10 Best Hole Saws For Metal in 2026

Ice Hardened construction offers up to 50% longer life than the competition, meaning these saws can drill significantly more holes in metal before dulling. The Matrix II bi-metal teeth and radiused tooth back are designed for greater durability and reduced stress, which helps prevent tooth breakage during demanding jobs. Features like a positive rake angle and deeper gullets promote fast cutting and chip removal, keeping the tool cooler and preventing jams. With 28 pieces, the set covers a wide spread of common sizes for versatile use in general purpose applications.

You are trading some specialization for that all-purpose durability. For example, if your work is exclusively cutting through stainless steel or cast iron with embedded fasteners, the Diablo Carbide Teeth set might offer even more longevity in those extreme scenarios. This Milwaukee kit, however, provides a great balance of long life in general metal applications, smart design for chip and plug removal, and a strong warranty. It’s a premium set that justifies its cost through performance and reduced replacement frequency.

A 13-piece kit with two arbors is the core of this set. Having a spare arbor means one can be left set with a frequently used hole saw, reducing downtime to swap components in tight spaces. Bi-metal construction is rated for wood and metal applications, allowing a single kit to be used on different materials. Its compact form and one-pound weight make it easy to store in a tool pouch or bag.

The kit contains nine hole saws, which is fewer than some larger sets like the 28-piece Milwaukee Ice Hardened kit. Lenox includes a Speed Slot system described as easy to use for plug removal. This practical feature addresses a common task in hole saw operation.

A 60mm cutting depth means you can punch through thick metal stock or layered materials in a single pass, which dramatically cuts down on setup time and fatigue. The carbide teeth are the real story here. They’re built to tear through nail-embedded wood and stainless steel without needing a blade change, making this set a logical pick for plumbers and metal fabricators who face unpredictable materials. It’s for the tradesperson who values a single, durable tool over a cabinet full of specialized cutters.

That versatility and durability come with physical heft. The full kit is a substantial 9.3 pounds, and its 17-inch case won’t tuck into a crowded tool pouch. For jobs exclusively demanding larger diameters in thinner materials, a more focused kit like the Lenox Speed Slot might be a more portable solution. But if your daily drill work mixes metals with tough composites, the Diablo set’s carbide innovation and deep-cut capacity justify its footprint in your on-site kit.

The HYCHIKA HS13B set delivers a lot of utility in one compact case. Its 17-piece count is the main attraction, bundling 11 bi-metal saws from 3/4-inch up to 2-1/2-inch with two mandrels and spare drill bits. This broad range covers the vast majority of common hole sizes for plumbing, electrical, and general fabrication in soft metals and other materials. For a tradesperson or serious DIYer who needs a single, ready-to-go kit for unpredictable jobs, this density of options prevents frequent trips to the supply house. The bi-metal construction and 40mm cutting depth are adequate for sheet metal, conduit, and panels, making it a solid foundational set.

You trade specialization for breadth here. The 40mm depth means you won’t be drilling through thick structural steel or large pipe, and the tooth geometry is designed as a general-purpose workhorse, not for aggressively hard materials. For jobs demanding extreme speed or longevity in stainless steel, a dedicated carbide option would be a better match. But for the user who values having the right size on hand over extreme performance in one material, the HYCHIKA kit organizes a wide capability into a surprisingly small footprint.

An integrated flange prevents drilling beyond the sheet metal, which is a major safety and control feature for working on thin materials like electrical boxes or ductwork. This kit is designed for professionals who need to make clean, precise holes without damaging underlying surfaces. The carbide cutters are described as heavy-duty and durable for long life, and they are specified to cut stainless steel, mild steel, iron, copper, and brass sheet up to 3/16-inch thick. It’s a focused set for repetitive sheet metal tasks.

The trade-off is scope. With just three specific sizes, this isn’t a general-purpose kit for a workshop tackling pipes, wood, or thick plate. You’re buying a specialist tool. For a broader range of hole sizes in thicker materials, a larger bi-metal kit like the Lenox T3 would be a more versatile choice. But for the specific job of cutting clean, depth-controlled holes in sheet metal, the Klein design eliminates a common point of error and waste. It does one job exceptionally well.

A 2-3/8-inch cutting depth allows for 40% deeper holes in a single pass compared to standard hole saws, which significantly reduces the time spent on drilling tasks. The variable tooth design delivers faster cuts with less vibration, enhancing user comfort by reducing physical strain during operation. This single saw is built for users who need that extra reach and value increased productivity.

Since you’re buying just one 3-inch diameter size, it’s a focused tool. If a project calls for multiple hole diameters, the universal mandrel compatibility allows for quick changes between all Diablo hole saw sizes from 5/8-inch to 6-inch. For a user needing only this specific size or replacing a worn-out tool, it delivers focused performance without the cost of a full kit.

Made from M42 bi-metal with 8% cobalt, this hole saw kit cuts about 30% faster than standard saws, a useful advantage for repetitive tasks like installing door hardware or lighting fixtures. Its design includes all-access eject slots for rapid chip clearance and reduced heat buildup, while the saws can last up to twice as long. The set covers ten common sizes up to 2-1/2 inches and comes with arbors, pilot drills, and a heavy-duty case, making it a complete kit for many on-site jobs.

Its range is the main consideration. While the ten sizes cover a lot of ground, the 2-1/2″ maximum diameter means you’ll need another tool for larger holes required for some drain lines or vent stacks. For those bigger, more abrasive cuts, a carbide-tipped option is built to handle it, though it comes at a higher cost per saw. The EZARC kit excels within its intended scope, delivering high-speed performance for the holes you make most often.

With 50 times the life in abrasive applications and the ability to cut over a thousand nails, this carbide hole saw handles materials like cement board, cast iron, and fastener-embedded wood that would quickly ruin other saws. Its 3-tooth-per-inch design cuts faster than many alternatives. The all-access slots also make removing material plugs straightforward, which reduces downtime between holes.

The ten-piece kit offers a focused selection of sizes for its specialized task. When a project requires a wider array of diameters for less extreme materials, other kits like the 13-piece Lenox T3 list more components. This Milwaukee set concentrates on delivering extreme durability in tough applications rather than providing the broadest size range.

A tungsten carbide tipped hole saw built around a unique three-blade design is engineered specifically for hard metals. The separate outer, middle, and inner blades work together to make the cut sharper and more efficient, particularly on tough materials like stainless steel and iron. This makes it a focused choice for metalworkers and fabricators who regularly need clean, 2-1/2 inch holes in sheet metal, square tube, or plate. It’s a specialist tool that prioritizes cutting aggression over material versatility.

With a 1-inch cutting depth, this hole saw is designed for sheet metal and plate up to that thickness, so it’s not meant for drilling through solid structural beams. The instructions specify adding coolant during high-speed work and avoiding materials like concrete or tile. Its three-blade tooth geometry is engineered for efficiency in hard metals, which helps it cut cleanly in stainless steel and iron without bogging down.

With a claim of being twice as durable as previous Lenox models and an optimized tooth design for metal, this hole saw kit is built for a serious workload. The Amazon title specifies it’s a kit for electricians, who often need to punch clean holes quickly and repeatedly. Larger, sharper teeth aim to cut faster, while the Speed Slot staircase design is intended to make ejecting material plugs easier. It includes the most commonly used sizes, which should reduce time spent searching for the right tool.

The trade-off for that ruggedness and speed-focused design is heft. At 7.7 pounds, this is a substantial kit to haul up a ladder compared to a more compact option like the Lenox T3 Bi-Metal kit. It’s a tool built for performance on the job site, not for minimalist portability. For the pro who values time saved on each cut and fewer blade changes over the absolute lightest carry, the trade is an easy one to make.
