10 Best Hole Saws For Stainless Steel in 2026

The Bosch kit uses an 8% cobalt alloy for increased durability, which helps the hole saws last longer in demanding materials. Its progressor tooth design features alternating teeth size for better performance and longer life in wood, metal, and plastic. Two spinlock universal arbors fit all brands and sizes of hole saws, simplifying diameter changes and enabling fast plug removal without tools.

This is a focused nine-piece kit with six hole saws, two arbors, and a pilot bit, covering common sizes for regular jobs rather than offering an exhaustive range. The plastic case organizes and protects all the components, keeping them together on a job site. Compared to carbide-heavy kits like the Klein Tools set, this bi-metal construction is a general-purpose choice for a variety of materials.

With 23 carbide-tipped hole saws covering diameters from 5/8 inch to just under four inches, this kit is built for the user who needs a solution for nearly any metal-cutting job that comes through the shop. The tungsten carbide construction handles the abrasion of 3mm stainless steel, while the included ejection springs save time and frustration on every cut. It’s the logical choice for a professional or serious DIYer who values having the right size on hand over a compact footprint.

The complete set weighs 14.6 pounds in its carrying case, so it is not a lightweight addition to a tool bag. For comparison, the Klein Tools Heavy-Duty Carbide Hole Cutter Kit is listed at 1.4 pounds. The Dashap kit’s broad size assortment organizes many tools into one box.

This Klein kit is built to cut quick, precise holes in stainless steel, mild steel, iron, copper, and brass sheet up to 3/16-inch thick, which makes it a specialist for thin, hard metals. Its carbide teeth are designed for long life in these materials where other types may dull. An integrated flange prevents drilling beyond the sheet metal, offering control and protecting the workpiece.

The set contains just three sizes: 7/8-inch, 1-1/8-inch, and 1-3/8-inch, so it’s not for jobs requiring a wide range of diameters. For general-purpose hole making in wood, plastic, or thicker materials, a kit like the Bosch HSBIM9 offers more pieces and a broader size range. These Klein cutters are focused on specific sheet metal applications.

Measuring just 4.2 inches in its longest dimension, this Milwaukee kit is designed to take up minimal space. Its carbide teeth are suited for cutting hard materials like stainless steel. The compact form means it can be stored easily in a packed tool bag.

The kit contains ten pieces, which is fewer than many other sets, such as the 27-piece Dashap kit. This narrower size range focuses the selection. The smaller piece count contributes directly to its reduced physical size and weight.

The ability to cut clean holes up to 12 inches in diameter makes this tool unique for large openings in sheet metal. For HVAC pros or metal fabricators installing duct collars, register boxes, or equipment knockouts, this adjustable cutter replaces an entire set of large-diameter hole saws with one compact tool. Its lightweight aluminum frame is a genuine advantage when you’re moving between job sites all day, as it stores in a pouch like a standard hand tool. The precision sealed bearings and English/metric gauge ensure smooth, vibration-free cuts at your exact required size.

Designed for sheet metal, the Malco HC1 handles 20-gauge galvanized steel, aluminum, copper, and 22-gauge stainless steel, so it covers common HVAC and ductwork materials. Its trade-off is material capacity; for thicker stainless plate, a carbide hole saw like the Klein Tools kit would be required. Value comes from the adjustable 2-inch to 12-inch diameter range, making this a specialist tool that pays for itself on jobs where fixed-size cutters can’t reach.

Because its deeper saw design cuts 2-by material in one pass, this DeWalt kit can save significant time on repetitive jobs. The patented toothforms optimize chip removal for efficient drilling, which the brand states contributes to up to 50% longer life compared to prior generations when cutting black pipe. Made in the U.S.A. with global materials, this set is built for the professional needing versatile performance across wood, metal, and plastic.

The trade-off is the cutting technology itself. While the high-speed steel edge is versatile, it’s a bi-metal design, not carbide-tipped like the Milwaukee Big Hawg or Klein Tools kits. For all-day drilling into hardened stainless, a carbide tooth will typically outlast it. This DeWalt set is about dependable, multi-material performance rather than being a specialist for the absolute toughest metals. For an electrician dealing with wood panels, plastic enclosures, and thin-gauge metal daily, it’s a thoroughly capable workhorse.

An 8% cobalt bi-metal construction allows this saw to cut materials up to 30% faster and last up to twice as long as standard versions, which saves time on repetitive tasks. The kit handles common jobs like installing door hardware, lighting fixtures, or pipes in materials ranging from thin metal and plywood to PVC. Its organized case with ten sizes from 3/4-inch to 2-1/2 inches makes it a practical, ready-to-use set for various installations.

The maximum cutting diameter is two and a half inches with a depth of 1.89 inches, so it cannot handle openings for large plumbing vents or very thick, stacked materials. Among the other listed products, kits like the Dashap 27-Piece or METOTY 19-Piece offer larger maximum diameters, while the Milwaukee Big Hawg is another carbide option. For the hole sizes it includes, however, the EZARC set provides efficient cutting for a wide range of sheet goods and thin metals.

With 13 carbide-tipped hole saws covering diameters from 1/2 inch to 2-1/8 inches, the KJE kit provides a complete range for common hole sizes. Its triple-blade design and titanium-plated carbide teeth with an HRA 89.5 hardness resist wear during tough cuts. The manufacturer recommends using coolant for continuous high-speed drilling to manage friction heat.

The set’s maximum diameter of 2-1/8 inches is smaller than some other kits, like the Dashap set which goes up to 3-15/16 inches. The included titanium pilot drills are reinforced to resist breakage, which helps maintain precision. Following the safety guidance to wear protective goggles and gloves is advised during operation.

Covering sizes from 1/2 inch to 2-1/8 inches, this 13-piece carbide-tipped set handles the common hole diameters needed for metal projects. Its industrial-grade carbide teeth resist wear and rust, which helps them cut through hard materials like stainless steel without dulling quickly. The kit also includes three titanium-plated pilot drills and three L-wrenches, providing multiple pieces of the most frequently used components.

The trade-off is in specialization and heft. The 5.4-pound kit has substance, but it’s focused solely on metal. You can’t grab one of these for a quick pass through wood or tile. For larger diameter work, you’ll hit the 2-1/8″ ceiling and need to look at a kit like the Dashap 27-Piece. For a pro who only needs a few specific, frequently used sizes and demands maximum durability, a dedicated heavy-duty option like the Klein Tools carbide cutter might be a more efficient long-term purchase. This METOTY set excels at providing a complete, ready-to-go toolbox solution.

The 48mm cutting depth is the key spec, allowing you to bore cleanly through thicker boards and deeper openings where a standard 38mm saw would bottom out. This makes the KATA kit a logical choice for plumbing, electrical, and remodeling jobs where you’re routing pipe or conduit through dimensional lumber. The M42 8% cobalt bi-metal construction offers better heat resistance for the long cuts this depth allows, and the included hard case keeps all sixteen sizes and the arbor ready for the jobsite.

With its M42 8% cobalt bi-metal construction, this hole saw is built for durability and heat resistance, which translates to a longer cutting life across many common jobsite materials. It’s designed to cut clean holes in wood, plywood, drywall, PVC, plastic, aluminum, and thin metal sheet. The manufacturer specifies it is not for use on tile, concrete, brick, stone, glass, masonry, or thick hardened steel.
