How to Choose a Bi-Metal Hole Saw Set? Best Picks for 2026

Stop buying single hole saws—a well-chosen bi-metal hole saw kit will save you money and headaches for years

Why You Need a Bi-Metal Hole Saw Set, Not Just Singles

Most people start by buying hole saws one size at a time—just whatever they need for the job at hand. A few projects later, they've got a messy pile of mismatched cutters, half of them dull or missing, and they've ended up spending more than if they'd just bought a complete hole saw set from the start.

A good bi-metal hole saw kit gives you:

• Better value—bundled sets cost far less than buying each size individually

• Easy organization—most kits come with a dedicated storage case so you always know where each size is

• Consistent quality—every cutter in the set shares the same reliable build standard

• Fewer trips to the store—you have the right size on hand when you need it

By 2026, the market is packed with options, from budget-friendly homeowner kits to heavy-duty professional hole saw sets. Below, I've compared the most popular and best-value models available right now.

Key Factors to Consider When Buying a Bi-Metal Hole Saw Kit

Before we dive into specific products, here's what actually matters when comparing hole saw sets:

1. Size Coverage

• For general home use/renovation: 16mm to 76mm (5/8" to 3") covers most common needs

• For pipe/electrical work: look for kits that include 64mm, 76mm, or larger sizes

• Pro tip: Kits with odd-number sizes (19mm, 29mm, etc.) actually cover more applications than standard even-number sets

2. Cutting Depth

• Standard depth: ~38mm (1-1/2")—fine for drywall, thin wood, and sheet metal

• Deep-cut models: 51mm (2") or more—essential for thick lumber, conduit, and pipe

• 2026 trend: more brands are offering extended-depth bi-metal hole saws as standard

3. Arbor System (Quick-Change vs. Thread-On)

This is a huge time-saver:

• Thread-on arbors (old style): need a wrench or key to change cutters—slow and annoying

• Quick-change arbors (Snap-Lock, Fast-Lock, etc.): swap cutters in seconds, no tools required

• 2026 recommendation: only buy kits with tool-free arbor systems if you use them regularly

4. Pilot Drill Bit Quality

The pilot bit does the heavy work of centering and starting the cut:

• Look for replaceable pilot bits—some kits include spares

• High-speed steel (HSS) or carbide-tipped pilots last longer

• 2026 models increasingly feature split-point pilot drills for cleaner starts

5. Carrying Case / Storage

A good case with molded slots for each size protects teeth from damage and makes selection quick. Avoid kits that just throw cutters into a zipper bag—you'll waste time searching and end up with dull edges.

Best Bi-Metal Hole Saw Kits for 2026 — Detailed Reviews

1. Diablo DHS14SGP — Best for Quick-Change Efficiency

Diablo (a top-tier brand from Freud) consistently leads the bi-metal hole saw set market, and the DHS14SGP is their standout 2026 offering. Its Snap-Lock Plus arbor system lets you swap cutters without any tools—just snap on and go. With a 60mm (2-3/8") cutting depth, it powers through thick stock in one pass.

Verdict: The best hole saw kit for speed—if you're on the clock, this saves hours.

2. Makita D-63993 16-Piece Set — Best Storage & Precision

Makita's D-63993 is a 16-piece bi-metal hole saw kit that excels in two areas: storage and precision. Each cutter has its own threaded locking mount inside the case—no rattling, no lost pieces, and you can grab the size you need instantly. Made from cobalt-enriched bi-metal, these cutters chew through metal studs, conduit, and pipes with ease.

Verdict: The best-organized hole saw set on the market—worth the extra cost if you move between job sites.

3. IRWIN 1200G 17-Piece Set — Best Full-Range Coverage

IRWIN has been making hole saws for decades, and their 1200G 17-piece kit is the most comprehensive bi-metal hole saw assortment you can buy in 2026. It includes 12 sizes from 16mm all the way to 76mm (5/8" to 3"), covering nearly every common drilling scenario. Teeth are electron-beam welded for superior retention—they stay sharp longer and resist stripping.

Verdict: The most complete hole saw kit for all-around use—buy it once and you're set.

4. Starrett 7-Piece Deep-Cut Set — Best for Thick Metal & Conduit

Starrett is the gold standard for precision tools, and their KDC05021 7-piece deep-cut set is purpose-built for electricians and pipefitters. With a 51mm (2") cutting depth, it handles thick-wall conduit, pipe, and heavy gauge steel in a single pass without flipping the workpiece. The M42 cobalt bi-metal construction offers superior heat and wear resistance.

Verdict: The best deep-cut hole saw kit for heavy metal work—worth every penny for pros.

5. Life Palette 16-Piece Set — Best Budget Option

If you're on a tight budget or only need a hole saw once in a while, Japan's Life Palette 16-piece set is the cheapest way to get a wide size range (16mm to 100mm). However, you get what you pay for—online reviews consistently note arbor wobble, poor centering, and breakage under load. Only consider this if precision and durability aren't critical.

Verdict: Cheap hole saw set that gets the job done—but don't expect it to last.

How to Choose the Right Bi-Metal Hole Saw Kit for Your Needs

Ask yourself these two questions:

1. What material are you cutting most often?

• Wood, drywall, plastic: any bi-metal set with standard depth will work fine

• Metal studs, conduit, steel pipe: choose cobalt-enriched or M42 bi-metal—they resist heat and tooth wear much better

• Thick lumber or pipe: you need a deep-cut set (51mm or 60mm depth)

2. How often do you use it?

• Daily use (professional): invest in tool-free arbor systems (Diablo) and premium storage (Makita)—the time savings pay for themselves

• Weekly/monthly (serious DIY): IRWIN 1200G gives you the best all-in-one value

• Once in a while (casual): Life Palette is cheap, but consider buying quality singles instead if reliability matters

Quick Summary: Which One Should You Buy?

Final Thoughts

A bi-metal hole saw set is one of those purchases where buying quality upfront saves you time, money, and frustration down the road. In 2026, you have great options across every price tier—but the sweet spot for most users is IRWIN 1200G for full coverage, Diablo DHS14SGP if speed is king, and Makita D-63993 if you value organization.

Skip the cheap singles. Buy a proper hole saw kit, keep it in its case, and you'll reach for it project after project with confidence.
