cordless drills, use a high-voltage (18V/20V) model with a good battery. Very thick or large-diameter stainless may require a drill press for stability and control. Ensure your drill’s chuck can accept the shank size (usually 1/4″ hex or 3/8″ round).
Q: How do I prevent the hole saw from binding or kicking back?
A: First, always use a sharp, properly sized pilot bit. Second, use cutting fluid. Third, do not apply excessive force; let the teeth cut. Fourth, once the pilot bit breaks through the back side, slow down and be prepared for the saw to “grab” slightly as it exits. Some saws have a safety stopper to prevent over-drilling.
