9 Best Hole Saw Kit of 2026: Kits That Actually Cut Metal Without Breaking

The SpinLOCK universal arbor accepts hole saws from any brand, enabling tool-free swaps without proprietary lock-ins. The four included cutters cut cleanly through wood, metal, and plastic, with a cobalt-alloy edge that holds up well for moderate use.

This kit works best for DIYers who already own hole saws from other brands and want a single arbor to drive them all. The limited size range (1 to 2.5 inches) covers common electrical and plumbing holes but leaves larger or specialty sizes uncovered. During heavy cuts the arbor may need occasional re-tightening — a known behavior rather than a defect.

The HYCHIKA 17pc bi-metal kit delivers 11 hole saws from 3/4" to 2-1/2" for under $40 — a cost-effective way to cut metal, wood, and PVC on home projects. The wide size range eliminates the need to buy individual saws for common tasks. However, the mandrel shank requires a 1/2" drill chuck, which may be an issue if you have a standard 3/8" drill. Additionally, quality control on the pilot bits and mandrel can vary, with some units experiencing breakage under stress. This set suits DIYers who need a budget-friendly option for occasional use and already have the right drill.

The 28-piece set provides ice-hardened bi-metal hole saws from 3/4" to 4.5", covering the sizes professional contractors need most. The blades cut cleanly through wood, metal, and plastic, and the per-piece cost is lower than buying individually. However, the included storage case is not built for the job site — the plastic posts that hold the saws can crack, prompting many users to replace it with a sturdy organizer.

Tungsten carbide teeth slice through stainless steel, cast iron, and aluminum with noticeably less effort than bi-metal saws. The three sizes (7/8, 1-1/8, 1-3/8 inches) match common electrical panel knockouts and conduit holes, making this a focused metalworking tool rather than a general-purpose kit.

This set suits tradespeople who cut hard metals regularly and want carbide durability without paying Klein or Greenlee prices. The tradeoff: pilot bits are weak and can snap on the first hole, and the limited size range means it won't handle wood, plastic, or larger openings.

The DEWALT Electrician's Set pairs a quick-release mandrel with sizes covering the most common conduit openings, so changing bits on the job is fast. The deeper saw cuts through 2-by material in one pass. The kit skips a 2 in. size, which may be needed for larger conduit. Also, some units have paint on the threads that can interfere with mounting — a quick cleaning solves it.

The Klein 31872 delivers the brand's typical build quality and cuts thin sheet metal cleanly. However, it includes only three cutter sizes (7/8", 1-1/8", 1-3/8") and costs significantly more than competing carbide sets like EZARC that offer similar performance. The carbide teeth can chip on hidden obstructions, so this set is best reserved for electricians who need specific conduit holes in metal panels.

The Milwaukee Hole Dozer 17pc delivers the brand's familiar sharp bi-metal cutting in wood and metal, and the included case keeps the nine sizes organized for toting between jobs. But the savvier buy is the larger 28pc set: weld and tooth alignment varies between units, and the plastic case allows bits to shift out of their slots during transit. For someone who needs a grab-and-go kit and is comfortable inspecting each saw before use, this portable option works—just don't expect the consistency or storage of the bigger set.

KATA's 8-piece set costs well under $10 and delivers functional hole saws for drywall, plywood, and PVC. The carbon steel blades can handle light DIY tasks, though sharpness may vary — some need multiple passes even on soft wood. This kit is for one-off projects on soft materials only; it cannot cut metal and the shallow 1-inch depth limits thicker stock.
